Quick Reference Values
1 psi = 0.068046 atm. 5 psi = 0.34023 atm. 10 psi = 0.68046 atm. 25 psi = 1.701149 atm. 50 psi = 3.402298 atm. 100 psi = 6.804596 atm.
What is Pounds per Square Inch?
Pounds per Square Inch (psi) is a unit of pressure. Pounds per square inch (psi) measures pressure as force in pounds applied over one square inch of area. It is defined as 1 psi = 6,894.76 pascals in the SI unit system [nist-si-guide]. Psi originated in English-speaking countries for engineering and industrial applications during the 19th century, formalized through American standards for pressure measurement [nist-si-guide]. Psi remains common in the United States, Canada, and the UK for tire pressure, hydraulic systems, and HVAC industries. It is also referenced in international engineering standards [nist-sp-811].
What is Atmospheres?
Atmospheres (atm) is a unit of pressure. One atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals (Pa). It approximates the average air pressure at sea level on Earth. The atmosphere unit is used for expressing pressures in meteorology and engineering [iso-80000]. The atmosphere was originally defined in the 19th century based on average sea-level air pressure. It was standardized by the International Union of Pure and Applied Chemistry (IUPAC) and other bodies to equal 101,325 Pa in the mid-20th century [nist-sp-811]. Atmospheres are used worldwide in scientific fields, including chemistry and physics, and in engineering applications like pressure vessel design. It is less common in everyday use outside these fields [nist-sp-811].
Common Misspellings
