Kilopascals to Bar (kPa to bar)

Convert kilopascals to bar: 1 kPa = 0.01 bar. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.

Formula

1 kPa = 0.01 bar

bar = kilopascals × 0.01 — reverse: kilopascals = bar × 100

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 kPa = 0.05 bar
12.5 kPa = 0.125 bar
100 kPa = 1 bar

FAQ

How many bar are in one kilopascal?

1 kPa = 0.01 bar. 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 kilopascals to bar?

Multiply the value in kilopascals by 0.01: bar = kilopascals × 0.01. For example, 5 kPa = 0.05 bar.

How do I convert bar back to kilopascals?

Multiply by the inverse factor 100 (kilopascals = bar × 100), or use the bar-to-kilopascals page.
