🧪 Pascal Conversion
Express Pascal readings in kPa, MPa, bar, atm, psi, psig, Torr, and mmHg.
Pascal is the SI base unit for pressure, but most specifications use larger units. This converter summarizes them all in one place.

Megapascals (MPa)0.101325
Bar (bar)1.01325
Atmospheres (atm)1
Pounds per square inch (psi)14.69595
Pounds per square inch gauge (psig)-0
Torr (Torr)760
Millimeters of mercury (mmHg)759.99989

Formula
kPa = Pa ÷ 1,000
MPa = Pa ÷ 1,000,000
bar = Pa ÷ 100,000
psi ≈ Pa ÷ 6,894.757
mmHg ≈ Pa ÷ 133.322
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Pascals are universal in theory, but practical documentation often relies on alternative units. This converter ensures you can translate lab or simulation results into the units your partners use.
Including both absolute (psi) and gauge (psig) outputs makes it straightforward to communicate with plant operators or HVAC technicians.
Frequently Asked Questions
What is psig compared to psi?
psig subtracts atmospheric pressure from psi, matching gauge readings.
Can I convert Pa to mmHâ‚‚O?
Not on this page, but apply a factor of 9.80665 Pa per mmHâ‚‚O if needed.
Does temperature affect the conversion?
Unit conversions are fixed; only fluid properties may vary with temperature.
How precise are the values?
Outputs use the precision defined in the shared pressure utilities, offering engineering-grade accuracy.
