Question: Figure out ligne no of a button with 10mm Dia? 

Answer: To figure out the ligne number of a button with a diameter of 10mm, you can use the formula:

Ligne= (Diameter in mm/Ligne per mm)

In this case, the ligne per mm is given as 0.635 mm. So, for a button with a diameter of 10 mm:

Ligne= (10 mm/0.635 mm)

≈15.74

So, the ligne number for a button with a diameter of 10 mm is approximately 15.748. Since ligne numbers are typically whole numbers, you might round it to the nearest whole number. In this case, the ligne number would be 16.
