Pressure Calculator
A 500 N force on a 10 cm × 10 cm square exerts 50000 Pa, from P = F/A.
50000 Pa
- In kPa
- 50 kPa
- In MPa
- 0.05 MPa
- In bar
- 0.5 bar
- In atm
- 0.4934616334 atm
- In psi
- 7.251886887 psi
Step-by-step solution
- P = F ÷ A
- P = 500 ÷ 0.01
- P = 50000 Pa
Pressure Formula
P = F / A
P pressure (Pa = N/m²), F force normal to the surface, A area
Worked Example
A 500 N force spread over 0.01 m² (10 cm × 10 cm):
- P = F ÷ A
- P = 500 ÷ 0.01
- P = 50000 Pa
In MPa: 0.05 MPa · In bar: 0.5 bar · In atm: 0.4934616334 atm · In psi: 7.251886887 psi
Pressure units
1 bar = 100 kPa, 1 atm = 101.325 kPa, 1 psi = 6.895 kPa. The pressure converter covers every unit, including inches of water and mmHg.

Density Calculator
ρ = m / V
ρ density, m mass, V volume; specific gravity = ρ / ρ(water)
Example: A 2.7 kg block with a volume of 1 litre (0.001 m³): Density ρ = 2700 kg/m³.

Buoyancy Calculator
F_b = ρ V g
ρ density of the fluid (not the object), V displaced volume, g gravitational acceleration
Example: A 2 litre object fully submerged in fresh water: Buoyant force F_b = 19.6133 N.
Frequently asked questions
Why do sharp knives cut better?
The same force on a smaller area gives a higher pressure. Halving the edge width doubles the pressure.
How do I get the force on a piston?
Choose “force” and enter the pressure and the piston area (π r²): 6 bar on a 50 mm bore cylinder gives about 1178 N.
