The SI unit kilogram is used to measure which quantity?

Explanation:
The kilogram is the unit used to measure mass, the amount of matter in an object. Mass stays the same whether you’re on Earth or elsewhere (gravity changing weight, not mass). Other quantities use different SI units—for example, time in seconds, length in meters, and electric current in amperes. The kilogram is defined to keep mass measurements precise, and 1 kilogram equals 1000 grams.
