Question

1. To convert from meters to millimeters, divide by 1,000.

True

False

2. To convert from foot-pounds per second to horsepower, multiply by 550.

True

False

Answer 1

#1 is false. The correct operation is multiplication.

#2 is true. I think "550 ft-lbs/sec" was the original definition of 1 HP .

Answer 2

1. False.

A millimeter is 1/1000th of a meter, so 1 meter * 1000 ≠ 1 millimeter.

2. True.

Every horsepower is 550 foot-pounds, so 1 foot-pound * 550 equals 1 horsepower.
