kPa to mbar – convert kilopascal to millibar
Convert kilopascals to millibars (kPa to mbar) for weather charts, aviation, HVAC and engineering. This page opens the main pressure converter with kPa → mbar pre-selected.
Quick reference: kPa to mbar
1 kPa = 10 mbar. To go from kPa to mbar, multiply by 10.
| Kilopascals (kPa) | Millibars (mbar) |
|---|---|
| 95 kPa | 950 mbar |
| 98 kPa | 980 mbar |
| 100 kPa | 1,000 mbar |
| 101.3 kPa | 1,013 mbar |
| 105 kPa | 1,050 mbar |
What are kPa and mbar?
kPa (kilopascal) is an SI-based pressure unit widely used in engineering, building services and industrial specifications.
mbar (millibar) is traditionally used in meteorology and aviation for atmospheric pressure. It is numerically the same as the hectopascal (hPa).
Why convert kPa to mbar?
- Comparing engineering data in kPa with weather charts in mbar/hPa.
- Translating aviation pressure settings into SI-based values.
- Bringing kPa readings into meteorology-focused software or documents.
- Standardising units across mixed technical and weather data.
kPa to mbar FAQ
- Is 1 kPa exactly 10 mbar?
- Yes. 1 kPa = 1,000 Pa and 1 mbar = 100 Pa, so 1 kPa = 10 mbar exactly.
- What is “standard” pressure in kPa and mbar?
- Standard sea-level pressure is about 101.3 kPa, which is around 1,013 mbar.
- What is the difference between mbar and hPa?
- They are numerically identical. Many modern weather services use hPa, but older equipment and charts often say mbar.
