I simply cannot do metric carpentry or cabinet making. Every adult is two meters tall.
Centimeters my friend, centimeters ...
Carpentry in Germany is done using centimeters and millimeters.
Millimeters is usually enough resolution for anything that one builds by hand.
2 m ~= 6 1/2 feet
2 m = 200 cm = 2000 mm
So, using millimeters, you get about a 2000 resolution for 6 1/2 feet.
That should be plenty for any cabinet.
