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):
