An essential pressure conversion reference guide for industrial piping, valves, and high-pressure fitting applications. Easily convert values between Bar, PSI, Megapascals (MPa), and Kilograms per Square Centimeter (kg/cm²).
Standard Conversion Formulas
Use these constant values to compute pressure across different industrial metrics:
- 1 Bar = 14.5038 PSI = 0.1 MPa = 1.0197 kg/cm²
- 1 PSI = 0.0689 Bar = 0.00689 MPa = 0.0703 kg/cm²
- 1 MPa = 10 Bar = 145.038 PSI = 10.197 kg/cm²
- 1 kg/cm² = 0.9806 Bar = 14.2233 PSI = 0.09806 MPa
