mbar to kPa – convert millibar to kilopascal
Convert millibar to kilopascal (mbar to kPa) for weather charts, aviation, meteorology and engineering. This page links to the main pressure converter with mbar → kPa pre-selected.
Quick reference: mbar to kPa
One millibar is the same as one hectopascal: 1 mbar = 1 hPa = 0.1 kPa. So you divide mbar by 10 to get kPa.
| Millibar (mbar) | Kilopascal (kPa) |
|---|---|
| 950 mbar | 95 kPa |
| 980 mbar | 98 kPa |
| 1,000 mbar | 100 kPa |
| 1,020 mbar | 102 kPa |
| 1,050 mbar | 105 kPa |
What are mbar and kPa used for?
Millibar (mbar) is traditionally used in meteorology to describe atmospheric pressure. Weather maps and forecasts often use mbar or the very similar hectopascal (hPa).
Kilopascal (kPa) is an SI unit commonly used in engineering, building physics and some aviation and industrial contexts.
Why convert mbar to kPa?
- Comparing weather pressures with engineering specifications given in kPa.
- Bringing data from aviation or meteorology into SI-based calculations.
- Standardising pressure units in a technical report or model.
- Working across international sources that use different conventions.
mbar to kPa FAQ
- Is 1 mbar exactly 0.1 kPa?
- Yes. 1 mbar = 100 Pa, and 1 kPa = 1,000 Pa, so 1 mbar = 0.1 kPa exactly.
- What is normal sea-level pressure in kPa?
- Standard sea-level pressure is about 1013 mbar, which is about 101.3 kPa.
- What is the difference between mbar and hPa?
- Numerically they are the same. 1 mbar = 1 hPa. Many modern weather services now use hPa, but older charts and instruments still say mbar.
