# How do you calculate metric brake horsepower?

## How do you calculate metric brake horsepower?

Formula for calculations of Break horsepower is

- BHP = (Torque × RPM )/5252,where torque is lb -ft and n = revolution per min.
- BHP = BP /33000,where BP (in watt ) = Torque×2π×RPM (RPM in min. ) Where torque in the formula of BP is in lb -ft.
- BHP =BP (in Watt ) / 746 we get it in horse power ,since 1 HP = 746 watt.

**How do you convert HP to BHP?**

The Boiler horsepower unit number 0.075 bhp converts to 1 hp, one horsepower – Metric. It is the EQUAL power value of 1 horsepower – Metric but in the Boiler horsepower power unit alternative.

### What is the metric conversion for horsepower?

The electrical equivalent of one horsepower is 746 watts in the International System of Units (SI), and the heat equivalent is 2,545 BTU (British Thermal Units) per hour. Another unit of power is the metric horsepower, which equals 4,500 kilogram-metres per minute (32,549 foot-pounds per minute), or 0.9863 horsepower.

**Is BHP the same as HP?**

HP vs BHP. Traditionally ‘brake horsepower’ (bhp) has been used as the definitive measurement of engine power. It’s distinct from horsepower because it takes into account power loss due to friction – it’s measured by running an engine up to full revs, then letting it naturally slow down to a dead stop.

#### What is the formula of IHP?

For an internal-combustion engine, the mechanical efficiency e = bhp/ihp, where ihp = indicated horsepower. Thus, ihp = bhp/em, or ihp = 500/0.85 = 588 ihp (438.6 kW).

**Why is horsepower called horsepower?**

James Watt, who invented steam engines, figured out a mathematical way to equate horses to engine power. Thus the term horsepower was invented. Watt measured the capability of a big horse to pull a load and found it could pull a weight of 150-pounds while walking at 2.5 miles per hour.

## Is British horsepower the same as American horsepower?

1 Imperial unit of horsepower = 1.014 Metric – a small but not insignificant difference.. dchalifo: This conversion factor doesn’t work. The Mazda RX8 is listed at 231 hp in UK and as 238 hp in America. The conversion factor to “metric” does not account for how and where the power is measured.
