You may be asking how to convert gas measures now that you’ve learned about some typical gas measurements. Fortunately, all that is required for a gas unit conversion is some basic multiplication.
A natural gas conversion table for commonly used natural gas measures may be found below.
Natural Gas Conversion Table
Let’s make a quick math to see what we’re talking about. Let’s imagine you’re trying to figure out how many BTUs are in a m3 of gas. We may start by looking up how much MMBtu (million British Thermal Units) are in a cubic metre of gas using the table above. You would multiply 1 m3 by 0.0353, giving you 0.0353 MMBtu for 1 m3 of natural gas. To convert this figure to BTUs, multiply it by 1000000, which is 35300 BTUs per m3 of gas.
What is the formula for calculating BTU for a gas meter?
General safety warning: inappropriate natural or “LP” gas installation, as well as poor inspection and testing methods, can result in harmful conditions, including fire or explosion.
If you smell gas, leave the building immediately and avoid doing anything that could cause a spark, such as turning on a light switch or dialing a phone number. Call your gas company’s emergency number and/or your local fire department from a safe area. The text supplied here is a rough draft that may be erroneous or incomplete.
Gas meters by American Meter Company are shown at the top and left of the page. The AC250 is at the top of the page, and we have further information about it at the end of this article. The American Meter – Singer Co. is just above it. Gas meter AC-95.
How to Calculate, Measure, and Set LP “Bottled” Gas or Natural Gas Pressures & BTUH per Cubic Foot is discussed here. What are the normal pressures in an LP or natural gas fuel system, and how do they differ? What is the distinction between butane, propane, and natural gas? Can we just use butane instead of propane or LPG?
How to calculate the BTU capacity of LP or natural gas fired equipment, heaters, or appliances
Computing BTUH: Technical Note: You can calculate your gas-fired equipment’s BTUs per hour of gas usage. Make sure only one gas appliance is on and keep an eye on the gas meter to see how long it takes to utilize one cubic foot of gas.
The amount you calculate for an appliance’s BTU capacity should be close to the nameplate “input” BTUH on the device.
How many cubic feet of natural gas or propane will a heating furnace or boiler consume per hour?
- In an hour of “burner on” time, a 100,000 BTUh furnace will use around 95 cubic feet of natural gas (100,000 1,050 = 95.21).
- In an hour of “burner on” time, a 100,000 BTUh heater will use around 40 cubic feet of propane (100,000 2500 = 40).
How to calculate the conversion ofgallons of propane or natural gas to pounds or BTUs or to volume of gas
A gallon of propane has around 91,500 BTUs and weighs approximately 4.20 pounds. A pound of propane has around 21,500 BTUs in it. The details of the calculation are listed below.
At 60 degrees Fahrenheit, one gallon of LP-gas (propane or C3H8) weighs about 4.20 pounds, contains about 8.66 cubic feet of gas vapor per pound, burns at 3,595 degrees Fahrenheit in air, and takes 23.86 cubic feet of combustion air to burn correctly.
When converting between cubic feet of gas and liquid gallons, keeping the temperature constant aids in decoding common cubic foot gas meter values.
- At 60 degrees Fahrenheit, 1 gallon of LP gas C3H8 weighs 4.20 pounds and holds 8.66 cubic feet per pound.
- Per gallon of LPG, 4.20 pounds x 8.66 cubic feet/pound Equals 36 cubic feet of gas (at 60F).
- At 60F, 1 cubic foot of LP gasC3H8 equals 1/36 gallon of liquid LP or around 0.3 gallon of liquid LP.
Butane Gas Properties
Butane gas (C4H10) has a different set of numbers. One gallon of butane-based LP gas costs:
- Per pound, 1 gallon of butane contains approximately 6.51 cubic feet of gas vapor (at 60 deg. F),
- to smolder To burn correctly, 1 gallon of butane takes 31.02 cubic feet of combustion air.

What are the common operating pressures of natural gas and LP or “liquid petroleum” gas in the building gas piping and at the appliance?
There are details on LP gas pressures and natural gas pressures in buildings and in gas-fired appliances.
What is the energy content of one cubic meter of natural gas?
Natural gas is used in Natural Gas Vehicles (NGVs) in the same way that it is piped into millions of households for cooking and heating.
Natural gas is a fairly simple fuel at the molecular level. Methane (CH4), which is only one carbon atom with four hydrogen atoms connected, makes up around 90% of natural gas, with propane, butane, and other components making up the rest. The composition of natural gas varies depending on the source.
Hydrogen, which is actually an energy ‘carrier’ rather than an energy source, is the only simpler fuel accessible. Because there is currently no cost-effective technique of producing and delivering significant amounts of hydrogen, natural gas will continue to be the clean fuel of choice for some time. Natural gas is frequently utilized as a feedstock due to its high hydrogen content, which is one of the reasons why natural gas cars are sometimes referred to as the “road to the hydrogen economy.” Ultimately, a natural gas infrastructure investment is a hydrogen infrastructure investment.
Because natural gas takes up more space than typical liquid fuels, it must be compressed or liquefied before being used in transportation. NGVs are most commonly used with compressed natural gas (CNG), while Liquefied Natural Gas (LNG) is becoming more popular. The refueling page has more information about the various steps.
