How to convert pounds per square inch to atmospheres
To convert a measurement in pounds per square inch to atmospheres, multiply the value by 0.06804596391. The conversion factor comes from the relationship between both units and the pascal.
For example, to convert 5 psi to atmospheres: 5 × 0.06804596391 = 0.340229819549 atm.
What is a pound per square inch?
Pounds per square inch (psi) is an imperial unit of pressure equal to the force of one pound-force applied to an area of one square inch, or about 6,894.76 pascals. Rooted in the imperial system, psi remains the dominant pressure unit in the United States. It appears on tire gauges, air compressors, and hydraulic equipment throughout North America.
Common uses of pounds per square inch include: Tire pressure in the United States; Air compressors and pneumatic tools; Hydraulic system ratings; Plumbing and water pressure specifications.
What is a atmosphere?
A standard atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals, approximating average sea-level air pressure. Defined by the International Union of Pure and Applied Chemistry as a reference pressure, the atmosphere is widely used in chemistry and physics to describe conditions relative to sea level.
Common uses of atmospheres include: Chemistry reference conditions (STP); Diving and hyperbaric medicine; Physics gas-law calculations; Describing high-pressure environments.
