23300 to meters (23.3) - so i really dont know, think that maybe metric can spare me a bit of headahe (?)
Since 23300cm is 233m, not 23.3m, yes. Using meters will save you a bit of headache, if you do that kind of conversion in your head. Fewer conversions means fewer occasions to get it wrong. By only ever using straight SI units (no multiples, and in particular no "weird units" like feet and pounds), you somewhat reduce the likelihood of pulling a Mars Climate Orbiter.
The nice thing about SI is that things make sense, and things are intrinsically "graspable". Interestingly, both the meter and the kilogram were born out of political intrigues rather than science and in quite dubious times and circumstances. And still, something very sane and practical came out of it.
The accounts of Delambre and Méchain, who by the way did their trip 70 years before... (who are Maxwell and Thomson?), well, the guys who did the trips to Barcelona and Dünkirchen through civil wars, the Spanish-French war, partisans and rebels, and arrests for espionage with strange instruments... are well-documented, and a quite fun story, much like a Three-Musketeer tale.
It's amusing in particular because Méchain was well-known for being the most accurate, pedantic, anal-fixated living person of his time, but after having nearly completed his work, he realized that he did the calculations for the base point wrong by a few hundred meters (well, not meters at that time). So he didn't dare returning home for nearly two years out of shame. Though the difference was well outside the technical capabilities of that time anyway, nobody would have been able to tell if the prototype meter had been 0.01mm too big, nor would they have been able to manufacture it that precisely.
On the other hand, as long as you are firmly confident with the units that you are handling, it doesn't matter even if you use kellicams. Usually, not you will be doing the conversions, but the computer. So as long as the conversion is correct once, there's no headache.
