About this calculator
Pressure is the amount of force applied perpendicular to a surface per unit area: P = F / A. With force in newtons and area in square metres, pressure is measured in pascals (Pa), where one pascal equals one newton per square metre.
Because pressure depends inversely on area, the same force concentrated on a smaller area produces much higher pressure — which is why a sharp knife cuts more easily than a blunt one. This calculator also converts the result into kilopascals, pounds per square inch (psi) and bar for engineering and everyday use.
Frequently asked questions
Pressure equals force divided by area: P = F / A. Newtons over square metres gives pascals.
Divide the pressure in pascals by 6894.757. For example, 6894.757 Pa equals exactly 1 psi.
For a fixed force, pressure is inversely proportional to area, so concentrating the force over a smaller area raises the pressure substantially.
