Question

Which of the physical unit change as we move from MKS to CGS system of measurements?

• A. Length only.
• B. Mass only.
• C. Both length and mass.
• D. Length, mass and time.

Answer 1

The correct option is C Both length and mass.

The units in MKS system are:
Length = metre (m),
Weight = kilogram (kg),
Time = second (s)

The units in CGS system are:
Length = centimetre (cm),
Weight = gram (g),
Time = second (s)
It is observed that as we move from MKS to CGS system, length and weight units have changed while the unit of time remains constant.
