Accuracy and rounding
Useful for tires, pumps, HVAC, weather, and technical specs. Check whether your source uses gauge or absolute pressure.
Pressure factors are fixed, but real-world readings may be gauge pressure or absolute pressure depending on the instrument.
For tires and pumps, match the gauge precision. For engineering specs, keep enough decimals to avoid tolerance drift.
How to convert mmHg to psi
