BHP to kilowatts calculator
Convert brake horsepower (bhp) to kilowatts (kW) and back. Uses 1 bhp = 0.7457 kW for precise motor and engine power conversions.
mechanical horsepower to kW
Immediately change brake horsepower to kilowatts: kW = bhp 0.7457. In the case of reverse, bhp = kW / 0.7457. This exact conversion makes the engine and motor ratings agree with the SI units.
Formula & Table Summary:
bhp → kW: kW = bhp × 0.7457
kW → bhp: bhp = kW ÷ 0.7457
(Engineering round: 1 bhp ≈ 0.746 kW)
brake horsepower to kW
The BHP to Kilowatts Calculator is used to convert brake horsepower (bhp) which is a widespread measurement of engine and motor power into kilowatts (kW), the SI unit of power. As a definition, 1 bhp = 0.7457 kW (usually approximated to 0.746 kW on datasheets). Reverse conversion will be 0.7457 1/ kW = bhp. Such conversions become necessary in comparing international specs, in sizing drives, electrical demand estimation, or conversion of automotive values to industrial values. The tool enables engineers, technicians, and students to prevent sizing errors and reliability in the power reporting of various regions and consistency. Using precise bhp↔kW conversion, you can ensure the selection of a pump motor, generator outputs, car engine ratings and many more projects remain on spec and within budget.

Frequently Asked Questions - BHP to kilowatts calculator:
What is the bhp to kW formula?
kW = bhp × 0.7457 (≈0.746).
How do I convert kW to bhp?
bhp = kW ÷ 0.7457.
Is bhp the same as mechanical horsepower?
Yes, bhp is commonly treated as mechanical horsepower for conversions.
Why do some sources use 0.746 kW per bhp?
0.746 is a rounded engineering value; 0.7457 is more precise.
Does efficiency affect the conversion?
No—unit conversion is independent of efficiency, which affects required input power.
Can I use this for car engines?
Yes, automotive bhp converts to kW using the same constant.
What about metric horsepower (PS)?
Metric hp uses 1 PS = 0.7355 kW; different from bhp.
Are kW and kVA the same?
No. kW is real power; kVA is apparent power (kW = kVA × PF).
Is hp (US) different from bhp?
Bhp typically refers to mechanical horsepower measured at the shaft; both use 0.7457 kW per hp.
How accurate is the conversion?
Exact by definition using 0.7457; minor rounding may be used in practice.
