What does the abbreviation fpm stand for?

• A. Feet Per Minute
• B. Feet Per Meter
• C. Furlongs Per Minute
• D. Foot Per Mile

Answer: (A)

This tests understanding of unit abbreviations for a rate: distance per unit time. fpm stands for feet per minute, meaning how many feet move in one minute. The distance unit is feet, and the time unit is minutes, so it’s a measure of speed or velocity in feet each minute. For example, an airflow speed of 500 fpm means the air travels 500 feet every minute. The other options don’t fit because they use different distance units or mix distance with time in nonstandard ways: feet per meter would be a conversion between units rather than a typical rate in engineering contexts; furlongs per minute uses a far larger unit of distance and isn’t the conventional meaning of fpm; foot per mile would be distance per distance, not a rate over time.
