One therm is equal to 100 cubic feet of natural gas. Most households use natural gas for heating the home, heating water, and appliances.
How much is a therm in natural gas?
A therm is a measurement of the amount of heat energy in natural gas, equal to 100,000 BTUs. A BTU, or British Thermal Unit, is the quantity of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
What is a therm gas bill?
Natural gas is billed to customers in therms. A therm is 100,000 BTU and is a measure of heat content. For reference, one gallon of gasoline contains approximately 125,000 BTU or 1.25 therms. The utility meter doesn’t read therms, instead it measures the volume of natural gas that passes through the meter each month.
How do you calculate natural gas therms?
Multiply the BTU input of your natural gas appliance by your monthly usage in hours, using a calculator. For example, 74,000 x 5 = 370,000. Divide your answer by 100,000. For example, 370,000/100,000 = 3.7.How many therms of gas does it take to heat a house?

How much propane will a 30 000 BTU heater use?
A gallon of propane weighs approximately 4.2 lbs. A gallon of propane has a burn rate of approximately 100,000 BTUs (British Thermal Units) per hour. This means that if you run your heater continuously (30,000 BTUs) you will be consuming propane at a rate of about 1/3 gallon per hour.
How long will a 30000 BTU heater run on a 20 lb tank?
A pound of propane has 21,591 btu. So if you had a 21,500 btu heater it would run basically 20 hours on a true 20lb bottle. With a 30,000 btu heater you multiply 21,500×20(pounds)=430,000 and divide by your heater size of 30,000btu. Which gives you 14.34 hours if you run it at full all the time.
