kPa to bar Converter - Kilopascal to Bar
Kilopascal (kPa) to Bar (bar)
Direct answer
1 kPa = 0.01 bar
bar = kPa × 0.01
Converter
Conversion formula
bar = kPa × 0.01
kPa = bar × 100
Example: 10 kPa = 10 × 0.01 = 0.1 bar.

Conversion Factor from Kilopascal to Bar
The conversion factor of 0.01 bar per kilopascal arises because both units are defined in terms of the base pascal (Pa) unit. One kilopascal equals 1,000 pascals, and one bar equals 100,000 pascals. Comparing these definitions gives the direct relationship.
Definition
Kilopascal (kPa) and bar are units of pressure. The kilopascal is a multiple of the SI base unit pascal, where 1 kPa = 1,000 Pa. The bar is a metric unit where 1 bar = 100,000 Pa.
Principle
The conversion is based on expressing both pressure units in the common base unit of pascals. The numerical factor is derived from the ratio of their definitions relative to the pascal.
Assumptions
- The conversion uses the standard definitions: 1 kPa = 1,000 Pa and 1 bar = 100,000 Pa.
Cautions
- The conversion factor is exact based on these definitions, but rounding may be necessary when applying the result to practical calculations.
