Pressure units are famously inconsistent across countries and industries. If you’re translating gauge readings or comparing datasheets, use one trusted pass through the math instead of multiple rough conversions.
The pascal is one newton per square meter; the atmosphere approximates mean sea-level air pressure; bar is 100 kPa by definition. Tire PSI persists in North America even where metric dominates elsewhere.
P_target = P_source × (Pa per source unit) / (Pa per target unit)
All engineering pressures normalize to pascals the way masses normalize to kilograms. Gauge vs absolute adds offsets in application, not in pure unit algebra—the tool converts unit scales.

Standard atmospheric pressure is defined as 101,325 Pascals or 14.696 PSI.
They are very close. 1 Bar = 0.9869 atm.
This converter translates numeric pressure units. Gauge vs absolute is a physical modeling choice—subtract or add local atmospheric pressure in your engineering step after converting units.
