Bead Weight Calculator
Once you know what one bead weighs the rest is multiplication: 8 mm glass rounds run about 0.6 g, so 100 of them is 60 g. A single bead reads as 0.0 g on a kitchen scale, so weigh twenty and divide by twenty — that is the accurate way to get the per-bead figure. The second line shows how many beads a 100 g bag holds.

Formula
Total bead weight = Beads × Weight per bead
Beads are usually sold by weight rather than by count, so converting a bag weight back into beads is the only way to know whether it covers the pattern. The same 8 mm bead can differ threefold between glass, acrylic and metal, so re-weigh whenever the material changes. Bag weights also include the dust and chips that come with them.

Frequently asked questions
Q. How is Bead Weight Calculator calculated?
Total bead weight = Beads × Weight per bead — Once you know what one bead weighs the rest is multiplication: 8 mm glass rounds run about 0.6 g, so 100 of them is 60 g. A single bead reads as 0.0 g on a kitchen scale, so weigh twenty and divide by twenty — that is the accurate way to get the per-bead figure. The second line shows how many beads a 100 g bag holds.
Q. Can you walk through an example?
With Beads 100, Weight per bead 0.6g, the answer is Total bead weight 60g.
Q. What do I need to enter?
Enter Beads, Weight per bead. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Beads moves the answer to Beads 50 → Total bead weight (g) 30 and Beads 200 → Total bead weight (g) 120. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
Beads are usually sold by weight rather than by count, so converting a bag weight back into beads is the only way to know whether it covers the pattern. The same 8 mm bead can differ threefold between glass, acrylic and metal, so re-weigh whenever the material changes. Bag weights also include the dust and chips that come with them.
