About the PSI to Atmosphere conversion
The conversion factor from PSI (psi) to Atmosphere (atm) is 0.068046, meaning 1 psi = 0.068046 atm and inversely 1 atm = 14.69595 psi. That makes the Atmosphere the larger of the two units in the pressure category, where the SI base unit is the pascal. Every ratio here is derived from the SI/international definition rather than a rounded approximation, so results are stable across repeated conversions.
