Understanding the Conversion Formula
This calculator uses a standard reference system based on Pascal (Pa) as the base unit.
Step 1: Convert Any Unit → Pascal (Pa)
All input values are first converted into Pascals using fixed scientific conversion factors:
- 1 kPa = 1000 Pa
- 1 bar = 100,000 Pa
- 1 atm = 101,325 Pa
- 1 Torr = 133.322 Pa
- 1 PSI = 6,894.76 Pa
So the formula becomes:
Pressure (Pa) = Input Value × Conversion Factor
Step 2: Convert Pascal → Target Unit
After converting to Pascal, the value is converted into the target unit:
Final Value = Pressure (Pa) ÷ Target Unit Factor
Example Conversion
Let’s understand with a real example:
Convert 2 atm into PSI
Step 1: Convert atm to Pascal
1 atm = 101,325 Pa
So:
2 atm = 2 × 101,325 = 202,650 Pa
Step 2: Convert Pascal to PSI
1 PSI = 6,894.76 Pa
So:
202,650 ÷ 6,894.76 = 29.36 PSI (approx.)
Final Answer:
👉 2 atm ≈ 29.36 PSI
This process happens instantly inside the calculator without manual effort.
