We usually use the outer diameter of the button to represent the size of the button, so what is the conversion between various size units of the button.
1 L(LIGNES) is equal to 0.635mm, and the conversion relationship is: 1L=0.625MM, 1MM=1/25 inches (INCH).
Buttons can also be divided by size (i.e. diameter size), commonly known as 14 #, 16 #, 18 #, 20 #, 60 #, and so on!
Its labeling formula is: diameter=model * 0.635 (mm).
