Free Dimensional analysis (factor-label method) web tool

[jack93066]

I often need to do conversions in embedded work, and while it's not especially difficult to do factor-label equations (aka dimensional analysis) by hand, it seemed like an automated tool could be convenient. So I wrote one and put it up on a free web page. Hopefully others will find it useful as well. I welcome any comments or suggestions.

Careful you're not infringing copyright by using the word xfactor as it's a popular tv show in the UK

Any version of Mathcad or Studyworks will do it automatically. Moreover, they allow you to modify the displayed units, and always display the remaining, basic units left over.

For example, if you have something in joules, and you factor out kg, Mathcad automatically displays m^2/s^3 as the remainder.

Your program should already know what the remainder is and tell you, since it's able to tell when the equation is balanced.

as far as I can tell, the link is a very simplistic unit converter.

Great idea, I'll add that. Thanks!
