What is the power converter?

The power converter is a collection of calculators for changing one power unit into another. Convert power units for engines, motors, appliances, HVAC systems, electricity, and mechanical output.

Power conversions help compare engines, electric motors, appliances, HVAC systems, generators, and mechanical output ratings.

Available power units

Common power use cases

Use this category when the same measurement appears in different unit systems, data sheets, calculators, reports, or regional conventions.

Professional power guidance

These notes are written for the highest-traffic power pages, where users often need more than a raw number.

Power is a rate, not stored energy

Watts, kilowatts, horsepower, and BTU per hour describe how quickly energy is transferred or used. They should not be confused with energy units such as joules, watt-hours, or kilowatt-hours.

Rating context changes interpretation

A motor, engine, appliance, generator, or HVAC device may list input power, output power, peak power, or continuous power. Unit conversion does not explain which rating type the source uses, so keep the rating label with the converted result.

These short unit notes help readers choose the right starting unit before opening a specific conversion page.

Watt (W)

A watt is the SI unit of power. It measures the rate at which energy is used, produced, or transferred.

Browse watts conversions

Kilowatt (kW)

A kilowatt is equal to 1,000 watts. It is used for appliances, motors, generators, vehicle charging, and electrical systems.

Browse kilowatts conversions

Megawatt (MW)

A megawatt is equal to one million watts. It is commonly used for power plants, grid capacity, and large industrial systems.

Browse megawatts conversions

Horsepower (hp)

Horsepower is a power unit commonly used for engines, motors, vehicles, pumps, and mechanical output ratings.

How power conversion works

Power conversions use a standard reference unit as the bridge between source and target units, so each page can show both the direct formula and practical examples.

How to use this converter

Enter a value, choose the units, and read the converted result immediately. Each dedicated conversion page also includes a formula, examples, a conversion table, related links, and FAQ.

FAQ

Which power units are included?

This category includes watts, kilowatts, megawatts, horsepower, BTU per hour and related units.

Are formulas included?

Yes. Individual conversion pages include formulas, manual steps, examples, and conversion tables.

Is kilowatt the same as kilowatt-hour?

No. Kilowatt is power, a rate of energy transfer. Kilowatt-hour is energy accumulated over time.

Why do horsepower and kilowatts both appear on equipment?

Horsepower is familiar for engines and machinery, while kilowatts are common in SI and electrical specifications. Converting helps compare the same power rating across markets.
