Which of the following is the SI base unit for mass?
A
gram
B
ounce
C
kilogram
D
pound
Verified step by step guidance1
Understand that the International System of Units (SI) defines base units for fundamental physical quantities, including mass.
Recall that the SI base unit for mass is the kilogram, which is the standard unit used worldwide in scientific measurements.
Recognize that the gram is a derived unit equal to one-thousandth of a kilogram, so it is not the base unit.
Note that ounce and pound are units of mass used primarily in the imperial system, not the SI system.
Conclude that among the options given, the kilogram is the correct SI base unit for mass.
