About this calculator
EV output is quoted in kW in Europe and hp in the US. Enter a value in kilowatts and this converter returns horsepower along with the reverse direction, so you can sanity-check either way without re-typing.
Worked example
Using the values the calculator loads with:

FAQ
How does the kilowatts to horsepower converter work?
EV output is quoted in kW in Europe and hp in the US. Enter a value in kilowatts and this converter returns horsepower along with the reverse direction, so you can sanity-check either way without re-typing. The underlying maths is: Horsepower = Kilowatts × 1.34102209
What do I need to enter?
Just one value: value in kilowatts. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the horsepower (hp) result mean?
It is returned as a decimal number and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
Is this calculator free, and do I need an account?
Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser.
How accurate is the result?
It applies the standard formula exactly, so the arithmetic is precise. Estimates assume standard, average conditions — local rules, pricing, and materials vary.
Who is this tool for?
It's built for anyone doing everyday planning maths — a quick estimate that would otherwise need four browser tabs and a calculator app.
Accuracy and limitations
- Estimates assume standard, average conditions — local rules, pricing, and materials vary.
- Results are rounded for readability; add a buffer before ordering, booking, or committing.
- Double-check anything with a real cost attached against a local quote.
