QUESTIONS & ANSWERS
Ask a Question-
Does this show bead circumference in mm. Also does it convert a bead/beads to carat weight at all? Would be good to know, thanks.
It just measures in mm. It does not convert to carat weight but simple scales that weigh down to 0.01g or down to 0.001g are really inexpensive these days.
