There are about 1030 BTUs in a cubic foot of natural gas. If one wishes to know the gas consumption (in feet3 per hour) for a given BTU per hour usage rate, one would divide the amount of BTUs by 1030. That would yield the number of cubic feet of gas that is used per hour. Q: I'm heating a space using 10,300 BTUs per hour and I'm using my natural gas heater to do it. How many cubic feet of gas am I using per hour? A: 10,300 BTUs (the heat generated per hour) divided by 1030 (the number of BTUs per cubic foot of gas) equals 10 cubic feet. You're using 10 cubic feet per hour. You apply 10,300 BTUs to heat the space per hour, and you use 10 cubic feet of gas per hour to do that. (And yes, I picked easy numbers.)
There are many btu's but the most common ones are:oxygencarbon deoxide (co2)carbon moxide(co3)water vapor (h2o)
If you are looking for an easy method that is not based in scientific data try this: Heating requirement is the same as cooling. To calculate Btu needed to cool look at the furnace for input Btu then multipy that by effeciency of unit. Now think about the coldest day the furnace will provide okay heating such as 5 degrees outside and 68 degrees inside. Subtract those and you have 63 degrees. If you heating Btu was 80000 input and 80% efficient, you need 64000 btu to heat 63 degrees. Do similar math to hottest day and desired inside cool temperature. Maybe 103 degrees outside and 72 degrees inside. That is 31 degrees difference. Use heat math of 64000 Btu for 63 degree which is very roughly 1000 Btu per degree. Apply that to cooling and it's roughly 31000 Btu, or around 2-1/2 ton cooling. Please don't bark at me about the basic nature of my math-I thought I would explain this as a method to start or get an idea. There is a method that accounts for all factors but no way could I explain it. Also, if using electric heat your btu will be about 4.5 per watt and no efficiency applies. The watts can be found on the inside of the furnace above the blower.
The BTU output of a double barrel wood stove typically ranges from 20,000 to 40,000 BTUs per hour, depending on its size, design, and the type of wood used. These stoves are efficient for heating small to medium-sized spaces and can vary in performance based on airflow and fuel quality. It's important to check the manufacturer's specifications for the exact BTU rating of a specific model.
HVAC Load Calculation is a formula used by a contractor salesmen that determines the proper tonnage size of heating and cooling systems to be installed in Residential or Commercial applications. The formula is used to calculate the total cooling and heating BTU'S (British Thermal Units) for the proper values of determining the correct tonnage to be installed in HVAC applications. Tonnage is the size of the HVAC system. Without this Load calculation the wrong tonnage could be installed and it causing to much humidity in the summer in cooling season and not enough heating in the winter season. Also the HVAC system may never stop running to reach the proper temperature that the thermostat is set for. Thus causing high electricity out of pocket cost.
Step 1 - Find the volume of the room in cubic metres: * Calculate length x width x height Step 2 - Adjust according to room type: * Lounges and dining rooms multiply by 50* Bedrooms multiply by 40* Common areas and kitchens multiply by 30* Bathrooms multiply by 90Step 3 - Allow for important variables: * For rooms facing north add 15%* For French windows add 20%* For double glazing deduct 10%* For very exposed sites, or very cold weather add 10%* For new builds (that are much better insulated) deduct 20% This will give you the output of any radiator in watts.Multiply this by 3.412 to give the BTU requirement for the room.
btu of natural gas to btu of propane
The heat content of natural gas is typically measured in British Thermal Units (BTU) per standard cubic foot. The range can vary but it's commonly around 1,000 BTU per cubic foot. When calculating BTU per square foot, you would need to factor in the gas consumption rate to determine the BTU output for a specific area.
102,000 BTU = 1 ccf
Ther are 1,050 BTU in one cubic foot of natural gas.
138,700 btu's
Natural gas has the highest BTU content when burned.

The average is about 20,000 BTU's per pound at standard temperature and pressure.
According to the United States Energy Information Administration (EIA) in 2010, total energy consumption was 523.9 quadrillion British Thermal Units (Btu). Of this, 56.2 quadrillion Btu, or 10.7% was from renewable sources, and 27.3 quadrillion Btu or 5.2% was from Nuclear sources. The balance of 84.1% came from fossil fuels.
According to the United States Energy Information Administration (EIA) in 2011, total energy consumption in the United States was 97.7 quadrillion British Thermal Units (Btu). Of this, 6.8 quadrillion Btu or 7.0% was from renewable sources, 0.67 quadrillion Btu or 0.69% was from Biofuels, and 8.3 quadrillion Btu or 8.5% was from Nuclear sources. The balance of 83.81% came from fossil fuels.
