To round to the nearest 1/16 of an inch, multiply your decimal by 16. I prefer to round to the nearest 1/16 of an inch. Step two: Converting your decimal to a useable fraction:.If, however, you want fractions of an inch (1/16, 1/4, 1/2), rather than a decimal, try this: Since you probably need to reserve a bit of space for your bead tips and a clasp, I would round down to 80 beads. 2362 inches (per bead) = 84.67 beads per necklace. From Example 2 above, you know that a 6mm bead =. If you are trying to figure out how many 6mm beads you need for a 20' necklace, you can use this decimal value directly. (or divide your centimeter amount by 2.54)Įxample 1: 2mm divided by 25.4 =.

Step one: Divide your millimeter amount by 25.4.

If you have millimeters (or centimeters), and you want inches:

For amounts over an inch, you want to first convert the fractional part, then add the whole inches part:Įxample: 2-1/4 inch = 1 divided by 4, then plus 2 = 2.25 inchĮxample: 1-5/8 inch = 5 divided by 8, then plus 1 = 1.625 inch.

Step one: Convert any inch fractions to decimals.Įxample: 1/4 inch = 1 divided by 4 = 0.25 inchĮxample: 1/16 inch = 1 divided by 16 = 0.0625 inch.

If you have inches, and want to know how many millimeters:

7mm = almost 9/32 inch (= a bit over 1/4 inch).

4mm = 5/32 inch (= a bit over 1/8 inch).

If you have the millimeters, and need to know the inches: If you have the inches, and need to know the millimeters:

In case you've never gotten along with millimeters, or in case you need to do some conversions and never got along with algebra, this page contains easy conversions back and forth between inches and millimeters. but is 1/8' larger or smaller then 5/32'? Even if you've always hated the metric system, that row of millimeter sizes is clearer than that row of inch fractions: it's obvious that 4mm is larger then 3mm. If those were converted to inches, they would be (in order) approximately 1/8 inch, 5/32 inch, 1/4 inch, 5/16 inch, and 3/8 inch. For example, the gluing surfaces on most of our flat pad posts are 3mm, 4mm, 6mm, 8mm, and 10mm.
