About this tool
Convert pressure across SI pascals, atmospheric units, medical millimeters of mercury, and engineering psi.
Formula
value_to = value_from × (factor_from ÷ factor_to), with factors in pascals.
Worked example
1 atm × (101,325 ÷ 6894.7573) ≈ 14.696 psi
Notes
1 bar = 100,000 Pa exactly. 1 standard atmosphere = 101,325 Pa exactly.
