Hello, Just fooling around trying to find the average speed of a gas molecule using the kinetic theory of gases equation. I cannot seem to get the following to convert: In[] := Convert [Sqrt[Joule/Gram],Meter/Second] Out[]= PUKE! However, I can get the conversion to go if I convert Joules to its fundamental base units: In[]:= Convert[ PowerExpand[Sqrt[KiloGramMeter/Second^2 Meter/Gram], Meter/Second] // N Out= 31.6 Meter/Second Please tell me that there is an easier way :) Is there a function that will convert units to meter, grams, second,Kelvin? The SI,CGS, MKS functions don't cut it. SI[Joule] = Joule.... Is there an MMA package enhancement floating around? Thanks, Rick Sprague
