When force is in newtons(N) and area is in m2, then pressure P is in N / m2 or pascal (Pa).
The following numerical example compares the pressure exerted on the floor by a girl of weight 400N, when she wears a pair of shoes with high heels(having small area of contact with floor) and when she wears a pair of slippers with large area of contact with floor.
With high heels
Area of heels=100X10-6m2 (assumed)
=4X106 N/m2 or Pa
Area of slippers=3000X10-6m2
=0.13X106 N/m2 or Pa
Area of slippers is 30 times greater than area of heels. So pressure is 30 times greater in case of heels.
