Key Facts

Formula	Pressure = Force ÷ Area
Triangle	P = F/A, F = P×A, A = F/P
Units	N/m² (also called Pascals, Pa) or N/cm²
Key Fact	1 Pa = 1 N/m²
Remember	Same force, smaller area = MORE pressure

Pressure Applications

Pressure = Force ÷ Area. Sharp knives, stiletto heels, snowshoes - all examples of changing area to change pressure!

Pressure Formula

Pressure = Force ÷ Area. Units: N/m² or Pascals (Pa). Same force over smaller area = MORE pressure!
