1 bar in standard atmospheres
0.986923 atm

How it is calculated

Formula: atm = bar × 0.9869232667

  1. 1 standard atmosphere = 1.01325 bar
  2. 1 ÷ 1.01325 = 0.98692327 atm

What this means

  • That is 0.9869 standard atmospheres (1 atm = 101.325 kPa = 14.696 psi = 1.01325 bar).
  • The same pressure in pounds per square inch: 14.5038 psi.
  • Quick estimate: 1 × 0.99 ≈ 0.99 atm (exact: 0.986923 atm).
