# How Many Cubic Feet In A 20 Lb Propane Tank?

A gallon of Liquid Propane Gas (LPG) equals 36.39 cubic feet of Propane Gas, while a 20lb bottle contains 4.6 gallons of Propane. In a 20lb bottle, there’s 167.4 cubic feet of vaporized propane.

## In a gallon of propane, how many cubic feet of gas are there?

“PROPANE” refers to a gaseous paraffin hydrocarbon that turns liquid under pressure or at low temperatures, which is found naturally in crude petroleum and natural gas and can also be created by cracking, in either gaseous or liquid form.

INFORMATION ON COMPRESSED PROPANE (GASEOUS FORM) EQUIVALENCE: At 60 degrees Fahrenheit and 14.73 pounds per square inch (psi),

“NATURAL GAS” refers to naturally occurring mixes of hydrocarbon gases and vapors, primarily methane, in both gaseous and liquid form.

INFORMATION ON NATURAL GAS (GASEOUS FORM) EQUIVALENCE: At 60 degrees Fahrenheit and 14.73 pounds per square inch (psi),

The amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit is measured in “British Thermal Units” (Btu).

The amount of gas occupying a cubic foot of space at a pressure of 30 inches of mercury (about 14.7 psi) and a temperature of 60 degrees Fahrenheit is defined as a “cubic foot,” which is a standard unit of gas measurement.

A gallon is a unit of volume that equals 231 cubic inches. It refers to a gallon of liquid natural gas or other liquid fuels at a temperature of 60 degrees Fahrenheit when employed as a standard unit of measure.

To convert liters to gallons, multiply the number of liters by 0.26417 to get the equal quantity in gallons.

When temperature and pressure corrections are required (e.g., when motor vehicle fuels are not tested at 14.73 psi or 60 degrees Fahrenheit), consult the National Institute of Standards and Technology Handbook No. 44 (1991).

## When a 20-pound propane tank is full, how much does it weigh?

The most popular size of BBQ propane tank is 20 lb. It can also be used to fuel a number of propane heaters and even propane generators.

The dimensions of a 20-pound propane tank are 8 inches length and 4-inches wide. According to the 80 percent safety guideline, a 20 lb propane tank can hold a total of 16 lb of propane.

The empty 20-pound propane tank weighs around 13.5 pounds. Aluminum 20 pound propane cylinders are lighter than steel cylinders.

On average, a full 20-pound propane tank weighs 29.5 pounds. To determine the total, add the 16 pound of propane to the empty weight (13.5 pound) of the 20 pound propane tank.

Overall, a 20 pound propane tank has a lot of BTUs. What is the precise number of BTUs in it?

344,470 BTUs are contained in a 20 pound propane tank. That’s enough to keep a 10,000 BTU/h heater running for several days (34.4 hours, to be exact).

## How do you calculate a propane’s volume?

(mod)re: how to convert cubic feet gas meter readings to gallons of propane on 2017-04-17

The American AC-95 LP gas meter does not have a thorough specification, but a check at its data tag right on the propane meter reveals that it is a temperature-compensated meter that reads gas usage in cubic feet at 60 degrees Fahrenheit.

Temperature and pressure must be taken into account when reading gas volumes, as explained in the article GAS BTUH, CUBIC FEET & ENERGY.

At 60 degrees F, one gallon of LP-gas (propane or C3H8) weighs around 4.20 pounds, contains roughly 8.66 cubic feet of gas vapor per pound, and…

At 60F, one gallon of LP gas equals (4.20 pounds x 8.66 cuft/lb) = 36 cu.ft. of gas vapor per gallon.

How do I figure out how much propane my American Meter Division AC-95 propane meter has used?

The initial reading was 8575, and the final reading was 8623, which equaled 48. Do I multiply 48 by 7.48052 to obtain the number of gallons used?

But, in any case, I believe that giving a generic answer is risky; naming an orifice without knowing the pressure and fuel being converted (TO or FROM) is unsafe. The best strategy is to ask the issue directly so an engineer won’t duck it, then look at your smoker to determine the brand and model, and then ask the manufacturer to send you the appropriate orifice parts.

Can you provide me with the correct orifices in a conversion kit so that I can convert my BrandX ModelY smoker (which you produced) from LP gas to natural gas?

I have a #48 orifice in a five burner smoker (a 302470) and am looking for the proper size orifices to convert it to a three burner smoker.

Can a 200.000 btu gas control valve be used on a 75.000 btu furnace? On 2017-03-03 by (mod)re:Can a 200.000 btu gas control valve be used on a 75.000 btu furnace?

Hi, Thank you for your response. My valve specifies a maximum pressure of 200.000 psi. I believe this valve will function on any pressure up to 200.000 psi. Thank you for answering my question. Terry

Terry, I’m not sure. Examine the gas control valve’s labeling or look for its specification page. The 200kBTUH value may indicate the valve’s maximum capacity; the spec sheet will list the valve’s operating range in btus.

On 2016-11-08by (mod)re:If we use 150 cubic meters (liters) of gas vapor every day at a price of 50 cents per liter, What is the price per cubic meter M3 of vapor?

Thank you for asking such a great question. Temperature is a source of difference in estimates of converting a volume in liters of LPG (liquid) to a volume in cubic meters of propane, as you’ll see in a moment (gas)

LPG liquid volume in litres to propane gas volume in m3: 1L LPG= 0.27m3 gas

This is the essential recipe.

