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 US uses customary units (US gallon, short ton, °F) in daily life; NIST SP 811 gives the exact SI factors.
