The quantity of natural gas is usually expressed in cubic meters (m3). If you want to know much electricity will burning gas generate, you have to convert gas m3 into kWh (kilowatt-hours).
To help you out, we have created an m3 to kWh calculator. You simply input cubic meters (m3) and the calculator will dynamically convert m3 into kWh.
Here’s an example of what the m3 to kilowatt-hour conversion calculator looks like:
Below the calculator, you will also find the m3 to kWh conversion chart with calculated values of kWh for the corresponding m3 of natural gas.
Let’s first look at the equation that converts m3 of natural gas to kWh. The key thing to remember is that 1 m3 of natural gas doesn’t always generate the same amount of electricity (kWh).
That’s because the energy density of natural gas varies a bit depending on the quality of natural gas (some produce more kWh, others less kWh):

m3 To kWh Conversion Formula
Different qualities of natural gas have different energy densities. That’s why we use a bit more complex equation to convert m3 to kWh precisely:
m3 × Calorific Value × 1.02264 ÷ 3.6 = kWh
The caloric value of natural gas is the parameter that changes. It’s usually around 40.0; depending on the quality of natural gas it can deviate +/-5%. 1.02264 is a correction factor, and 3.6 is the conversion factor for kWh.
For extremely precise calculations, we would you the upper equation. However, without more than a 5% loss in accuracy, we can simplify it quite a bit.
If you want to convert m3 to kWh, you just need to use this simple formula:
1 m3 = 10.55 kWh
Before we use the calculator that converts m3 gas into kWh, let’s look at both quantities:
Cubic Meter or m3 (Volumetric Quantity Of Natural Gas)
Gasoline, diesel, and liquid propane are measured in liters (or gallons) because they are liquids. Natural gas, on the other hand, is a gas; in a gaseous state.
That’s why we use m3 of natural gas to tell how much natural gas we have. Cubic meters are a unit of volume.
1 m3 of natural gas is equal to:
- 35.315 cubic feet of natural gas.
- 35,300 BTU.
- 31,736 kJ.
- 7,580 kcal.
- 10.55 kWh.
Kilowatt-Hour Or kWh (Unit Of Electric Energy Per Hour)
Electric energy is measured in watts. 1000 watts is equal to 1 kW; kilowatt. If we run a 1,000W electric appliance for 1 hour, we spend 1 kWh of electricity. 1 kWh of electricity costs anywhere from 0.10€ (Bulgaria) to 0.30€ (Germany).
To generate 1 kWh of electricity, we have to combust 0.0947 m3 or 94.7 liters of natural gas (100% efficient combustion).
We can use this data to calculate how many kWh will burning any amount of natural gas (expressed in m3) generate:

You just insert m3 and the converter will dynamically calculate kWh. You can play around with the numbers a bit if you wish:
m3 Natural Gas To kWh Calculated Table
To help you out, we have used the calculator above to make some of the most common m3 to kWh conversion, and summarized them in the table here:

| 5 m3 gas | 52.75 kWh |
| 10 m3 gas | 105.50 kWh |
| 20 m3 gas | 211.00 kWh |
| 30 m3 gas | 316.50 kWh |
| 40 m3 gas | 422.00 kWh |
| 50 m3 gas | 527.50 kWh |
| 75 m3 gas | 791.25 kWh |
| 100 m3 gas | 1,055 kWh |
| 200 m3 gas | 2,110 kWh |
| 300 m3 gas | 3,165 kWh |
| 400 m3 gas | 4,220 kWh |
| 500 m3 gas | 5,275 kWh |
| 750 m3 gas | 7,912.50 kWh |
| 1,000 m3 gas | 10,550 kWh |
Hopefully, this will help you adequately determine the kWh value of natural gas. If you have any questions regarding the calculations, you can pose them in the comments below and we’ll try our best to help you out.
I am trying to convert 79.6 units used to kWh what is it and how do I calculate the cost?
Hello Nicola, you can get up to 839.78 kWh from 79.6 m3 of natural gas.
Simply divide or multiply by 10.55
You quote a formula , but based on the values you should be using in the formula , quoted lower down you page, the “simple conversion” should be 11.36 not 10.55 (1*1.02264*40/3.6 = 11.36) this is significantly more than your quoted 5% error (nearly 8% based on 11.36 and 10.55) however if the accepted figure for calorific value is 40 and it can vary from 38 to 42, then the error using your basic conversion factor is even greater at the extremes (11.9 @ 42 which is 13% error )
Why are you quoting 10.55 – makes no sense
Hello Roger, the 10.55 factor is a simple approximation. The actual formula is a more complex equation and the variables are difficult to pinpoint exactly. That’s why we make a rough estimation, but as you have adequately pointed out, this is not a 100% precise figure.
Hello my gas is 650m3 the The gas company calculated 7348.8kwh so is it wrong? How much should be accurate 650m3?
Hello Helen, gas companies have their own m3 to kWh calculation that factors in losses and some other factors. This m3 to kWh calculator calculates the hypothetical kWh you can get from natural gas at 100% efficiency. Hope this helps in understanding why there is a difference between what gas company calculates and what is the theoretical calculation.
Basic thing is …Multiply by 10.55 (and plus other factors)
So although energy companies are bound by the energy regulator price cap, they can tinker with this little equation as much as they like? How convenient.
And why, when you go to your energy supplier’s website and look at the conversion rate they have, why do they display it as the equation rather than the resulting value? Simple, to make it more complicated and difficult to understand.
Octopus Energy’s conversion rate is: 1.02264*39.9/3.6 which equals 11.33425
It takes 11.33425 units on my gas meter to make 1 KWh worth of gas.
Why not simply say that the conversion rate is 11.33425?
Bottom line, 11.33425 is much easier to understand and use to make a quick calculation than 1.02264*39.9/3.6.

Hi, it seems to me that when you wrote :
“1 m3 of natural gas is equal to:
35,315 cubic feet of natural gas.
35.300 BTU.” you have mixed up your decimal points and thousand separators.
Surely 1 cubic meter = 35.315 cubic feet.. Note the full stop, not the comma, i.e. “thirty-five point three one five”(NOT thirty-five thousand,three hundred and fifteen).
Similarly when you state that there are “35.300 BTU” in a cubic meter of natural gas you should have used a comma, not a full stop. There are of course 35,300 ( thirty- five thousand, three hundred) BTU in a cubic meter of N.G, not thirty-five point three zero zero. The use of a comma as a decimal point and a full stop as a “thousand separator” is accepted usage in many European languages but not in English.
Hello David, this is a fair point. We have corrected this thanks to your heads up. Hopefully, now the numbers are clearer to read.
Very useful information on converting cubic meter of gas usage into kwh
I had new meters installed and I was not told that old meters converts gas usage in cubic feet and new meter converts in cubic meters.
Hi if my last reading was 00503.761m3 and my new one is 00522.237m3 how much will that be in kWh thanks
Hello Heleen, you just look at the difference here: 18.474m3. You have basically burned about 3.7% more than in your previous reading. In terms of kW, you have used about 195 kW worth of natural gas. Hope this helps.
