Pressure conversion factor from psi to ksi

Analyzing psi and ksi Units

In this article, we'll explore pressure units and calculate the conversion factor from psi to ksi.

• psi stands for pound-force per square inch, and is a common US unit for pressure. It's often informally referred to as pounds per square inch, although not entirely accurate.
• ksi stands for kilopound-force per square inch, and is equivalent to a thousand psi. It's often informally referred to as kilopounds per square inch, although not entirely accurate.

ksi is simply derived from psi by using the metric prefix k (kilo), which means a thousand (1000). Then, we don't even need to analyze the physical quantity of pressure to find the conversion factor.

How to Convert Pressure psi to ksi

Starting with the definition of ksi:

ksi = 1000 psi

Now, we can divide both sides of the equation by 1000 psi:

ksi / (1000 psi) = 1

This manipulation provides us with the left side of the equation as a convenient conversion factor.

factor = ksi / (1000 psi)
       = 0.001 ksi / psi

Applying this conversion factor to a pressure in psi, psi units cancel out, and we're left with the unit we're aiming for: ksi.

Convert 6000 psi to ksi

Here's an example of how to convert a pressure of 6000 psi into ksi:

6000 psi · factor
= 6000 psi · 0.001 ksi / psi
= 6000 · 0.001 ksi
= 6 ksi

psi to ksi Conversion Factor

Here're the resulting key takeaways.

1 ksi = 1000 psi

Converting a psi unit into ksi is as simple as multiplying it by a conversion factor:

ksi = psi · factor

where factor is exactly:

factor = 0.001
