About Pressure Converter
What Is a Pressure Converter?
A pressure converter transforms pressure measurements between different units. Pressure is force per unit area and is measured in many different units across industries. Automotive and industrial applications use PSI, weather uses millibars or hectopascals, science uses Pascals, medicine uses mmHg, and diving uses atmospheres. This converter bridges all these systems for quick and accurate conversion.
Common Pressure Conversions
Key factors: 1 atm = 101,325 Pa = 101.325 kPa = 1.01325 bar = 14.696 PSI = 760 mmHg = 760 Torr. 1 bar = 100,000 Pa = 14.5038 PSI. 1 PSI = 6,894.76 Pa. Standard atmospheric pressure at sea level is defined as 1 atm.
How to Use This Converter
Enter a pressure value, select the source and target units, and click Convert. The full conversion table shows your value in all pressure units simultaneously.
Frequently Asked Questions
What is PSI?
PSI stands for pounds per square inch. It is commonly used in the US for tire pressure, water pressure, and industrial applications. Standard tire pressure is typically 30-35 PSI.
What is the difference between bar and atm?
They are very close: 1 atm = 1.01325 bar. The bar is slightly smaller. In many practical applications they are nearly interchangeable.
Why is blood pressure measured in mmHg?
Historically, blood pressure was measured using mercury manometers. The unit mmHg (millimeters of mercury) persists in medical practice even though modern devices are digital.
