How do you convert therms to cubic meters?

Answer 1

The "therm" is a unit of energy often used in connection with various methods

of home heating ... gas, oil, electric, etc.

1 therm = 100,000 BTU = 1.055 x 108 joules

That's the easy part. The next question is: How much energy do you get

by burning a cubic meter of natural gas ? The references we found on line

listed the following answers (in mega-joules):

37, 40, 37, 19 to 56, 37 to 41, 39, 38.

Instead of agonizing over which one is correct, let's say there's a grain of truth

in all of them, and take an average ... 38.21 megajoules per cubic meter. OK.

Now we're ready to do the conversion for you:

(1 therm/1.055 x 108 joule) x ( 38.21 x 106 Joule/cubic meter) =

0.362 therm/cubic meter

2.761 cubic meter/therm.

Your answer is:

Multiply therms by 2.761 to find out how many cubic meters of gas

you need to burn in order to produce that much heat.
