Standard atmosphere (atm) equals 101325 Pa. Originally defined as 760 mm mercury column at 0°C. Used as reference for physical and chemical properties. Set 100°C as water boiling point at this pressure
PSI (pound per square inch) is a US-based pressure unit. 1 psi equals approximately 6,895 pascals in SI units. PSI absolute indicates pressure relative to vacuum. PSI gauge shows pressure relative to atmospheric pressure
Megapascal (MPa) is a metric unit of pressure equal to 1 million pascals. One MPa equals 10 bar, 145 psi, or 0.1 atmospheres. Used in engineering, physics, and materials science for high-pressure systems. Can measure tensile strength and express Young's and shear moduli
Tool converts pressure values between different units. Users can enter values and select units for conversion. Supports copy-paste and manual input. Includes conversion tables for various applications
PSI measures force per square inch, equivalent to one pound per square inch. Widely used in US and imperial systems. Essential in automotive, plumbing, and engineering applications
kg/cm² measures pressure as force per unit area in kilograms. PSI represents pressure in pounds per square inch for gases and liquids. Converter tool provides instant pressure unit conversions
