The same engine also converts between Pa, bar, psi, atm and mmHg – just pick the units you need from the pressure category on the homepage.

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 mbar95 kPa
980 mbar98 kPa
1,000 mbar100 kPa
1,020 mbar102 kPa
1,050 mbar105 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?

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.
