Power Converter
Convert between watts, kilowatts, horsepower, and BTU per hour.
Vehicle and engine specifications are usually quoted in horsepower, electrical appliances in watts or kilowatts, and HVAC equipment often in BTU per hour — three different unit families for the same underlying physical quantity, power, making cross-comparison a common need.
This converter handles watts, kilowatts, horsepower, and BTU/hour with precise conversion factors, useful for comparing an engine's horsepower rating to its kilowatt equivalent, sizing electrical equipment, or understanding an air conditioner's BTU rating in more familiar wattage terms.

Frequently asked questions
Common mistakes to avoid

- Mixing up power (rate of energy use, watts) with energy (total amount used, watt-hours) — see the Energy Converter for the latter.
