Therms To kBTU Calculator: Convert Therms To kBTU (Heating)

In HVAC (mostly heating), you may need to convert therms to kBTU. Basically, we are converting 100,000 BTUs (therms) to 1,000 BTUs (kBTU or kilo British Thermal Units). This is a simple calculation; to simplify it even more, we created an online Therms to kBTU Calculator (insert therms, get kBTU right away).

On top of that, we also converted 0.1-1000 therms to kBTU, and summarized the results in a conversion chart for quick use (after this calculator):

Here’s how this calculator works:

Let’s say you want to convert 200 therms to kBTU. You just insert ‘200’ in the therms input field, hit ‘Calculate’, and get this result immediately (screenshot):

You can see right away that 200 therms is equal to 20,000 kBTU.

Let’s have a look at the math behind this conversion (super easy):

Therms To kBTU Formula

We use both of these units to denote heat energy. Here is how they are defined:

  • Therm is heat energy equal to 100,000 BTUs (British Thermal Units). 1 BTU is the energy needed to increase the temperature of 1 pound of water by 1°F.
  • kBTU stands for kilo British Thermal Units. 1 kBTU is the heat energy equal to 1,000 BTUs.

From these descriptions, we can see the following relationship between the two units:

1 Therm = 100 kBTU

Basically, 1 therm is equal to 100 kBTU. That makes the conversion super easy. We can use this therms to kBTU formula:

kBTU = Therms × 100

Namely, to calculate therms from kBTU, we need to multiply therms by a factor of 100.

Quick Example: How many kBTU is 50 therms of heat energy? Let’s just insert 50 therms into the equation like this:

kBTU (50 Therms) = 50 Therms × 100 = 5,000 kBTU

We see that 50 therms is equivalent to 5,000 kBTU. You can use the calculator above to check this result.

If you need a very quick conversion, you can just consult this conversion chart, ranging from 0.01 therms to 1000 therms (converted to 1 kBTU to 100,000 kBTU, respectively):