It is critical to evaluate the energy content of fuels when evaluating pricing. CNG is sold by the kilogram or cubic meter (m3), while LNG is sold by the litre. Natural gas has about 38.3* megajoules per cubic metre (MJ/m3), which is about the same amount of energy as a litre of diesel (38.8* Mj/l). CNG or LNG is marketed by the Gasoline per Gallon Equivalent (GGE) or Diesel per Gallon Equivalent (DGE) in various countries (DGE). Because the energy content has already been taken into consideration in these circumstances, a direct comparison of gasoline prices may be done.
In natural gas, how do you compute BTU?
Divide your therm by 100,000 BTUs to get the BTUs per pound (100 cubic feet or 1 standard therm). Multiply the value by 5.66 to get the number of BTUs per GGE (1 standard GGE). For example, if your area’s therm is 4.96 lbs, divide that figure by 100,000 to get the corresponding BTUs per pound.
What is the BTU value of a cubic foot of heating?
The underlying equation of a heating and cooling system is how much you want to add or remove from the air within a building. That depends on a variety of factors, including square footage and environment, but the beginning point is determining how many degrees you want to raise the interior temperature and how many BTUs are required to do so. There are calculators available to assist homeowners in determining the proper unit size, but there are also some general guidelines to follow. A 300 square foot space, for example, normally requires 7,000 BTUs to maintain a pleasant temperature, whereas a 1,000 square foot room necessitates 18,000 BTUs.
BTUs needed per hour = (desired temperature change) x (cubic feet of space) x.133
What is the price of a cubic foot of natural gas?
Natural gas per therm average price That works out to $0.95 per CCF. It’s a natural gas therm price of $0.92 based on the national average heat content of 1,037 Btu per cubic foot in 2019.
What is natural gas’s heat content?
The quantity of energy released when a volume of natural gas is burned varies depending on the extent to which gases with higher heat content than methane are contained in supplied gas. In the Natural Gas Monthly, the EIA now publishes the heat content of end-use natural gas by state.
At standard temperature and pressure, methane, the principal component of natural gas, has a heat content of 1,010 British thermal units per cubic foot (Btu/cf).
The heat content of natural gas in the United States in July 2014 was roughly 1,030 Btu/cf, over 2% more than pure methane, owing to the makeup of the gases in the natural gas stream.
To burn correctly, natural gas has a specific fuel-to-oxygen ratio, hence stoves and other gas-fueled appliances normally require natural gas to be within a set Btu range.
Pipelines have a range of allowable Btu content for natural gas passing through their systems, which varies from pipeline to pipeline.
Natural gas liquids (mainly ethane and some propane) with higher heat content than methane are found in higher concentrations in high-Btu natural gas.
The heat content of pure ethane is 1,770 Btu/cf, while pure propane is 2,516 Btu/cf.
During natural gas processing, liquids are frequently eliminated.
Due to the low price of ethane, many natural gas processors are opting to leave it in the natural gas stream rather than remove it for sale as a separate commodity, a technique known as ethane rejection.
Ethane rejection could be indicated by a significantly high Btu content in a particular condition.
Ethane is also more likely to be rejected in areas with processing restrictions or low ethane demand. The Marcellus Shale play in Pennsylvania, West Virginia, and Ohio, as well as the Bakken formation in North Dakota, demonstrated this in 2013. In July 2014, the average heat content of natural gas delivered in West Virginia and North Dakota was 6% and 5% higher, respectively, than the national average.
Other factors, such as the presence of carbon dioxide or other nonhydrocarbons that remain in the natural gas stream after processing, state and local regulations, and the presence of straddle plants (or downstream gas processing plants) that remove components from the dry gas stream, can all contribute to variations in the average heat content of natural gas across states.
What is the maximum BTU capacity of my gas meter?
A gas meter with a maximum continuous capacity of 250 cf/h can deliver a maximum of 250,000 Btu/h. The size of your gas meter is allowed if the continuous meter capacity exceeds demand. So, in the example above, a residence with a total demand of 200,000 Btu/h will be acceptable with this gas meter.
What does m3 mean on a gas meter?
This meter counts gas consumption in cubic metres (m3) and typically shows five digits, a decimal point, and then additional numbers. Near the readout on digital gas meters, the units ‘M3? will be displayed.
To read the meter, write down the first five numbers, including any zeros, from left to right. Any numbers after the decimal point or space, which may also be highlighted in red, should be ignored.
To convert imperial gas meter readings to kWh:
- To calculate the volume of gas utilized, subtract the new meter reading from the prior reading.
- Multiply by 0.0283 OR divide by 35.315 to convert from cubic feet to cubic meters.
What is the formula for converting m3 of gas to kWh?
- Calculate how many units were consumed within a billing period. At the beginning and end of this session, take a meter reading.
- Subtract the first and second meter readings to get the total amount of gas consumed during this time period.
- Multiply this amount by the calorie value to get the calorific value. Calorific values may differ slightly, however they will be clearly mentioned on your bill. In our calculations, we assumed an average of 40 megajoules per cubic metre as the calorific value.
- Multiply this number by 1.02264 to get the answer. This is the correction factor, which takes into account temperature and pressure changes as the gas expands and contracts.
Isn’t it simple enough? Let’s take a 100m3 meter reading and convert it to kWh as an example:
