Horsepower (British) to Watts conversion

How to convert horsepower (british) to watts?

Sure, let's go through the conversion of 1 Horsepower (British) to Watts, and provide some real-world examples.

Conversion

1 Horsepower (British), often abbreviated as HP, is defined as 550 foot-pounds per second. The equivalent in the SI unit system (Watts) is: $1 \text{ HP} = 745.7 \text{ Watts}$

The conversion factor is therefore: $1 \text { HP (British)} = 745.7 \text{ W}$

Real-World Examples

1. Lawn Mowers:

   • Small residential lawn mowers typically have engines rated at around 3 to 5 HP. In watts, this is approximately: $3 \text { HP} = 3 \times 745.7 \text{ W} = 2237.1 \text{ W}$ $5 \text { HP} = 5 \times 745.7 \text{ W} = 3728.5 \text{ W}$

2. Cars:

   • A typical small car engine might have a power output of around 120 HP. $120 \text{ HP} = 120 \times 745.7 \text{ W} = 89484 \text{ W}$
     • That’s 89.484 kilowatts (kW).

3. Motorcycles:

   • A performance-oriented motorcycle engine might produce around 150 HP. $150 \text{ HP} = 150 \times 745.7 \text{ W} = 111855 \text{ W}$
     • That’s approximately 111.855 kW.

4. Industrial Electric Motors:

   • Large industrial electric motors might be rated at around 500 HP. $500 \text{ HP} = 500 \times 745.7 \text{ W} = 372850 \text{ W}$
     • That's approximately 372.85 kW.

5. Jet Engines:

   • A commercial jet engine might have a power output of around 100,000 HP. $100,000 \text{ HP} = 100,000 \times 745.7 \text{ W} = 74570000 \text{ W}$
     • That’s 74.57 MW (megawatts).

Summary

Using the conversion factor of 1 HP = 745.7 W, you can easily convert horsepower to watts and get a better sense of the power being described in various contexts, ranging from small engines to massive jet engines.
