kW to BHP Conversion Calculator

hp



kW to BHP (Brake Horsepower) calculator converts power measurements between kilowatts (kW) (metric system) and brake horsepower (BHP) (imperial system). This conversion is essential in automotive, mechanical engineering, and industrial applications where engine and motor power outputs are compared.

Key Definitions

  • Kilowatt (kW) – Metric unit of power (1 kW = 1,000 W).

  • Brake Horsepower (BHP) – Measure of an engine's power before losses (1 BHP ≈ 0.7457 kW).


Conversion Formulas

1. kW to BHP

P(BHP)=P(kW)×1.34102

Example:

  • Convert 100 kW to BHP:

    100×1.34102=134.102 BHP

2. BHP to kW

P(kW)=P(BHP)×0.7457

Example:

  • Convert 150 BHP to kW:

    150×0.7457=111.855 kW

How to Use the Calculator

  1. Enter kW → Get BHP (Multiply by 1.34102).

  2. Enter BHP → Get kW (Multiply by 0.7457).

Example Calculations:

  • 75 kW to BHP:

    75×1.34102100.58 BHP
  • 250 BHP to kW:

    250×0.7457186.43 kW

FAQ

1. What is the difference between BHP and HP?

🔹 BHP (Brake Horsepower) measures power at the engine's output shaft (before drivetrain losses).
🔹 HP (Horsepower) is a general term for power, sometimes including drivetrain losses.

2. How many BHP is 1 kW?

✅ 1 kW ≈ 1.341 BHP

3. Why do European cars use kW instead of BHP?

🔹 Metric system standard (kW is the SI unit for power).

4. Is BHP higher than kW?

🔹 Yes, because 1 kW = 1.341 BHP.

5. How to convert 300 kW to BHP?
