Have you ever wondered why Jewelry Findings and Beads are measured in Millimeters (mm)?

     Millimeters are a fine precise form of measurement.

     When you are designing it is very important to have precise measurements to make sure
     your pieces fit together correctly.

     Here is a simple conversion chart to help you convert millimeters to inches

·         1mm = just over 1/32 inch

·         2mm = just over 1/16inch

·         3mm = almost 1/8 inch

·         4mm = 5/32 inch

·         5mm = just over 3/16 inch

·         6mm = almost 1/4 inch

·         7mm = almost 9/32 inch

·         8mm = 5/16 inch

·         9mm = almost 3/8 inch

·         10mm = just over 3/8 inch

·         11mm = almost 7/16 inch

·         12mm = almost 15/32 inch

·         13mm = just over 1/2 inch

·         14mm = almost 9/16 inch 

·         15mm = almost 19/32 inch

·         16mm = 5/8 inch

·         17mm = almost 11/16 inch

·         18mm = just over 11/16 inch

·         19mm = 3/4 inch

·         20mm = 25/32 inch

·         21mm = just over 13/16 inch

·         22mm = almost 7/8 inch

·         23mm = 29/32 inch

·         24mm = just over 15/16 inch

·         25mm = almost 1 inch

·         25.4mm = 1 inch

     Millimeter to inches Calculator conversion:

     Divide your millimeter amount by 25.4

     Example: 10mm divided by 25.4 = .3937 inches

     Example: 8mm divided by 25.4 = .3149 inches

     Example of how to figure how many beads you will need to make a  necklace

     To find out how many 6mm beads you will need to make a 16" necklace.

     6mm=.2362 inches so 16 inches divided by .2362 inches per bead = 67.73

     You will need approximately 64 beads. You want to subtract a few beads from the total above for
     your clasp or other type of closure.
