Having your printer ‘scale to fit’ your Letter or A4 paper shouldn’t matter, but the numbers are 9 pt font size, so too much reduction will make it hard to read, whereas a larger scaled print might be great for your studio/shop wall. I keep it under my keyboard.
Rows contain equivalent measurements; 1/64th = .015625 = 0.4m
Columns are the systems: Fractional English, Decimal English and Metric.
A. Can I drill for a 6mm-fine screw tap with only my English drill set?

B. Need the closest English dado to 18mm plywood
C. How much bigger or smaller are the adjacent 64ths to 3/32 ?
