Understand that mass is a measure of the amount of matter in an object.
Recall that the International System of Units (SI) defines specific base units for different physical quantities.
Identify that the SI base unit for mass is the kilogram, symbolized as kg.
Note that the mole is the SI unit for amount of substance, the meter is for length, and the second is for time.
Conclude that among the given options, the kilogram is the correct SI unit used to measure mass.
