Pressure under a person weighing 70 kgf on 0.05 m² of shoe

Answer: pressure = 13,729.3 Pa (in bar 0.1373 bar, in psi 1.991 psi).

What we know

  • Force: 70 kgf = 686.4655 N (converted to the unit the formula takes)
  • Contact area: 0.05 m²

Step by step

Given
F = 686.4655 N, A = 0.05 m²
Formula
P = F / A
Substitute
P = 686.4655 / 0.05
Result
P = 13,729.3 Pa

The physics

Pressure is force concentrated on an area. The same 700 N (a standing adult) is harmless through shoe soles but devastating through a stiletto heel — one hundredth the area means one hundred times the pressure.
