How this tool works
Inputs, units and where to find them
| Input | Unit | Typical source |
|---|---|---|
| Pressure or stress value | The number exactly as written on the drawing, data sheet or quote. | |
| Unit of the entered value | choice | The unit printed beside the value; check prefixes such as k, M and m. |
Method and formulas
- Value in Pa = entered value × factor of the entered unit.
- Value in each other unit = SI value ÷ that unit’s factor.
- Factors used (1 unit = … Pa): kPa 1000; MPa (N/mm²) 1000000; GPa 1000000000; bar 100000; mbar 100; psi 6894.7572931684; ksi 6894757.2931684; standard atmosphere 101325; kgf/cm² 98066.5; mmHg 133.322387415; inHg (32 °F) 3386.388640341; inH₂O (4 °C) 249.08891.
- Example: 100 psi = 689,475.73 Pa.
Limitations
- Displayed values are rounded to eight decimal places; small values use significant figures.
- Gauge and absolute pressures differ by atmospheric pressure; this converter does not change the reference.
- Example values are illustrations. Replace them with values for your actual task.
Typical uses
- Convert pressure or stress values on drawings, data sheets and quotes
- Check supplier data given in other units
Who it is for
- Engineers
- Technicians
- Buyers and estimators
What you get
- The pressure or stress in each listed unit
- Value in Pa
Interpreting the result
- Use the unit your specification is written in, and keep the original value on record.
