The formula for pressure is: \(\text{pressure} = \frac{\text{force}}{\text{area}}\) The unit of force is a Newton (N). The unit of area is a square metre (m 2). The unit of pressure is a Pascal (Pa).

while density is covered in Units of measure. If the pressure and area are known the formula can be rearranged to calculate force by multiplying both sides by area. A box of books exerts a ...
