What is the SI base unit for mass?

Explanation:
In SI, mass is measured using the base unit that specifically quantifies how much matter something contains—the kilogram. This unit is the standard for mass and is defined by fixing the value of Planck’s constant, linking mass to fundamental physics. The other units measure different quantities: the meter for length, the second for time, and the Kelvin for temperature. So the kilogram is the correct base unit for mass because it is the designated standard for that quantity.
