A 200-hp engine can deliver, in SI units, an average power of 1) 200 W 2) 74600 W 3) \( 149000 \mathrm{Wp}=746 \mathrm{~W}) \) 4) 298000 W 5) 326000 W

A 200-hp engine actually delivers a power output of 149,000 watts (or 149 kW) when converted to SI units. This conversion comes from the amazing fact that one horsepower is equivalent to about 746 watts. So, to find the horsepower in watts, simply multiply the horsepower by 746, which absolutely gives you 149,000 W. Now, to help you avoid a common pitfall—always double-check your conversions! Many might think "200 times something" would yield a much grander, much bigger figure. Remember, while horsepower sounds mighty, the conversion to watts scales it down to something a bit more manageable. Keep track of your units, and you'll definitely steer clear of some engine-rumbling mistakes!
