Common Pressure Conversions & Formulas
Understanding the relationship between different pressure units is crucial for engineering and scientific tasks. Here are some of the most frequently used conversion formulas:
Pascal (Pa) Conversions
1 kPa = 1,000 Pa
1 MPa = 1,000,000 Pa
1 bar = 100,000 Pa
Imperial & US Units
1 psi (lbf/in²) ≈ 6,894.76 Pa
1 atm = 101,325 Pa
Engineering Units
1 kgf/cm² ≈ 0.98 bar
1 kgf/cm² ≈ 14.22 psi
Frequently Asked Questions (FAQ)
What is the difference between Pa, kPa, and MPa?
The Pascal (Pa) is the base SI unit for pressure. 1 kPa (kilopascal) equals 1,000 Pa, often used in HVAC and tire pressure. 1 MPa (megapascal) equals 1,000,000 Pa, commonly used in hydraulic systems and material strength testing.
How do I convert bar to psi?
To convert bar to psi, multiply the bar value by approximately 14.5038. For example, 2 bar is approximately 29 psi.
Why is absolute pressure different from gauge pressure?
This calculator converts units of pressure (magnitude). However, in practical applications, be aware that “Gauge Pressure” (psig) is measured relative to ambient atmospheric pressure, while “Absolute Pressure” (psia) includes atmospheric pressure (Gauge + Atm).
