In Canada, we use both SAE and Metric.? I use strictly SAE for machine screws,? nuts and bolts, and hardware for ant stuff etc, etc.? ?I avoid metric like the plague.?
However,? cars are all metric, including cars built in the usa.?
Metric came out in Canada, after I had left school.? ?I still can't relate to it.? ? I have to mentally convert it for everything.? ?80 kmh ?? ?Oh, that's 51 mph, ok, I know how fast I'm going.? ?20C? is? 68F.... ok, now I know how warm / cold it is.? ?Fuel milage is? Liters per 100 km...(62 miles) ..... instead of miles per imperial / US gallon.?
?100 mm? = 10 cm =? aprx 4".? 25.4 mm = 1"? ? 1/4" = 6.35 mm.?
I asked my son one day to get me a short length of? 2x4.? ?(A 2x4? is a piece of wood that is 1.5"? thick x 3.5"? wide).? ?He comes back with a 12" square piece of? 1/2" thick plywood.? WTF ?? "What the hell are u doing"? ? He sez......' How many CM is that ? '? ?F#@K, I don't know Josh.? ? I wasn't abt to convert 1.5"? to cm....and ditto with 3.5"? to? cm.??
