Definition

Pressure is the effect of a force over an area.

It is the force acting over 1 m2.

Therefore, the definition of pressure is: pressure is the force per unit area.

Equation

Triangle containing different values used in pressure equation.

\(Pressure~p=\frac{\text{Force F}}{\text{Area A}}\)

\(p=\frac{\text{F}}{\text{A}}\)

Where:

  • p = pressure in pascals Pa
  • F = force in N
  • A = area in m2
\(p =\frac{\text{F}}{\text{A}}\)\(p = F \div A\)
\(F = pA\)\(F = p \times A\)
\(A =\frac{\text{F}}{\text{p}}\)\(A = F \div p\)
\(p =\frac{\text{F}}{\text{A}}\)
\(p = F \div A\)
\(F = pA\)
\(F = p \times A\)
\(A =\frac{\text{F}}{\text{p}}\)
\(A = F \div p\)
