Question

The si unit of pressure is called derived unit why

Answer 1

Answer:

there are 7 fundamental units - kg,m,sec,amphere , candela,Kelvin,mole

all other units are called derived units because those units are derived from the basic fundamental units .

for pressure -

pressure = force/area

force = mass * acceleration

N= kgm/s^2

area= m^2

Pascal= N/m^2

Pascal = kgm/s^2 m^2

Pascal = kg/ms^2

so it's derived from basic units hence it's called derived units

                                                     OR

The units of pressure is called derived units because it is simply derived from base unit which is distance and a derived unit which is force, which is derived from acceleration, a derived unit as well, and mass, a base unit. As we all know, work is defined as the force x distance. Thus making work a derived unit.
