The SI unit metre is used to measure which quantity?

• A. Distance
• B. Time
• C. Temperature
• D. Mass

Answer: (A)

The metre is a measure of length, so it is used to describe how long or tall something is, i.e., the distance between two points along a straight line. That’s why you’d use metres to state how long a desk is or how tall a person stands. Time, temperature, and mass use completely different units—seconds for time, kelvin or Celsius for temperature, and kilograms for mass—so they aren’t measured in metres. For example, a pencil might be about 0.2 metres long.
