A micrometer is equivalent to __ of a meter.

A micrometer is equivalent to __ of a meter.

• A. 1/100
• B. 1/1,000
• C. 1/100,000
• D. 1/1,000,000

Answer: (D)

A micrometer is one of the smallest standard metric units, representing one millionth of a meter. The prefix micro- means 10^-6, so a micrometer equals 0.000001 meters. To put it in context: centimeter is 1/100 of a meter (0.01 m), millimeter is 1/1000 of a meter (0.001 m), and micrometer is 1/1,000,000 of a meter (0.000001 m). Therefore, a meter contains 1,000,000 micrometers. The correct choice corresponds to 0.000001 meters. The other fractions refer to larger units: 1/100 is a centimeter, 1/1,000 is a millimeter, and 1/100,000 is 0.00001 meters (10 micrometers).
