Common mistakes to avoid
- Dividing when you should multiply. Because 1 pound per square inch = 0.068948 bars, the answer should be smaller than the number you started with.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.
How these units are defined
- Pound per square inch (psi): The dominant US pressure unit for tyres and plumbing. The accepted value is a measured or conventional figure rather than an exact definition, so the factor shown is rounded.
- Bar (bar): 100,000 pascals, close to average atmospheric pressure. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
