Pressure Units & Calculator
Pressure = force per area. Conversion does not change a gauge reading into an absolute reading. Water-column values use a conventional factor; actual fluid density varies.
Detailed explanation & worked examples
Conversion method
Base value = input × source factor + source offset. Output = (base value − target offset) ÷ target factor. Only units from this family can be converted together.
Worked example
For the first two units below: 1 Pascal becomes 0.00100000 Kilopascal.
| Unit | Multiplier | Offset |
|---|---|---|
| Pascal | 1 | 0 |
| Kilopascal | 1000 | 0 |
| Megapascal | 1000000 | 0 |
| Bar | 100000 | 0 |
| Standard atmosphere | 101325 | 0 |
| Pounds per square inch | 6894.757293168 | 0 |
| Inches of water (conventional) | 249.08891 | 0 |
