## Quick Answer

Convert power measurements between scientific, mechanical, and electrical units. Enter your power value and select units to calculate conversions across watts, horsepower, and BTUs.

## Definition

A power converter is a scientific measurement utility that translates power values between different metric, mechanical, and thermal units. This one supports six: watts (W), kilowatts (kW), megawatts (MW), mechanical horsepower (hp), British thermal units per hour (BTU/h), and foot-pounds per second (ft·lb/s). There is one horsepower here and it is the mechanical one, defined as 550 foot-pounds per second. Every pair is converted through the watt, and the three factors that are not powers of ten are derived from their defining values rather than typed in rounded. Engineering students, electricians, automotive technicians, and HVAC specialists use this tool to standardize rate-of-work measurements across different systems.

## How to Use

1. **Enter power value** — Type the numerical power or rate of work value you want to convert.
2. **Select original unit** — Choose the measurement unit you are starting with from the dropdown options.
3. **Read converted powers** — View the equivalent power across watts, kilowatts, horsepower, and thermal units.
