PSI to kPa: Everything You Need to Know

What is PSI?

Pounds per square inch (psi) is a unit of pressure that measures the force exerted by a fluid per unit area. It is commonly used to measure the pressure of gases and liquids in engineering, construction, and the automotive industry.

What is kPa?

Kilopascals (kPa) is another unit of pressure that measures the force exerted by a fluid per unit area. It is a metric unit, meaning it is part of the International System of Units (SI). kPa is often used to measure the pressure of gases in weather forecasting and other scientific applications.

Converting PSI to kPa

To convert psi to kPa, you can use the following formula:

kPa = psi x 6.89476

For example, 10 psi is equal to 68.9476 kPa.

Converting kPa to PSI

To convert kPa to psi, you can use the following formula:

psi = kPa / 6.89476

For example, 100 kPa is equal to 14.5038 psi.

Applications of PSI and kPa

PSI and kPa are used in a wide variety of applications, including:

• Engineering: PSI is used to measure the pressure of fluids in pipelines, pressure vessels, and other engineering systems. kPa is used to measure the pressure of gases in engines, turbines, and other mechanical systems.
• Construction: PSI is used to measure the pressure of concrete during construction and to test the strength of concrete structures. kPa is used to measure the pressure of air in pneumatic tools and other construction equipment.
• Automotive: PSI is used to measure the pressure of tires, brake fluid, and other fluids in vehicles. kPa is used to measure the pressure of gasoline and diesel fuel in fuel systems.
• Weather Forecasting: kPa is used to measure the pressure of air in the atmosphere. This information is used to create weather forecasts and to track the movement of weather systems.
