Pressure conversion factor from tsf to ksf

Analyzing tsf and ksf Units

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

tsf is a common US unit of pressure. It stands for tons-force per square foot, although it's often slightly inaccurately referred to as tons per square foot. It's equivalent to two thousand (2,000) pounds-force per square foot (psf).
ksf stands for kilopound-force per square foot, and is a common US unit for pressure that is equivalent to one thousand (1,000) pounds-force per square foot (psf). It's often informally referred to as pounds per square foot, although not entirely accurate.

Both tsf and ksf are is simply derived from psf. Then, we don't even need to analyze the physical quantity of pressure to find the conversion factor.

Starting with the definition of tsf and ksf we can quickly see the relationship between both:

tsf = 2000 psf
ksf = 1000 psf
tsf = 2 ksf
ksf = 0.5 tsf

Now, we can divide both sides of the equation by 0.5 tsf:

ksf / (0.5 tsf) = 1

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

factor = ksf / (0.5 tsf)
       = 2 ksf / tsf

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

Here's an example of how to convert a pressure of 3 tsf into ksf:

3 tsf · factor
= 3 tsf · 2 ksf / tsf
= 3 · 2 ksf
= 6 ksf

Here're the resulting key takeaways.

1 ksf = 0.5 tsf

Converting a tsf unit into ksf is as simple as multiplying it by a conversion factor:

ksf = tsf · factor

where factor is exactly:

factor = 2
