mbar to Pa – convert millibar to pascals
Convert mbar to Pa (millibar to pascals) to move easily between traditional weather and engineering pressure units and pure SI pascals. This page opens the main pressure converter with mbar → Pa pre-selected.

Use main converter (mbar → Pa) or switch to Pa → mbarThe homepage also converts Pa, kPa, bar, mbar, atm and psi.
Quick reference: mbar to Pa
One millibar is defined as exactly 100 Pa, so: Pa = mbar × 100. Examples:
| Pressure (mbar) | Pressure (Pa) |
|---|---|
| 1 mbar | 100 Pa |
| 10 mbar | 1,000 Pa |
| 50 mbar | 5,000 Pa |
| 100 mbar | 10,000 Pa |
| 500 mbar | 50,000 Pa |
| 1013 mbar | 101,300 Pa |
Why convert millibar to pascals?
mbar to Pa is useful when you:
- Translate weather pressure charts into pure SI units.
- Compare HVAC or clean room specifications that use mbar and Pa.
- Convert barometer readings from older millibar scales.
- Prepare physics or engineering reports in standard pascals.

Because 1 bar = 100,000 Pa, the millibar is a neat decimal stepping stone: 1 mbar = 100 Pa = 0.1 kPa.
