Kilopascal (Kpa) to Psi (pound per square inch) Pressure conversion formula, chart

1 kPa = 0.1450377377 psi

1 psi = 6.8947572932 kPa

What is a Kilopascal (kPa)?

A kilopascal (kPa) is a unit of pressure in the International System of Units (SI).

• 1 kPa = 1,000 pascal (Pa)

• 1 Pa is the pressure when a force of 1 newton is applied perpendicular to an area of 1 square meter.

Origin:

The pascal is named after Blaise Pascal, a French mathematician and physicist. The kilopascal was adopted in 1971 as a convenient metric unit for measuring pressure.

Usage:

Kilopascals are widely used in engineering, science, and geophysics. Some countries still use imperial or US customary units, but kPa is the standard metric unit worldwide.

What is Psi?

Psi (pound-force per square inch) is a unit of pressure in the imperial and US customary systems.

• 1 psi = Pressure when 1 pound-force acts on 1 square inch

Origin:

Psi comes from the avoirdupois system, which originated in England around 1300 and was used in trade, especially the wool trade.

Usage:

Psi is commonly used for:

• Tire pressure

• Scuba tank pressure

• Gas pipelines

It is widely used in everyday applications in countries like the United States, while pascals are preferred in scientific contexts.
