If you use electric heating (electric furnaces, electric water heaters), you will naturally want to convert kWh to therms. We will show you exactly how to do it. On top of that, you have an easy-to-use kWh To Therms Calculator further on (just insert kWh, get therms). To top it off, we have converted 1 to 10,000 kWh into therms and summarized the results in the chart below.
Converting electrical energy (kWh) into heating output (therms) starts by understanding both of these units:
- kWh stands for kiloWatt-hour. This is a unit of electric energy equal to 1,000-watt unit running for 1 hour (1 kW, 1 hour = 1 kWh).
- Therm is a unit for heating capacity (or heat content). 1 therm is equal to 100,000 BTU. BTU, as we know, stands for British Thermal Unit. If we were to heat up 1 pound of water by 1 degree Fahrenheit, we would need to use 1 BTU.
Electricity is usually converted into heat with 100% efficiency (all kWh are used to produce therms). We know that 1 kWh is equal to 3,412 BTU. Now, therm = 100,000 BTU. That means that we can write the kWh to therms conversion formula like this:
Therms = kWh × 0.03412956
Example: Let’s say we want to figure out how many therms is 1 kWh. We just input 1 kWh into this equation like this:
Therms (1 kWh) = 1 × 0.03412956 = 0.03412956 Therms
As we can see, 1 kWh is equal to about 0.034 therms. Inversely, we need to use 29.30 kWh of electricity to get 1 therm of heating output.
Multiplying kWh by 0.03412956 to get therms can be quite a bother. That’s why we have created the following kWh To Therms Calculator that does this calculation automatically. Below the calculator, you will also find a kWh to therms conversion chart you can freely use:

Here is how this calculator works:
Let’s say you have spent 147 kWh of electricity on heating. How many therms did these 147 kWh generate? Just slide the slider to ‘147’ and you get the result: 147 kWh is equal to 5.02 therms.
For full results, let’s have a look at the conversion chart:

| 1 kWh | 0.0341 Therms |
| 5 kWh | 0.171 Therms |
| 10 kWh | 0.34 Therms |
| 20 kWh | 0.68 Therms |
| 30 kWh | 1.02 Therms |
| 40 kWh | 1.37 Therms |
| 50 kWh | 1.71 Therms |
| 60 kWh | 2.05 Therms |
| 70 kWh | 2.39 Therms |
| 80 kWh | 2.73 Therms |
| 90 kWh | 3.07 Therms |
| 100 kWh | 3.41 Therms |
| 150 kWh | 5.12 Therms |
| 200 kWh | 6.83 Therms |
| 250 kWh | 8.53 Therms |
| 300 kWh | 10.24 Therms |
| 350 kWh | 11.95 Therms |
| 400 kWh | 13.65 Therms |
| 450 kWh | 15.36 Therms |
| 500 kWh | 17.06 Therms |
| 600 kWh | 20.48 Therms |
| 700 kWh | 23.89 Therms |
| 800 kWh | 27.30 Therms |
| 900 kWh | 30.72 Therms |
| 1,000 kWh | 34.13 Therms |
| 2,000 kWh | 68.26 Therms |
| 5,000 kWh | 170.65 Therms |
| 10,000 kWh | 341.30 Therms |
Now you can easily read the kWh to therms conversion from this chart.
Example: How many therms is 300 kWh? Just check the chart, and you can see the result: 300 kWh is equal to 10.24 therms.
With the kilowatt-hour to therms calculator and chart, you can now easily figure out how many therms do you generate with a given kWh electricity usage. If you need any help, you can use the comment section below, give us some numbers, and we will help you out.
