Answer 1

A needle size No.16 is equivalent to 100 mm

Needles have a number and letter classification that describe the size and purpose of the needle.
• The numbers represent the size with the higher number representing the thicker needle (the convention for sizing is that the length and thickness of a needle increases as the size number decreases).
• The letter designates the type and purpose of the needle.
For a sewing needle, you got:
American sizing -European sizing (mm)
8-60 9-65 10-70 11-75 12-80 14-90 16-100 18-110
Formula = (60+add 5 for each number over 8-american size)

Answer 2

What TYPE of sewing needle are you talking about? See below:
The REGULAR SHARP POINT NEEDLE is ideal for all woven fabrics because it helps to produce an even stitch and causes a minimum of fabric puckering. This needle is not recommended for knits, as it has a tendency to "cut" yarns and cause skipped stitches. This needle comes in a wide range of sizes from the finest size 9 to a heavy size 18.

presserfoot100 (3K) The BALL POINT NEEDLE is specifically designed for knit and elastic fabrics and has a "rounded" point rather than a sharp point. This needle pushes between the fabric yarns rather than "cutting through" the yarns. This needle comes in sizes 9 to 16 and the larger the needle size, the more "rounded" the needle point is.

The WEDGE POINT NEEDLE, which is designed for leather and vinyl, easily pierces these fabrics to make a hole that will close back upon itself. This eliminates unattractive holes in the garment, and also reduces the risk of the stitches tearing the fabric. The wedge point needle comes in sizes 11 to 18. The size 11 needle is designed for soft pliable leathers,while size 18 is designed for heavy or multiple layers of leather or vinyl.
