Power converter
ConvertersNo. 11 / 24approved
One value, every power — milliwatts, watts, kilowatts, megawatts, gigawatts, horsepower and BTU/h. From the bulb to the power plant, at once.
1 hp ≈ 1.014 PS — the European horse is slightly stronger.

most-used utilities
Light bulb
60 watts of vintage lighting, now illegal in polite kitchens.
Hairdryer
1500 W of getting ready, 90 seconds at a time.
Household hum
1 kW. The ambient hum of a whole house pretending to be busy.
Sports car
500 hp. The engine's way of saying "you won't use it, but it's there".
Electric car
150 kW of instant torque and quiet smugness.
Power plant
500 MW. Enough to run a small city and several gaming setups.
pro tips
1 horsepower is 745.7 watts — a horse doing a well-documented amount of work, continuously, for the science.
PS and hp are the same idea with different accents: 1 hp ≈ 1.014 PS. The European horse is slightly stronger.
Rough math: 1 kW ≈ 1.34 hp. Your car's engine and your kettle are separated by a comma.
what it does
Type a number, pick its unit, and every other power unit updates at the same time. Milliwatts, watts, kilowatts, megawatts, gigawatts, horsepower and BTU/h — the whole grid in one screen.
The conversion runs through watts, the unit the physics people quietly agree on. Click any result to copy that particular value, because someone will always ask for the number in horsepower.
Handy for appliances, cars, electronics and the eternal "how many horsepower is that, in kettles?" — the unit that unites engineers and toast-lovers.
Use it when a kettle says 2 kW and you want to feel superior in horsepower, when a spec sheet quotes watts but your brain works in kilowatts, or when a sports car brags in PS and your country thinks in hp. One value, every unit at once — click any result to copy it and get back to the toast.
quick answers
How do you convert kW to horsepower?
Multiply by 1.341. The widget shows it, plus PS and watts, all in one screen.
What's the difference between hp and PS?
They're both horsepower with different accents — 1 hp ≈ 1.014 PS. The European horse is slightly stronger, and the bragging rights are louder.
Why is a kilowatt a useful unit?
Because appliances, electric cars and power bills all speak in kW — and your kettle is quietly a 2 kW athlete.
What is BTU/h?
British Thermal Units per hour — how air conditioners and heaters rate themselves. It converts to watts too, so you can compare a heater to a kettle without a translator.
