Conversion Formulas:

• 1 Pa = 0.00001 bar = 0.000009869 atm = 0.0075 Torr = 0.000145 psi = 0.0075 mmHg
• 1 bar = 100,000 Pa = 0.9869 atm = 750.06 Torr = 14.5038 psi = 750.06 mmHg
• 1 atm = 101,325 Pa = 1.01325 bar = 760 Torr = 14.6959 psi = 760 mmHg
• 1 Torr = 133.322 Pa = 0.001333 bar = 0.001316 atm = 0.019337 psi = 1 mmHg
• 1 psi = 6,894.76 Pa = 0.068948 bar = 0.068046 atm = 51.7149 Torr = 51.7149 mmHg
• 1 mmHg = 133.322 Pa = 0.001333 bar = 0.001316 atm = 0.019337 psi = 1 Torr
