How many 8mm beads in 16 inches?

Answer 1

There are exactly 25.4 mm for each inch. Therefore, there are 16*25.4=406.4 mm in 16 inches. Assuming that 8mm beads occupy exactly 8mm, this would allow 406.4/8=50.8 beads to occupy that length. In other words, you would have 50 beads but only 8/10=4/5 of a bead until you got to the 16 inch mark. Thus the answer is 50 whole beads with a little bit left over given the assumption about bead length.

If the beads are actually a little shorter or they don't have to be aligned along the length exactly, you might be able to get 51 beads "along" the length.
