 To find out the button line, we should to know below measurement for easy understand:
  • 1 inches = 40 ligne = 2.54 cm = 25.4 mm
  • 1 Ligne = 0.635 mm 
  • 1 Dozen = 12 pcs
  • 12 Dozens = 1 Gross
  • 12 Gross = 1 GG
  • 1 GG = 1728 pcs
Let's find out the button line/ligne with simple example:

 Formula: Button ligne = Button Dia in mm / 0.635 or Button Dia in mm X 1 / 0.635

 Q.1: Suppose, Button length (dia) is 8 mm, Now figure out the button ligne for 8mm?
Solution:
Button Ligne = Button Dia in mm / 0.635
                      = 8 / 0.635
                      = 12.59 ligne = 12 L                                  [ L = Ligne ]

 Q.2: Find out the button ligne for 12mm button dia?
Solution:
Button Ligne = Button dia in mm X 1 / 0.635
                      = 12 X 1 / 0.635
                      = 18.897 ligne
                      = 18 L                                                   [ L = Ligne ]

 Q.3: Shirt has 6 buttons, order quantity total 4320 pcs. Now find out total button quantity in GG?
Solution:
Button quantity in GG = per shirt button X total quanty / 1728
                                    = 6 X 4320 / 1728                  [ 1 GG = 1728 pcs ]
                                    = 15 GG

 Note: We need to additional quantity (minimum 5%) in case of shortage due to defective or damage in bulk production.
