How to Convert Centipascal to Bar
1 cPa = 1e-07 bar
Example: convert 15 cPa to bar:
15 cPa = 15 × 1e-07 bar = 1.5e-06 bar

Centipascal
The centipascal (cPa) is a unit of pressure equal to one hundredth of a pascal, where 1 pascal (Pa) is the SI unit of pressure defined as one newton per square meter.
History/Origin
The centipascal was introduced as a smaller unit of pressure for more precise measurements, particularly in scientific and engineering contexts, although it is not widely used in practice. It derives from the pascal, the SI base unit established in 1960.
Current Use
The centipascal is rarely used in modern applications; pressure measurements typically utilize pascals or larger units such as kilopascals. It may appear in specialized scientific literature or calibration contexts where fine pressure distinctions are necessary.
Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
