Understand that the SI (International System of Units) defines base units for fundamental physical quantities such as length, mass, time, etc.
Recall that the base unit for mass in the SI system is not the gram (g), but the kilogram (kg), which is the standard unit used worldwide.
Note that the gram (g) is a derived unit equal to one-thousandth of a kilogram (1 g = 0.001 kg), so it is not the base unit.
Recognize that the newton (N) is a derived unit of force, and the liter (L) is a unit of volume, neither of which are base units for mass.
Therefore, the correct SI base unit for mass is the kilogram (kg).
