What does the stitch number mean on a sewing machine?

On most modern sewing machines, the stitch length control indicates the length of a single stitch is in millimetres. So a length of 3.0 means each stitch is 3mm long (or just under 1/8″). Therefore, the bigger the number, the smaller the stitch (and the more stitches that can fit in an inch of sewing).
