How to Convert PSI to Pascal
Conversion Formula
To convert from PSI to Pascal, use the following formula:
Pascal (Pa) = PSI × 6,894.75728
Example Calculation
To convert 15 PSI to Pascal:
15 PSI = 15 × 6,894.75728 = 103,421.3592 Pascal
About PSI (Pounds per Square Inch)
PSI (pound per square inch) is a unit of pressure commonly used in the United States and other countries that use the imperial measurement system. It represents the pressure resulting from a force of one pound-force applied to an area of one square inch.
About Pascal (Pa)
The pascal (Pa) is the SI unit of pressure, defined as one newton per square meter (N/m²). It is named after the French mathematician, physicist, and philosopher Blaise Pascal. The pascal is a relatively small unit, so kilopascal (kPa) and megapascal (MPa) are often used for practical applications.
Reverse Conversion: Pascal to PSI
To convert from Pascal to PSI, use the following formula:
PSI = Pascal × 0.00014503773800722
Example: 10,000 Pa = 10,000 × 0.00014503773800722 = 1.45 PSI
Common Applications
PSI is commonly used for:
- Tire pressure measurement
- Water and gas pipeline pressure
- Industrial equipment specifications
- HVAC systems
Pascal is commonly used for:
- Scientific calculations
- International engineering standards
- Meteorological measurements (often in hectopascals, hPa)
- Acoustic measurements
Conversion Accuracy
The conversion factor used (1 PSI = 6,894.75728 Pa) is based on the standard definition of these units. For most practical applications, rounding to 6,895 Pa per PSI provides sufficient accuracy.
