How much electricity do we get out of natural gas? This is the classic case when we would need to convert therms of natural gas to kWh (kilowatt-hours) of electricity. To help you out with this conversion, we have created Therms To kWh Calculator, complete with Therms To kWh Conversion Chart (we have converted 0.1 to 1000 therms to kWh and summarized the results in the chart).
Let’s first look at the units we are converting:
- Therm is a unit of heat content, primarily used for natural gas. 1 therm is equal to 100,000 BTU (source). BTU or British Thermal Unit is the amount of energy needed to increase the temperature of 1 pound of water by 1 degree Fahrenheit. Thus 1 therm is the energy needed to increase the temperature of 100,000 pounds of water by 1°F.
- kWh of kiloWatt-hour is a unit of electric energy. 1 kWh is equal to 1 kW or a 1000-watt electric device running for 1 hour.
With the therms to kWh conversion, we are actually asking how many kWh of electricity we can get from burning X therms of gas. We predispose that the burning of gas is a 100% efficient process; 100% of the energy generated by burning gas is turned into electricity (measured in kWh). Here are two pieces of information we need to make this conversion:
If 1 therm is equal to 100,000 BTU and 1 BTU is equal to 0.00029308323 kWh, then 1 therm (or 100,000 BTU) is equal to:
1 therm = 100,000 BTU × 0.00029308323 kWh/BTU = 29.308323 kWh
As we can see, 1 therms is equal to 29.308323 kWh. That means that the therms to kWh formula looks like this:
kWh = Therms × 29.308323 kWh Per Therm
Quick Example: How many kWh of electricity do we get if we burn 50 therms of gas? We just use this equation and calculate the generated kilowatt-hours: like this:
kWh (50 Therms) = 50 Therms × 29.308323 kWh Per Therm = 1,465.42 kWh
As you can see, 50 therms is equal to 1,465.42 kWh. This is just one example.
You can use the following Therms To kWh Calculator to make this conversion (just insert therms, and you will get kWh). Below the calculator, you will also 0.1 therms to 1000 therms converted into kWh and summarized in a neat conversion chart:
Therms To kWh Calculator
Here is how easy it is to use this calculator:
Let’s say you want to convert 100 therms to kWh. Just slide the slider to ‘100’ and the calculator will give you the result automatically: 100 therms is equal to 2,930.83 kWh.
Here is the conversion chart to help you out as well:

| 150 Therms | 4,396.25 kWh |
| 200 Therms | 5,861.66 kWh |
| 250 Therms | 7,327.08 kWh |
| 300 Therms | 8,792.50 kWh |
| 400 Therms | 11,723.33 kWh |
| 500 Therms | 14,654.16 kWh |
| 1000 Therms | 29,308.32 kWh |
If you need to convert therms of natural gas to kWh of electricity, you can now just consult this chart.
Example: How many kWh is 250 therms? You can read that off the chart: 250 therms is equal to 7,327.08 kWh.
It needs to be said that no power plant can convert therms of gas into electricity with 100% efficiency. The efficiencies range from as low as 20% to as high as 98%.
Hopefully, now you have a good understanding how to make the therms to kWh conversion. If you need any help with the conversion, you can use the comment section below, give us some numbers, and we will help you out.
Thank you.
