Which unit is used to measure mass?

Which unit is used to measure mass?

• A. kg
• B. mm
• C. L
• D. m

Answer: (A)

Mass is how much matter is in an object, and the unit used to measure it in the metric system is the kilogram, written as kg. The kilogram is the standard unit for mass, and we sometimes use grams (g) for smaller amounts since 1 kilogram equals 1000 grams. The other options measure different things: millimeters and meters measure length (how long something is), while liters measure volume (how much space a liquid or solid occupies). So the unit that measures mass among these is the kilogram. For examples, a book might have a mass near 1 kilogram, while a pencil is about 10 grams.
