What is Pounds per Square Inch (PSI)

Pounds per square inch (PSI) is a pressure measurement unit in the imperial system. It represents the pressure from one pound of force applied over one square inch of area.

Key Facts About PSI

• Exact value: 1 PSI = 6.89476 kPa
• Relation: 1 PSI ≈ 0.068 atm, 27.7 inHg
• Abbreviation: PSI
• Usage: Widely used in tire pressure, gas cylinders, and industrial systems.

What is Kilopascal (kPa)

The kilopascal (kPa) is a metric unit of pressure equal to 1,000 pascals. One pascal is one newton per square meter. kPa is common in weather reports, fluid mechanics, and engineering design.

Key Facts About kPa:

• Exact value: 1 kPa = 0.145038 PSI
• Relation: 100 kPa = 1 bar = 14.5038 PSI
• Abbreviation: kPa
• Usage: Found in hydraulics, meteorology, and construction.

Step 3: Result = 43.51 PSI

Example 3: 400 kPa to PSI

Step 1: PSI = kPa × 0.145038

Step 2: Substitute = 400 × 0.145038

Step 3: Result = 58.02 PSI

Applications of PSI and kPa Conversions

• Tire pressure: Cars and bikes list PSI or kPa depending on region.
• Aviation: Aircraft systems use PSI, but weather data often uses kPa.
• Engineering: Hydraulic and pneumatic systems require both units.
• Meteorology: Atmospheric pressure is reported in kilopascals.
• Industrial safety: Boilers and compressors need accurate PSI to KPa conversion.
