Before using metric units, please perform an acronymectomy procedure.

It's URgent! So who has time to explain acronyms/abbreviations? (Though doing so would help people to respond more quickly....)

Hi there, your calculation results (Wierd) seems to be stemming from improper unit conversions and or improper dimentioning of the units. I recommend that you use MathCad. Basically the formulae are same there cant be a different formula for a different unit system (FPS, CGS, or MKS). Take care that you may be using a force unit as pressure. When using MathCad please use force units as Eg. kgf for kilogram force else you will have Wierd results. Hope that helps.
