What the animation shows
The animation and the step-by-step video above use your numbers. Here is the same walkthrough written out for the default example.
What you enter
- Capacity: 12000 BTU/h.
What happens, step by step
- The heat source puts out 12,000 BTU/h, shown as the red bar.
- Three dials read the same heat in BTU per hour, kilowatts and tons.
- One ton is the cooling of one ton of ice melting in a day.
- So 12,000 BTU/h equals 3.517 kW, or 1 ton of cooling.
The answer: btu/h is 12,000 BTU/h.
How it’s calculated
- 1 BTU/h = 0.29307 W
- 1 ton = 12,000 BTU/h = 3.5169 kW
Worked example
12,000 BTU/h (one ton).

Questions
How many kW is 12,000 BTU?
12,000 BTU/h equals about 3.52 kW, or one ton of cooling.
Why is it called a ton?
It is the cooling from melting one short ton of ice over 24 hours.
