    But how many beads will I need?

    Well, even without a Intel Inside Pentium Processor, you can calculate the number of beads needed for a strand using the following formula:

    Just remember that 1 inch = 2.4 cm = 24 mm (1cm =10mm, right?). So, multiply the lengh of the necklace by 240, and divide by the size of the beads in milimeters. Voila'! You have the number of beads!

    Examples:

    1) 18" necklace made with 4mm beads:
    Number of beads = 18 X 24 / 4 = 108

    2) 32" necklace made with 6mm beads:
    Number of beads = 24 x 24 /6 = 128

    Remeber: since beads may be irregular, this number is approximate. Also, if you are knotting between the beads, add 1 or 2mm for each knot, depending on the tickness. Too complicated? Just buy more beads! ;-)

    In case you don't remember...
    Kilo = 1000 grams = 2.2 pounds
    1/2 kilo = 500 grams = 1.1 pounds
    Gram = .035 ounces
    Ounce = 28.35 grams
    Gross = 12 dozen = 144
    1/2 gross = 72
    Mass = 100 dozen = 1,200
    1 inch = 2.4 cm
    1 cm = 10mm
    1m = 100cm
