Pressure conversion factor from ksi to psi

Analyzing ksi and psi Units

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

• 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.
• 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 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 ksi to psi

Starting with the definition of ksi:

ksi = 1000 psi
psi = 1/1000 ksi

Now, we can divide both sides of the equation by 1/1000 ksi:

psi / (1/1000 ksi) = 1

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

factor = psi / (1/1000 ksi)
       = 1000 psi / ksi

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

Convert 25 ksi to psi

Here's an example of how to convert a pressure of 25 ksi into psi:

25 ksi · factor
= 25 ksi · 1000 psi / ksi
= 25 · 1000 psi
= 25000 psi

ksi to psi Conversion Factor

Here're the resulting key takeaways.

1 psi = 1/1000 ksi
      = 0.001 ksi

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

psi = ksi · factor

where factor is exactly:

factor = 1000
