Pounds per Square Inch to Kilopascals Converter

To convert a measurement in pounds per square inch to kilopascals, multiply the value by 6.894757. The conversion factor comes from the relationship between both units and the pascal.

For example, to convert 5 psi to kilopascals: 5 × 6.894757 = 34.473786 kPa.

Pounds per square inch (psi) is an imperial unit of pressure equal to the force of one pound-force applied to an area of one square inch, or about 6,894.76 pascals. Rooted in the imperial system, psi remains the dominant pressure unit in the United States. It appears on tire gauges, air compressors, and hydraulic equipment throughout North America.

Common uses of pounds per square inch include: Tire pressure in the United States; Air compressors and pneumatic tools; Hydraulic system ratings; Plumbing and water pressure specifications.

A kilopascal equals 1,000 pascals and is the most common metric unit for everyday pressures such as tire inflation. The kilopascal became widespread as metric countries standardized on SI units, replacing older units like the kilogram-force per square centimeter in engineering and automotive specifications.

Common uses of kilopascals include: Tire pressure in metric countries; Blood pressure in some clinical contexts; HVAC and building pressure specifications; Compressed air and pneumatic systems.

Here are some common values converted:

1 psi = 6.894757 kPa 5 psi = 34.473786 kPa 10 psi = 68.947573 kPa 50 psi = 344.737865 kPa 100 psi = 689.475729 kPa
