Bar to PSI Conversion Explanation
This conversion factor is derived by expressing both the bar and the psi (pounds per square inch) in their equivalent values of the base unit, the pascal (Pa). The ratio of their defined pascal values yields the direct conversion factor.
Definition
A bar is a metric unit of pressure defined as exactly 100,000 pascals (Pa). A psi (pound per square inch) is an imperial unit of pressure defined as approximately 6,894.76 pascals (Pa).
Principle
To convert between any two units, both are expressed in a common base unit. The conversion factor is the ratio of their base unit equivalents. Here, dividing the pascal value of a bar by the pascal value of a psi gives the factor for bar to psi.
Assumptions
- The definition of 1 bar as exactly 100,000 Pa is used.
- The definition of 1 psi as exactly 6,894.76 Pa is used.
Cautions
- The provided derivation uses the standard definitions, but the numerical precision of the psi-to-pascal factor (6,894.76) may vary slightly depending on the source or standard.
- The conversion factor is exact based on the given definitions, but any practical calculation should consider the required precision of the result.
