It’s very simple to convert kW to BTU or BTU to kW – especially with our calculators below.
Simply enter your starting value into the first field and it will give you the resulting BTU or kW value.
Find out how to make the kW and BTU conversion calculations yourself below!
KW To BTU Conversion
If you would like to get out your calculator and do the sum yourself, here’s all you need to do.
kW x 3412.142
1 kW = 3412.142 BTUs
You see, it’s super simple!
Many people want to answer this question because they are looking to buy an electric fireplace or other heating devices.
Electric heaters are usually sold as ‘2.3 kW’ (or whatever they actually are) but many like to know the BTU value as well.
Sometimes your heater will be sold in watts but this is another easy calculation – 1000 watts = 1 kW.
A 2300-watt heater is 2.3 kW.
BTU to kW Conversion
Again, it’s a simple calculation to find out the kW value.
BTU x 0.00029307107
1 BTU = 0.00029307107 kWs
It’s not a formula you can memorize and do in your head, but easy enough on most calculators – and even easier with our BTU to kW calculator above.
Kilowatts Vs British Thermal Units
A kilowatt is a measure of power.
A BTU is the amount of energy it takes to increase the temperature of a pound of water 1° F.
Sometimes retailers will give their heating device specs with both measurements. Dwarf Tiny Wood Stoves do this, for example, for their mini wood stoves.
Mostly, however, electric devices will be measures in kW (or watts) and gas or wood burning appliances will be shown in BTUs.
Thankfully, the BTU conversion to kilowatts and the kW conversion to BTU is super easy for those who want to do it!
Now you know how to convert kW to BTU, but let us know if you have any questions down below.
