For finding out Button Size
in mm and inch, we need measure the dia of button with measurement tape. To
find out Button Size in ligne, we need divide button's mm dia by 0.635.
Button size calculation:
1 inches = 40 ligne = 2.54
cm,
1 ligne = 0.635 mm
1 ligne = 0.635 mm
Now find out ligne of a button with 10mm Dia?
Answer: 10 ÷ 0.635 = 15.75 ligne or 16 L (L refers to ligne or ligner)
(Formula: button dia in mm ÷ 0.635= button ligne)
To calculate button measurement
follow below formula to get the button liner;
Button liner = Button diameter
(mm) x 1/0.635
Find the below example with
details;
Suppose, button dia is 15 MM
then what will be the button liner?
Solution:
Button liner = Button Dia /
0.635
= 15MM / 0.635
= 24 L
For 15 mm dia button, we found
button size 24L. Using above formula, we can calculate any button measurement
for garments item.
Button quantity calculation:
1
inches = 40 ligne = 2.54 cm
1
ligne = 0.635 mm
12 pcs = 1 dozen,
12 dozen = 1 gross,
12 gross = 1 GG
1 GG = 1728 pcs (GG means Great Gross)
12 dozen = 1 gross,
12 gross = 1 GG
1 GG = 1728 pcs (GG means Great Gross)
Suppose:
A shirt has 6 buttons, total order quantity 3456 pcs, find out total button quantity for the order.
A shirt has 6 buttons, total order quantity 3456 pcs, find out total button quantity for the order.
Answer: 6
× 3456 ÷ 1728 = 12 GG.
(Formula: number of buttons per
product × order quantity ÷ 1728)
(1 GG = 1728 pcs)
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.
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.
