To do the calculations yourself you’ll need three numbers to figure this out: the length of the strand, the size of the beads, and the metric conversion. The metric conversion is 25.4mm to one inch. So to figure out how many beads, first multiply the length of the strand by 25.4. Then divide that number by the size of the beads, and you have the approximate number of beads. For example, the formula for a 16-inch strand of 4mm beads would look like this: 16in x 25.4 = 406.4mm. 406.4mm / 4mm = 101.6 beads.
