Convert Centigrams to Troy ounces

1 centigram is 0.0003215 ozt. One centigram is exactly 0.000321507465686 troy ounces.

One centigram is 3.2151 × 10^-4 troy ounces. To convert centigrams to troy ounces, multiply by 3.2151 × 10^-4; to go the other way, divide by 3.2151 × 10^-4 or multiply by 3110.3477. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 44. A hundredth of a gram, or ten milligrams.

Factors are entered by hand from NIST Handbook 44 rather than derived from a units library, so the ones that terminate are exact rather than rounded.

How do you convert centigrams to troy ounces? The converter and the working

  1. 1.Take the measurement in centigrams.
  2. 2.Multiply by 3.2151 × 10^-4 — that is how many troy ounces fit in one centigram.
  3. 3.To go back the other way, divide by 3.2151 × 10^-4, or multiply by 3110.3477.

Worked example: 25 centigrams to troy ounces

Formula
cg × 3.2151 × 10^-4 = ozt
Arithmetic
25 × 3.2151 × 10^-4 = 0.01 ozt
Answer
25 cg = 0.01 ozt

The factor is rounded for display; the figure above is computed from the full value.

What is a centigram?

A hundredth of a gram, or ten milligrams. It survives mainly in pharmacology and in school exercises about metric prefixes.

What is a troy ounce?

Exactly 31.1034768 grams, and the only ounce bullion is ever quoted in. It is about 10% heavier than the ounce on a kitchen scale, so a "pound" of gold — twelve troy ounces — is lighter than a pound of anything else.

How many troy ounces are in a centigram?

One centigram is 3.2151 × 10^-4 troy ounces. Going the other way, one troy ounce is 3110.3477 centigrams. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
