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. If you would like to change the rate used in the calculations above, enter a new rate below.

Gas calculator - equation

Cost to operate = usage (hours or load) x (BTUs/100,000) x price per therm
OR
Cost to Operate = usage (hours or load) x therms x price per therm

Conversion table

• 1 BTU = 0.293 watt hours
• 100,000 BTU = 1 therm
• 3,413 BTU = 1 kilowatt hour
