BTU Per Hour Converters

Convert BTU per hour to watts, kilowatts, horsepower, tons of refrigeration and other power units.

What this tool does

Convert BTU per hour to watts, kilowatts, horsepower, tons of refrigeration and other power units. Type an amount in BTU (International Table) per hour, choose the units, and the tool converts it to watts. It offers 15 power units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 15 options, including BTU (International Table) per hour, BTU (International Table) per minute, BTU (International Table) per second, BTU (thermochemical) per hour, Watt, Kilowatt. Starts as BTU (International Table) per hour.
  • To: Choose one of the same 15 units as "From". Starts as Watt.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from BTU (International Table) per hour to watts:

  • 1 BTU/h ≈ 0.293071 W
  • 5 BTU/h ≈ 1.465355 W
  • 10 BTU/h ≈ 2.930711 W
  • 50 BTU/h ≈ 14.653554 W
  • 100 BTU/h ≈ 29.307107 W

Multiply the number of BTU (International Table) per hour by about 0.293071 to get watts. The factor follows from exact definitions. It has more digits than fit here, so it is shown rounded.

Limitations

  • Converts units of power only. It does not size a heater or air conditioner for a room.
  • BTU here means the International Table BTU unless the label says thermochemical.
  • Calories per second are thermochemical calories; kilocalories per hour are International Table.

FAQs

Q: How many watts is one BTU per hour?
A: One BTU per hour (International Table) is about 0.2931 watt. Multiply BTU/h by 0.2931 for watts, or divide watts by 0.2931 for BTU/h.
Q: Which BTU does this page use?
A: The International Table BTU (about 1,055.06 joules). The thermochemical BTU per hour is also listed and is very slightly smaller.
Q: What is a ton of refrigeration?
A: A ton of refrigeration is 12,000 BTU (International Table) per hour, about 3.517 kW. It is a unit of cooling capacity, not of weight.
Q: Can I convert watts to BTU per hour?
A: Yes. Choose watt in the From box and BTU/h in the To box.
