Example Calculations
Example 1: Convert 15,000 Pa to PSI
Given: Pressure = 15,000 Pascals
Formula: PSI = Pa ÷ 6894.76
Calculation: PSI = 15,000 ÷ 6894.76 = 2.176
Result: 15,000 Pa ≈ 2.176 PSI
Example 2: Convert 30 PSI to Pascals
Given: Pressure = 30 PSI (typical car tire)
Formula: Pa = PSI × 6894.76
Calculation: Pa = 30 × 6894.76 = 206,842.8
Result: 30 PSI ≈ 206,843 Pa (or 206.8 kPa)

Understanding PSI and Pascals
What is PSI?
PSI (Pounds per Square Inch) is a unit of pressure that measures the force applied over one square inch of area. One PSI is equivalent to one pound-force applied to an area of one square inch. This unit is widely used in the United States and other countries using the imperial system, particularly in automotive, plumbing, and engineering applications.
PSI Applications
- •Tire pressure measurement (cars, bicycles, aircraft)
- •Water and gas line pressure
- •Hydraulic and pneumatic systems
- •Industrial compressors and tools
What is a Pascal?
The Pascal (Pa) is the SI unit of pressure, named after French mathematician Blaise Pascal. One Pascal equals one Newton per square meter (N/m²). It's the standard unit in scientific work and is used internationally. Because the Pascal is relatively small, kilopascals (kPa) and megapascals (MPa) are commonly used for practical applications.
Pascal Applications
- •Scientific research and calculations
- •Weather forecasting and meteorology
- •Engineering stress analysis
- •International standards and specifications
Conversion Factor Explained
The conversion factor between PSI and Pascals is 6,894.76. This means:
- →1 PSI = 6,894.76 Pascals (multiply PSI by 6894.76 to get Pa)
- →1 Pascal = 0.000145038 PSI (divide Pa by 6894.76 to get PSI)
- →Standard atmospheric pressure = 14.696 PSI = 101,325 Pa
Important Notes
- ⚠️Pascals are the standard SI unit, essential for international work
- ⚠️PSI is commonly used in the US and for consumer applications
- ⚠️Be aware of absolute vs. gauge pressure (PSIG vs. PSIA)
- ⚠️Scientific publications typically require SI units (Pascals)
