speed units VS "measure tool" units

Yes, but then again, that's only convenient if you stick to the 360 degree for a circle unit of measurement. Any serious discipline like calculus and such use radians instead of degrees to measure circles.... but I see your point that you can't convert some units unless you convert ALL the units (something which is unlikely)...

We still carry the burden of old civilizations that DID NOT use 10 as their "base" number, such as the romans and their love for the number twelve (hence you ask for a dozen eggs or say that noon occurs at 12:00) and other funkier base numbers like the SEXagesimal system (I admit I DO LOVE the name ) which has 60 as it's base number (minutes and seconds, for example), and so on and so forth....

Let's hope that one day the whole world agrees to unify and we do away with silly things like remembering the length of a dead guy's foot or another dead guy's thumb .
