How to use this converter
Enter the source measurement in the first field. CalUnit applies the displayed formula and updates the destination value immediately. You can use decimals and negative values, copy the result into your work, and compare it with the reference table. Keep the original unit beside the starting measurement so another reader can verify the calculation. For a different unit pair, open the complete pressure conversion guide or the multi-unit pressure converter.
When this conversion is useful
Read the specified pressure type and operating condition before adjustment. Tire pressure recommendations are generally measured cold and as gauge pressure.
Accuracy and rounding
Use a calibrated pressure gauge for safety-critical work. Converted digits do not increase the precision of the original reading.
Standards references
CalUnit checks physical unit relationships against authoritative measurement references. See the NIST Guide to the SI conversion factors and the BIPM SI Brochure. Regional cooking measures and digital storage conventions are identified separately because their names can represent more than one definition.
