About this calculator
Power conversion is useful in appliances, generators, engines, and HVAC equipment because product specifications often mix electrical and mechanical power units.
A good converter should include both consumer-friendly and engineering-friendly units so the page works across home, trade, and technical use cases.
Frequently asked questions
Why are horsepower and kilowatts both common?
Because different industries and product categories historically adopted different power units for similar equipment.
What is BTU per hour used for?
It is commonly used to describe heating and cooling capacity in HVAC contexts.
Should I compare power and energy directly?
No. Power describes rate, while energy includes time and is measured in different units such as kilowatt-hours or joules.
