psi to kPa in Engineering
Pressure conversions are essential across all engineering disciplines — from structural loads (PSI, ksi) to fluid systems (feet of water, mmHg) to atmospheric science (atm, mbar). Accurate pressure conversion is critical for piping design, HVAC, and geotechnical analysis.
Pound per Square Inch: Primary US customary pressure unit. Used extensively in mechanical, civil, and petroleum engineering in the United States.
Kilopascal: Common metric pressure unit. 1 kPa = 1000 Pa. Widely used in geotechnical engineering and international building codes.
