Unit of mass is kg and unit of volume is m³. So Unit of Density is kgm^-3.

Unit of distance is m and unit of time is s. So unit of velocity is ms^-1.

Change in velocity has unit ms^-1 and time has unit s. So unit of acceleration is ms^-2.

Unit of mass is kg and unit of acceleration is ms^-2. So Unit of Force in fundamental quantities is kgms^-2.

Unit of force is kgms^-2 and unit of area is m². So unit of pressure is kgm^-1s^-2.
