What is the difference between bar and psi?

1 bar = 100,000 Pa ≈ 14.5038 psi. Bar is metric (used in Europe), psi is US customary (used for tires, hydraulics).

How many pascals are in one atmosphere?

1 standard atmosphere (atm) equals exactly 101,325 Pa by definition (about 1.01325 bar or 14.696 psi).

They are nearly identical: 1 torr = 1/760 atm ≈ 133.3224 Pa, while 1 mmHg = 133.3224 Pa. The values differ by less than 1 part in 10⁷.

Multiply psi by 6.894757 to get kPa. For example, 30 psi ≈ 206.84 kPa (typical car tire pressure).
