Why the MPa to bar conversion factor is 10
The conversion factor holds because both megapascal (MPa) and bar are units of pressure defined relative to the pascal (Pa), the SI base unit. When expressed in pascals, the numerical relationship between them results in a simple multiplier of 10.
Definition
The megapascal (MPa) is one million pascals, and the bar is defined as 100,000 pascals. Therefore, 1 MPa equals 10 bar.
Principle
To find the conversion factor, express both units in the common base unit of pascals and then determine the ratio. Dividing the MPa value in pascals by the bar value in pascals yields the factor of 10.
Assumptions
- The definitions of megapascal (1,000,000 Pa) and bar (100,000 Pa) are exact as provided.
- The conversion is based solely on these definitions and not on experimental measurements or approximations.
Cautions
- This conversion factor is exact based on the given definitions. However, in practice, the result should be rounded to the precision required for the specific calculation.
- Do not confuse the bar with other units of pressure that are similarly named but have different definitions.
