What is Pressure Calculator?
Pressure (P) is defined as the force applied perpendicular to the surface of an object per unit area over which that force is distributed. In the simplest terms, it is how concentrated a force is.
The standard unit of pressure is the Pascal (Pa), which is equivalent to one Newton per square meter (N/m²).
How to Use
The relationship between these three variables is linear and easy to remember using the formula P = F / A.

Atmospheric Pressure
Even though you can't feel it, the air above you has weight. At sea level, the atmosphere pushes down with a pressure of about 101,325 Pascals (or 14.7 pounds per square inch).

Frequently Asked Questions
Common questions about this calculator
What is a Kilopascal (kPa)?
1 kPa is 1,000 Pascals. Since a single Pascal is very small pressure (about the weight of a sheet of paper on a table), kPa is more commonly used in engineering.
Are pressure and force the same?
No. Force is the total 'push', while pressure is how 'sharp' or concentrated that push is. 100N of force on a pinhead is extreme pressure; 100N on a mattress is barely noticeable.
How does depth affect pressure?
In fluids (like water), pressure increases with depth because the weight of the fluid above you is pushing down. For every 10 meters you go underwater, pressure increases by about 1 atmosphere.
What is Absolute vs Gauge pressure?
Gauge pressure is measured relative to atmospheric pressure (showing 0 at sea level). Absolute pressure includes the atmospheric pressure.
