PSI to Pascals Converter
Convert pounds per square inch to pascals — one psi is 6,894.76 Pa. Results update as you type; exact factors shown.
One pound per square inch is 6,894.7573 pascals — see the exact factor, not a rounded rule of thumb.
How the psi to pascals converter works
Pressures convert through the pascal (1 N/m²). One bar is exactly 100 kPa; a standard atmosphere is exactly 101.325 kPa; 1 psi is 6.894757 kPa (a pound-force on a square inch); 1 mmHg is 133.322 Pa by the conventional definition.
The UK is metric for most trade and science but keeps miles, pints, stone and mpg (with the imperial gallon) in daily life.
