Convert kilopascal to psi

What is a kilopascal?

Pressure is on the basic physical characteristics of the world around us and it can be measured in different units. Talking about the systematic options, they are represented by pascal.

This unit was named after a well-known French scientist and corresponds to the pressure that the force of one newton creates on a surface of ​​one square meter. Thus, according to its definition, one pascal or Pa for short is equal to 1 N/m2.

Furthermore, a kilopascal is a derivative of this option. Prefix kilo always refers to 1000 or 103. Thus, a kpa is the same as 1000 Pa or 103 Pa. Such a derivative is useful for different scientific purposes and mathematical and physical calculations. While working with large numbers, it is more convenient to utilize kpa than Pa.

As for the correspondence to other units, one kilopascal is equal to 0.01 bar or 0,145 psi.

What is a psi?

English-speaking countries such as Canada, Great Britain and the US prefer to stick to their own units that differ from the systematic options. For instance, for pressure, a psi option exists that has its own meaning and value.

Pound-force per square inch is what stays behind this unusual abbreviation. That is why, it is the same as the pressure of a corresponding force that influences an area of one square inch. If we wish to convert this option into Pa, it will give us approximately 6895.

In practice, some derived psi options are also common in the USA. Thus, ksi corresponds to a thousand psi. Another option is Mpsi, which is equal to one million psi. These units are more often utilized for scientific purposes due to their quite large values. They can be more convenient in the calculations of the properties of metals and related tasks.
