13,000 Therms equates to 1,300,000,000 BTU
1 Therm is equal to 100,000 BTU.
The therm is a non-SI unit of heat energy equal to 100,000 BTU.
There are 100,000 BTU (British Thermal Units) in a therm.
The therm (symbol thm) is a non-SI unit of heat energy equal to 100,000 British thermal units (BTU).The therm is equal to about 105.5 megajoules, 25,200 kilocalories or 29.3 kilowatt-hours.
The therm is a non-SI unit of heat energy equal to 100,000 BTU.
One therm is equal to 100,000 BTU's (100,000 British thermal units) and has nothing to do with volume measurement (cubic feet).
1 therm unit equals 100000 btu's
A BTU is the amount of heat required to raise the temperature of 1 pound (0.454 kg) of liquid water by 1 °F (0.56 °C)therefore = to about 1055 joules.
One million btu equals 10 therms. One hundred thousand btu equals one therm.
BTU should be a measure of heating content, so it will vary with composition. However, in the US, 1 cubic ft of natural gas = 1,028 BTU. 1 therm = 100,000 BTU 100 cf = 0.1 Mcf approximately 1 therm (th). or more exactly 0.0972 Mcf = 1 th. See natural gas under wikipedia.
Roughly 550.
1 Therm is 100,000 BTU, and as there are 1000 BTU in 1 cubic foot of gas, 1 Therm = 100 cubic feet. Density of methane = 0.72 kg/cubic meter which is 35.3 cubic feet, so 100 cubic feet = 2.04 kg
