KilopascalkPa
Target UnitThe kilopascal (kPa) is a unit of pressure in the International System of Units (SI), defined as 1,000 pascals. The pascal is the SI derived unit for pressure, defined as one newton per square meter. Therefore, a kilopascal quantifies the force of one newton distributed over an area of one square meter, multiplied by 1,000. It is commonly used to measure pressures in various fields, such as meteorology, engineering, and manufacturing, and provides a clear standard that facilitates comparisons across different systems.
Current Use
The kilopascal is extensively used today across multiple industries, including meteorology for measuring atmospheric pressure, engineering for evaluating material strength, and in automotive industries for tire pressure specifications. It is also prevalent in hydraulics and the food and beverage industry for measuring pressure in processing equipment. The kilopascal is often used in technical specifications and guidelines, ensuring accuracy and uniformity in pressure measurement.
Fun Fact
The kilopascal is commonly used in weather reports to describe atmospheric pressure, making it a household term.
Convert PSI to Kilopascal (psi to kPa)
Convert PSI (lb/in²) to Kilopascals (kPa). Whether you are calibrating machinery imported from Europe or simply reading a dual-unit gauge, converting PSI to the SI standard unit kPa ensures compatibility with modern scientific and engineering standards.
Multiply PSI by roughly 6.89. For example, 30 psi × 6.89476 = 206.8 kPa.

Kilopascal
pressure • SI Unit
Definition
The kilopascal (kPa) is a unit of pressure in the International System of Units (SI), defined as 1,000 pascals. The pascal is the SI derived unit for pressure, defined as one newton per square meter. Therefore, a kilopascal quantifies the force of one newton distributed over an area of one square meter, multiplied by 1,000. It is commonly used to measure pressures in various fields, such as meteorology, engineering, and manufacturing, and provides a clear standard that facilitates comparisons across different systems.
History & Origin
The kilopascal was introduced as a part of the metric system, which originated in France during the late 18th century. The pascal itself was named after Blaise Pascal, a French mathematician, physicist, and inventor, who made significant contributions to fluid mechanics and the study of pressure. The use of kilopascals became more prevalent in the 20th century as the metric system was adopted globally for scientific and engineering purposes.
Etymology: The term 'pascal' is derived from Blaise Pascal's name, recognizing his pioneering work in the field of pressure and fluid dynamics. The prefix 'kilo-' comes from the Greek word 'chilioi', meaning 'thousand', which indicates that a kilopascal is one thousand pascals.
Current Use
The kilopascal is extensively used today across multiple industries, including meteorology for measuring atmospheric pressure, engineering for evaluating material strength, and in automotive industries for tire pressure specifications. It is also prevalent in hydraulics and the food and beverage industry for measuring pressure in processing equipment. The kilopascal is often used in technical specifications and guidelines, ensuring accuracy and uniformity in pressure measurement.
💡 Fun Facts
- •The kilopascal is commonly used in weather reports to describe atmospheric pressure, making it a household term.
- •One kilopascal is roughly equivalent to 0.145 pounds per square inch (psi), a unit often used in the United States.
- •The kilopascal is also utilized in the food industry for high-pressure processing, a method to extend shelf life without preservatives.
