How many PSI are in 1 Bar?

1 Bar equals approximately 14.50377 PSI (pounds per square inch). For example, 2.2 Bar = 2.2 × 14.50377 = 31.91 PSI.

What is 1 standard Atmosphere (atm) in Kilopascals (kPa)?

1 standard atmosphere (atm) is defined as exactly 101.325 kPa (or 101,325 Pascals), corresponding to nominal sea-level atmospheric pressure.

How do you convert mmHg to PSI?

1 mmHg (millimeter of mercury) equals approximately 0.0193368 PSI. 1 PSI equals 51.7149 mmHg.

What is the SI unit of pressure?

The International System of Units (SI) standard unit for pressure is the Pascal (Pa), defined as one Newton of force applied per square meter (1 N/m²).

Converters

Pressure Converter

Convert pressure units accurately between Pascals, Kilopascals, Bar, Atmospheres, PSI, and mmHg.

Quick Answer & Summary

A pressure converter recalculates force applied per unit area across Pascals (Pa), Kilopascals (kPa), Bar, PSI, Atmospheres (atm), and mmHg. 1 Bar = 100,000 Pa = 14.5038 PSI. Standard atmospheric pressure at sea level is 1 atm = 101.325 kPa = 14.696 PSI.

Standard Pressure Equivalencies

1 atm = 101325 Pa = 101.325 kPa = 1.01325 bar = 14.6959 psi = 760 mmHg | 1 bar = 100 kPa = 14.5038 psi

Anchored to the SI base unit of pressure: the Pascal (Pa = 1 N/m²).
