Hi all,

I am doing a research project relating to structural integrity and much of the literature I have been going through features units measured in the (I believe exclusive to the US/Canada?) units of KIPS and KSI.

Can anyone offer help on where I can learn to convert these to SI units?

Just about the most useful site on the net for an engineer is this, I recommend you bookmark it!

Seems a KIP is equal 4 448.221 6 newtons
and a KSI is 6 894 757.28 pascals

Or you can think of a KIP as a non SI unit of force equal to 1000 pounds-force - hence the links to US documentation.

KSI is the KIP per square inch - more convenient than pounds per square inch when you are looking at tensile strength of materials.

Almost entirely used in the US - but you'll find them occasionaly in Europe on US based designs. I've come across them in seismic qualification documents for equipment such as generators built to US Mil spec standards - I just pass them on to a tame structural/seismic colleague
