Ligne is a French word meaning “line” and it is abbreviated with the letter L. Internationally, ligne is used to recognize button size. Ligne is a liner unit (1/40 inch) used to measure the diameter of buttons. Usually, watchmakers, button-makers, and hat-makers use Ligne to measure their product size. Calculation of Button Ligne for Garments is discussed in the following.
Before calculating button line we should know following measurement:
- 1 inches = 40 ligne = 2.54 cm,
- 1 ligne = 0.635 mm
- 12 Pcs = 1 Dozen,
- 12-Dozen = 1 Gross,
- 12 Gross = 1 GG (1728 pcs).
