Millibars to Kilopascals (mbar to kPa)
Convert millibars to kilopascals: 1 mbar = 0.1 kPa. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.
Formula
1 mbar = 0.1 kPa
kilopascals = millibars × 0.1 — reverse: millibars = kilopascals × 10
The factor is derived from the SI definitions of both units (base unit: Pa) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.
Worked examples
- 5 mbar = 0.5 kPa
- 12.5 mbar = 1.25 kPa
- 100 mbar = 10 kPa

FAQ
How many kilopascals are in one millibar?
1 mbar = 0.1 kPa. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.
What is the formula to convert millibars to kilopascals?
Multiply the value in millibars by 0.1: kilopascals = millibars × 0.1. For example, 5 mbar = 0.5 kPa.
How do I convert kilopascals back to millibars?
Multiply by the inverse factor 10 (millibars = kilopascals × 10), or use the kilopascals-to-millibars page.
