1/16 inch to decimal and mm
1/16" = 0.0625" = 1.587 mm
A sixteenth is the smallest mark on most tape measures, so it comes up whenever you need to be exact on a cut or a gap. It's also a common drill bit and wall-thickness size.
To get the decimal, divide the top number by the bottom: 1 ÷ 16 = 0.0625. For millimeters, multiply that by 25.4, which gives 1.587 mm (about 1.6 mm if you're working with a metric ruler).
