About Energy & Power Conversions

Energy conversions span from scientific units like joules and electronvolts to practical everyday units like kilocalories (food energy) and kilowatt-hours (electricity bills). The BTU converter is commonly used in HVAC and heating applications.

Power conversions help you compare motors and engines rated in watts, kilowatts, and horsepower. Fuel consumption conversions between km/L, L/100km, and mpg are invaluable when comparing vehicle efficiency across regions that use different standards.
