How to convert kilopascals to millibars
Multiply by 10 — one kilopascal is 10 millibars. That factor is exact: it comes from the definition of the units rather than from a measurement, so it will not change and does not need rounding.
Working 2 × 10 = 20
In words: twenty millibars.
What these units are
The kilopascal and the millibar are covered in the pressure unit guide, along with every other unit on this page.
Questions
How many millibars are in a kilopascal?
One kilopascal is 10 millibars. This figure is exact — it comes from the definition of the unit, not a measurement.
What is 2 kilopascals in millibars?
2 kilopascals is 20 millibars. The working is 2 × 10 = 20.
What pressure should my tyres be?
Look at the sticker in the driver's door frame or the fuel flap, not the number moulded into the tyre — that one is the tyre's maximum, not the manufacturer's recommendation. Most cars sit somewhere around 32 to 35 psi, which is roughly 2.2 to 2.4 bar.
Is my tyre gauge measuring absolute or gauge pressure?
Gauge pressure — the amount above the surrounding air. A tyre reading 32 psi actually contains about 46.7 psi absolute, because atmospheric pressure of roughly 14.7 psi is already pressing on the other side of the gauge. Conversions on this page are between units, and leave that distinction alone.
Why do weather forecasts use hectopascals and millibars interchangeably?
Because they are the same size. One hectopascal is exactly one millibar, so the change from mbar to hPa was a relabelling rather than a conversion. Standard sea-level pressure is 1013.25 of either.
What is the difference between torr and mmHg?
Almost nothing, and the difference is deliberate. A torr is exactly one seven-hundred-and-sixtieth of a standard atmosphere; the conventional mmHg is defined as exactly 133.322387415 pascals. They diverge by about one part in seven million — invisible in medicine, occasionally not in vacuum work.
