3/4 inch to decimal and mm
3/4" = 0.75" = 19.050 mm
3/4 is the nominal thickness of most plywood and the size of standard garden hose and many pipe fittings.
To get the decimal, divide the top number by the bottom: 3 ÷ 4 = 0.75. For millimeters, multiply that by 25.4, which gives 19.050 mm (about 19.0 mm if you're working with a metric ruler).