If 1 liter costs \$0.50 (50 cents per liter), 0.26 cubic meters of gas costs \$0.50.

1 cubic meter of propane gas (1m3 = 3.70L) equals 3.07 litres of LPG liquid.

How to convert liters of liquid propane (LPG) into cubic meters of propane gas:

How to convert cubic meters of propane gas to liters of liquid propane gas:

At 8 degrees Celsius, 1 cubic meter of LPG (gas) equals 3.93 liters of propane gas vapor.

Other sources list the conversion number as 3.67, or officially 3.85 in the European Union.

Why are there so many different conversion numbers? Because the volume of gas vapor produced by a liter of liquid LPG is affected by the ambient temperature.

To get around the temperature issue, some sources prefer to operate with units of energy (gigajoules), but we’ll leave that aside for now to avoid drowning you in numbers.

Hello, I’m hoping you can assist me. My main LPG tank is equipped with an old-fashioned gauge and my fuel is delivered in liters.

So we installed a second gas meter that reads in cubic meters of vapor, but we can’t figure out how to convert it.

What is the cost per cubic meter of vapor if we utilize 150 cubic meters of vapor per day at 50 cents per liter?

If the building has 2 pounds natural gas pressure coming in from the street, how much BTU are accessible in total?

In Kentucky, I reside in a pretty rural location (moderate winters). And I want to put in a 25k BTU vent-free fireplace to support my electric heat pump when it gets really cold or when there are power outages. Do you have any suggestions for how much LP Gas I should buy to get through the winter?

Any recommendations for average daily operating hours for LPG-fired boilers at a 5-star hotel?

I know how much LPG the boiler uses per hour and want to size the LPG storage tank accordingly.

Example: Tank Capacity = Average Daily Operating Hours x LPG Consumption for One Hour X Storage Days (say 10 Days).

On 2016-06-23, (mod) re: the impact of switching from natural gas to propane on appliance BTUh

The conversion will modify the pressure, regulator, and jets, but you should be able to get the same BTUh output (different orifices)

In one hour, a 200,000 BTU/hr furnace will utilize around 194 cubic feet of natural gas (100,000 1,030 = 97.1 x 2)

In one hour, a 200,000 BTU/hr heater will utilize around 80 cubic feet of propane (100,000 2516 = 39.7 x 2)

What would the btu output be on propane if I have a 200,000 btu heater that is now running on natural gas and want to switch it to propane?

If I understand the question well, some of your clients are using “non-standard” natural gas; the gas-burning appliance MUST be appropriately matched to the fuel qualities; otherwise, the risk is not only poor performance, but also corrosion and lethal CO threats.

Because metering devices, orifices, and controls may not function properly or safely, you cannot just change the gas pressure. I’d contact the manufacturer of the heater you’re planning to install and inquire about any product part modifications or adjustments that are required.

I am a hvac technician from West Virginia. People consume a lot of well head gas (natural gas). Contains 2100 btu and has a gravity of 1.6. How do I deal with this when installing a new furnace?

On 2016-01-20 by (mod)re: How much propane does a 50 gallon propane hot water heater use?

To address your query, you can apply the formulas in the article GAS BTUH, CUBIC FEET &ENERGY: to make an exact calculation, look at the INPUT BTUH value on your water heater’s data tag.

For a 30 to 40 gallon water heater, a typical residential water heater uses roughly 45,000 BTUH to produce domestic hot water.

A gallon of liquid propane has around 91,500 BTUs and weighs approximately 4.20 pounds. A pound of propane has around 21,500 BTUs in it.

(mod)re: how to convert cubic meters of gas per hour to liquid gallons of propane used on 2015-11-10

David Because a square meter is a bit flat, I’m guessing your meter, if it’s metric, is reporting cubic meters per hour.

The reading on my propane meter is square meters per hour.

How can I figure out how many gallons I used?

## What is the capacity of a 30 pound propane tank in gallons?

A 30 pound propane tank holds 7 gallons and weights 55 pounds when filled. Large commercial barbecues, construction heaters, space heaters, propane hawk torches, and a variety of other propane applications all use the 40 pound propane tank.

## A pound of propane equals how many gallons?

The Straightforward Answer Simply put, 1 pound of propane equals 0.236 gallons. When the propane tank temperature is 60 degrees Fahrenheit, this is true. 23.6 gallons = 0.236 gallons times 100 pounds A 100 pound.

## What is the weight of a gallon of liquid propane?

The weight of a gallon of propane is 4.11 pounds. That is, if you measure it at 77 degrees Fahrenheit.

It’s vital to remember that LPG’s density of 4.11 lb/gallon only applies at room temperature (77F).

Gases (even liquified gasses like liquid propane) expand at higher temperatures and contract at lower temperatures, as we all know. As a result, when we calculate how much propane weighs per gallon, we must additionally factor in the temperature.

This also explains why the 80 percent maximum filling guideline is necessary when filling propane tanks. In the third section, we’ll utilize this rule to figure out how many gallons a 20-pound propane tank can contain. A 20-pound gas tank can only carry 16 pounds of propane.

To demonstrate that a gallon of propane does not always weigh 4.11 pounds, here are some propane densities at various temperatures:

Higher temperatures cause the density of propane to decrease, the volume of propane to increase, and the pressure within a propane tank to rise.

Reduce the temperature by increasing the density of propane, reducing the volume of propane, and lowering the pressure inside a propane tank.
