Explanation

Electric power: Rate of energy transfer.

It is measured in watts (W), or one joule per second.

Energy/Work: Measured in joules (J).

Charge: Measured in coulombs (C).

Pressure: Measured in pascals (Pa).

Electric current: Measured in amperes (A).

Electric resistance: Measured in ohms (Ω).

Temperature: Measured in kelvin (K).

Torque: Measured in newton metres (N m).

Velocity: Measured in meters per second (m/s).

Acceleration: Measured in meters per second squared (m/s²).

Explanation

SI (International System of Units) fundamental units include meter (length), kilogram (mass), and second (time).

All other units like Newton, Joule, etc., are derived from these base units.

Explanation

The SI unit of pressure is Pascal (represented as Pa) 

in SI base units, one kilogram per meter per second squared (N/m2 or kg m-1s-2)

Definition of Pressure: Pressure can be defined as the force acting per unit area.

***

The SI unit of energy/work is the joule (J)
