Power Converter
Convert watts, kilowatts, megawatts, milliwatts, horsepower, BTU per hour, and foot-pounds per second with a browser-local power converter.
Client-side only: the conversion runs in your browser. Values are not uploaded, stored, fetched, or logged.
Base unit: watt. Useful for equipment specs, electrical notes, motor ratings, appliance comparisons, and documentation.
Power Converter workflow tips
Use this converter when an appliance spec, equipment note, motor rating, or technical document mixes watts, kilowatts, horsepower, and BTU per hour.
Normalize power ratings
Convert the power rating here, then use Energy Converter, Pressure Converter, or Data Storage Converter when the same workflow needs adjacent values.
Prepare clean copy
After converting values, use Prefix / Suffix Lines or Find and Replace Text to format measurement lists.
Keep it browser-local
The calculation happens in your browser only. No accounts, uploads, storage, or server-side processing are used.
