How To Convert Pressure Units Calculator
Pressure is force per unit area, and it is written in pascals, bar, PSI or millimetres of mercury depending on the field. A converter routes every value through the pascal so the factors stay exact.

The formula this calculator uses
Result = value x from-factor / to-factor
- value
- Amount you start with
- from
- Size of the source unit in pascals
- to
- Size of the target unit in pascals
How to check the result by hand
- 1
Enter the amount
Type the pressure value you want to convert.
- 2
Pick the source unit
Choose the unit the value is currently in, such as bar.
- 3
Pick the target unit
Choose the unit you want, such as PSI.
- 4
Multiply by the source factor
The value is expressed in pascals using the source unit's size.
- 5
Divide by the target factor
Converting from the base pascal into the target unit gives the answer.
