About these measurements

Pressure is force per unit of area.

The base reference used here is the pascal. One torr is 133.3223684 base units; one pound-force per square inch is 6,894.757293 base units.

Important distinctions

Gauge and absolute pressures must not be mixed. This converts units without changing the reference pressure.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
