I prefer binary its easier to count to one than it is to count to 10

I've started switching some of my projects over, for example the bracket I made to mount the battery isolator in my truck I measured in metric and used metric bolts since I figured everything else in the truck is metric anyway.
This didn't cost me any extra since I don't have a lot of metal working tools I was buying the tap and bolts and stuff anyway, those that have non metric stuff already would have to re-buy a lot of tools but me buying for the first time it didn't cost me any extra.
I have learned that when you do work with metal in the metric system you have to overbuild a little more. Metric bolts have a different thread pattern than SAE and it makes them weaker so you have to go up a size. Seems like one of those instances where they decied to make it different just to be different even though its not as good.
