 # Question: What Is Newton’S SI Units?

## Is time a derived unit?

Fundamental units of measurements are kilograms, meters, and seconds—in regards to mass length, and time.

These derived units can be expressed in terms of fundamental units, such as acceleration, area, energy, force, power, velocity and volume.

Derived quantities will be referred to as time, length, and mass..
