Time is the physical quantity that has the same unit in all the three systems of units, i.e., CGS (Centimeter-Gram-Second) system, FPS (Foot-Pound-Second) system, and SI (Systeme International) system.
CGS System:
In the CGS system, the unit of time is second (s).
FPS System:
In the FPS system, the unit of time is second (s).
SI System:
In the SI system, the unit of time is second (s).
Explanation:
Mass and length have different units in different systems of units. For example, the unit of mass in CGS system is gram (g), in FPS system it is pound (lb), and in SI system it is kilogram (kg). Similarly, the unit of length in CGS system is centimeter (cm), in FPS system it is foot (ft), and in SI system it is meter (m). Therefore, time is the only physical quantity that has the same unit in all the three systems of units.
