A student wants to measure the mass of three different rocks.

Which SI unit should the student use?

millimeters

grams

ampere

kelvin

Answer 1

The student wants to measure the MASS of three rocks. What units would you use?

Millimeters is a unit for length so you wouldn’t use millimeters for mass.

Ampere is the base unit of measure for electrical current so you wouldn’t use that.

Kelvin is a measurement of temperature so you wouldn’t use that.

Thus, the answer is grams. Grams is a unit of measure for mass.

Answer 2

I've never heard of ampere, so it's either grams or ampere.
