🔍 Key Concepts

• Horsepower (hp) as a unit of power and how it relates to watts (W) • The approximate conversion factor between mechanical horsepower and watts • Remembering that 1 kilowatt (kW) = 1000 watts and comparing the choices to that

💭 Think About

• Is one horsepower more or less than half of a kilowatt (500 W)? More or less than a full kilowatt (1000 W)? • Think about typical small marine engines rated in horsepower—would each horsepower be as large as 1000 watts, or somewhat less? • Which choice looks like the commonly used engineering approximation for 1 hp when converting to electrical or mechanical power ratings?

✅ Before You Answer

• Recall or look up the standard engineering conversion between hp and W (mechanical horsepower, not metric horsepower). • Compare each answer choice to 1 kW (1000 W) and decide which is a realistic fraction for 1 hp. • Make sure you’re not confusing metric horsepower (~735.5 W) with the more common mechanical horsepower used in many US references.
