(Metal. & Assaying) A weight divisible first into a hundred parts, and then into smaller parts. Note: The metallurgists use a weight divided into a hundred equal parts, each one pound; the whole they call a centner: the pound is divided into thirty-two parts, or half ounces; the half ounce into two quarters; and each of these into two drams. But the assayers use different weights. With them a centner is one dram, to which the other parts are proportioned.
