Frequently Asked Questions
What pressure units are supported?
Our pressure converter supports 8 pressure units: Atmospheres (atm), Bars (bar), Kilopascals (kPa), Megapascals (MPa), Millimeters of Mercury (mmHg), Pascals (Pa), Pounds per Square Inch (psi), and Torr (Torr).
What is the difference between psi and bar?
1 bar = 14.5038 psi. Bar is a metric unit of pressure, while psi (pounds per square inch) is an imperial unit commonly used in the United States.
What is standard atmospheric pressure?
Standard atmospheric pressure is 1 atm = 101.325 kPa = 14.6959 psi = 760 mmHg = 1.01325 bar = 101325 Pa.
What is the difference between absolute and gauge pressure?
Absolute pressure is measured relative to a perfect vacuum, while gauge pressure is measured relative to atmospheric pressure. Gauge pressure = Absolute pressure - Atmospheric pressure.
Why is pressure measured in so many different units?
Different pressure units are used in different contexts. For example, psi is common in the US for tire pressure, atm is used in chemistry, bar is used in meteorology, and Pa is the SI unit.
How accurate are these pressure conversions?
Our pressure converter uses precise conversion factors based on the SI unit Pascal (Pa). All conversions are accurate to 6 decimal places.
