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.
Well there are 4 6mm beads in an 1", so there would be 64 6mm beads in 16".
For all practical purposes an 8mm drill is equal to 5/16 inch.
8mm = 0.315 inches. The closest English bit is 5/16"
16" x 16" = 256 square inches.
16 inches = 0.4064 meters
16 inches = 40.64 centimeters
16 feet 5 inches is 197 inches.
16 inches = 406.4 millimeters
16 yards=576 inches
16 miles = 1,013,760 inches
It is about 16 inches
16 inches = 40.64 centimeters
