Pressure conversion methodology
1 bar = 100,000 Pa
1 standard atmosphere = 101,325 Pa
760 Torr = 1 standard atmosphere
The calculator uses the pascal as the canonical base unit.
Pressure conversion example

1 atm × 101,325 Pa/atm
Result: 101,325 Pa
Notes
- This calculator converts pressure magnitudes. It does not infer whether a measurement represents gauge pressure, absolute pressure, or another measurement context.
- Mercury-column units (mmHg) are intentionally omitted to avoid ambiguity.
- The calculator uses documented conversion constants without rounding intermediate calculation values. Display formatting may shorten the visible result.
- Negative pressure values are rejected as invalid.
