How to convert pressure
Enter a pressure and choose the source and target units. The converter supports pascals, bar, atmospheres, PSI, torr, and kilopascals.
Pressure uses pascals as the base unit: result = amount x source pascal factor / target pascal factor.

Formula model
Base-unit conversion
Atmosphere, bar, PSI, and torr constants use standard engineering definitions.
base = amount * factor + offset
result = (base - targetOffset) / targetFactor
result = (base - targetOffset) / targetFactor
