BTU/hr to Watts Converter
Convert HVAC capacity from BTU per hour to watts in a single step. This tool multiplies your BTU/h rating by 0.29307107 so you can compare air conditioners, heat pumps, and heaters that list wattage or kilowatt requirements.
Energy conversion only; efficiency losses are not included.
Examples
- A 12,000 BTU/h window AC uses approximately 3,516.85 watts of cooling power.
- A 36,000 BTU/h mini-split system converts to 10,550.56 watts.
- A commercial furnace rated at 80,000 BTU/h equals 23,445.69 watts.
FAQ
What is a BTU per hour?
It represents the rate of energy transfer needed to heat one pound of water by one degree Fahrenheit in one hour.
How do I convert watts back to BTU/hr?
Divide watts by 0.29307107 to obtain BTU/hr.
Does this account for equipment efficiency?
No, the conversion is purely between units and ignores system losses.
Why would I need watts instead of BTU/hr?
Electrical circuits, generators, and solar systems are usually sized in watts or kilowatts. Converting BTU/hr to watts helps you verify that the equipment will not overload the power supply.
Additional Information
- Watts (W) measure power in the International System of Units and indicate how quickly energy is used or produced.
- Many HVAC specifications list BTU/h for heating and cooling output; multiplying by 0.29307107 converts to watts.
- To express the result in kilowatts, divide the watts value by 1,000 after conversion.
