Natural gas is measured in therms or BTUs. 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. The current charge
for natural gas from We Energies
is $0.4651 per therm.

Gas calculator - equation
Cost to operate = usage (hours or load) x (BTUs/100,000) x price per therm
Cost to Operate = usage (hours or load) x therms x price per therm
- 1 BTU = 0.293 watt hours
- 100,000 BTU = 1 therm
- 3,413 BTU = 1 kilowatt hour
