pascals to torr | Exact Decimal + Formula

1 Pascal = 0.007501 Torr

One torr equals about 133 pascals (exactly 133.322368 Pa). Real-world use: scientific and engineering pressure measurements; everyday values are small, so kpa is common. This page expresses those values in torr, which is used for vacuum systems and blood-pressure history (mmhg). Enter any value above — the result updates instantly, and a 1–1000 reference table follows below.

About Pascal and Torr

Pascal (Pa)

The pascal is the SI unit of pressure — one newton of force per square meter.

Where it's used: Scientific and engineering pressure measurements; everyday values are small, so kPa is common.

Torr (Torr)

A torr is 1/760 of an atmosphere, essentially equal to one millimeter of mercury.

Where it's used: Vacuum systems and blood-pressure history (mmHg).

Pressure represents force acting over a unit of area. Standard pressure scales like PSI, bar, kilopascals (kPa), and atmospheres (atm) are utilized in HVAC, hydraulics, automotive tire inflation, and pneumatic tool operations.

Converting pressure ratings accurately is essential for equipment safety. For instance, European machinery gauges often use bar, whereas American compressors use PSI, necessitating quick conversions to prevent system over-pressurization. Our pressure calculators help technicians easily convert between scales, ensuring pressure vessels, hydraulic lines, and automotive tires are maintained at the correct operational levels.
