About Pound/sq inch

Pounds per square inch (psi) is an imperial unit of pressure widely used in the US for tire pressure, hydraulics, and engineering.

Common uses: tire pressure (US), hydraulics, HVAC.

About Newton/sq cm

The newton/sq cm (N/cm²) is a unit of pressure and stress. One newton/sq cm equals 10000 pascals. UnitConvertLab converts it against every other pressure unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: pressure calculations, engineering and science, education.
