Power Converter — W, kW, MW, hp (metric & mechanical), BTU/h

Easiest Converter’s power converter gives fast, accurate conversions for electrical and mechanical work, HVAC sizing, automotive specs, and equipment datasheets. Convert between watt (W), kilowatt (kW), megawatt (MW), horsepower metric hp(m), horsepower mechanical hp(i), and BTU per hour (BTU/h) with clean, readable output you can copy in a click.

Calculations reference the watt, keeping math consistent across systems. Popular pairs include kW ⇄ hp for motors and vehicles, kW ⇄ BTU/h for heating/cooling capacity, and W ⇄ kW for appliance and inverter ratings. Use hp(i) for US mechanical horsepower and hp(m) for metric specifications.

Why this power converter? The interface is tuned for clarity—keyboard-friendly inputs, a one-tap swap, and a copy-to-clipboard result string. Numbers use sensible precision so values stay readable while remaining accurate for proposals, reports, and field notes.

Supported units: W, kW, MW, hp(m), hp(i), BTU/h. Whether you’re comparing motor nameplates, sizing HVAC equipment, or translating datasheets, this tool keeps your conversions fast, consistent, and easy to share.

• Use ⇄ to swap “From” and “To” instantly.
• Click 📋 to copy a neat result string for notes or emails.
