Result
Precision (significant figures)
Formula
kW = hp × 0.7457
1 hp = 0.7457 kW
All power converters
| Converter | Units | Typical use |
|---|---|---|
| Horsepower to Kilowatts | hp → kW | Engines, motors and pumps |
| Kilowatts to Horsepower | kW → hp | EV and car power ratings |
| BTU/h to kW | BTU/h → kW | Air conditioner and heater sizing |
| kW to BTU/h | kW → BTU/h | Comparing HVAC specs |
Common situations
Why people usually need a power conversion, and which tool answers it.
One unit is rated in BTU, another in kW.
You can’t compare them side by side. The risk: buying a unit that’s too small for the room.
An EV or European spec sheet lists power in kW, and you know horsepower.
There are two kinds of horsepower (hp and PS). The risk: comparing cars on the wrong numbers.
