In HVAC (heating/cooling), we may have to convert kWh to kBTU. This is to say, we are converting * kilowatt-hours* (

**kWh**) to

*(*

**k**ilo**B**ritish**T**hermal**U**nits**kBTU**). Since this is not a conversion you can easily do in your head, we prepared an online

**kWh to kBTU calculator**you can freely use (

*insert kWh, get kBTU*right away).

On top of that, we also converted **0.001-1000 kWh into kBTU**, and created a neat *conversion chart* (here you can just read of the kWh-kBTU equivalents). Let’s start with the calculator, followed by the explanation and the conversion chart:

Here is how this calculator works:

Say you want to convert 5.5 kWh to kBTU. You just insert **‘5.5’** in the kWh input field, hit *‘Calculate’*, and you get the result in this form (screenshot):

You can see right away that 5.5 kWh is equal to **18.767 kBTU** (that’s 18,767 BTUs). If you need this conversion in reverse – kBTU to kWh – you can check a similar kBTU to kWh calculator here.

Let’s look at both of these units and the relationship between them:

### kWh To kBTU Formula

Both of these units in HVAC denote heating or cooling capacity. Here is what they stand for and definitions:

**kWh**stands for kilowatt-hours. In general, we use it to denote electricity expenditure. In HVAC, however, we also use it to denote the capacity of air conditioners, furnaces, and so on*(used in Europe and internationally)*. 1 kWh is equal to roughly 3412 BTU.**kBTU**stands for kilo British Thermal Units*(used in the US, UK, Australia)*. 1 kBTU is thus equal to 1000 BTU.

Here is the precise relationship between these two HVAC units:

**1 kWh = 3.41214163312794 kBTU**

We usually say that 1 kWh is equal to about 3.412 kWh (of that 3 kWh is equal to very roughly about 10 kBTU). Here is the exact kWh to kBTU formula:

**kBTU = kWh Ã— 3.41214163312794**

Namely, to convert kWh to kBTU, we need to multiply kWh by a factor of 3.41214163312794 (more decimal numbers = higher accuracy).

Quick Example: *How many kBTU is 3.5 kWh?* Let’s insert 3.5 kWh in the equation above like this:

kBTU (3.5 kWh) = *3.5 kWh* Ã— 3.41214163312794 = **11.942 kBTU**

We see that 3.5 kWh in HVAC is equivalent to 1**1.942 kBTU** (about 12 kBTU).

Inserting all these digits in a hand calculator is a bit tedious. That’s why the calculator above is so useful. On top of that, we created this 0.001-1000 kWh to kBTU chart you can use for quick conversions:
