What you need to know

  • Pressure is force divided by area, measured in pascals (1 Pa = 1 N/m²).
  • The same force spread over a bigger area gives a smaller pressure.
  • A block resting on a table presses down with its weight, mg, over the area of its base.
  • Convert centimetres to metres before working out the area in m².
