How to Convert HP to kW
You can manually convert horsepower to kilowatts using a simple formula. Horsepower is a measurement of power commonly used in mechanical systems, while Kilowatts are part of the International System of Units (SI).
Formula
Step-by-Step Example
Let’s convert 10 HP to kW:
Step 1: Write the formula
kW = HP × 0.746
Step 2: Insert the value
kW = 10 × 0.746
Step 3: Calculate
kW = 7.46
Step 4: Final Answer
10 HP = 7.46 kW
Quick Notes
- 1 horsepower equals approximately 0.746 kilowatts.
- This conversion works for mechanical and electrical horsepower.
