Pressure Calculator

Science & Engineering

P=F/S and liquid P=ρgh

Quick Answer

Pressure Calculator: P=F/S and liquid P=ρgh. Pressure Calculator uses standard science & engineering formulas to compute accurate results instantly.

N
Pressure
15.000 kPa
≈ 0.15 atm

Calculation steps

  1. 1Area: 400 cm² = 4.0000e-2 m²
  2. 2P = F/S = 600 ÷ 4.0000e-2
  3. 3P = 15000.0 Pa = 15.000 kPa

Reference pressures

Thumbtack tip≈ 10⁸ Pa
Person standing≈ 1.5×10⁴ Pa
Tank tracks≈ 4×10⁴ Pa
1 atm1.013×10⁵ Pa
10 m underwater (gauge)≈ 10⁵ Pa
Mariana Trench≈ 1.1×10⁸ Pa
Pressure depends on area, not just force — tanks spread weight over wide tracks, needles concentrate it on a tiny point. Liquid pressure grows linearly with depth and acts in ALL directions (same depth = same pressure); dams are built thicker at the bottom for this reason.
