Power Converter

Convert power units including watts, kilowatts, horsepower, and megawatts for electrical and mechanical systems.

About Power Converter

From solar panels (watts) to engines (horsepower) and industrial motors (kilowatts), power units abound. Tooloria’s Power Converter covers watts, kW, MW, hp (mechanical and metric) and BTU/h. A helper field calculates power from voltage and current with optional power-factor input. All maths run in your browser, so proprietary load profiles remain private.

Frequently Asked Questions

Is metric horsepower included?

Yes—choose ‘hp (metric)’; it equals 0.735 499 kW. The tool also has mechanical brake horsepower and boiler horsepower.

Can I calculate three-phase power?

Enable ‘three-phase’ mode, enter line-to-line voltage, current and power factor; the converter outputs kW, kVA and kVAR.

Are BTU/h accurate for HVAC sizing?

Yes—BTU/h uses ASHRAE definition (approximately 1 055.06 J). Toggle decimal places to match sizing charts.
