Convert Centigrams to Ounces
1 centigram is 0.0003527 oz. One centigram is exactly 0.000352739619496 ounces.
One centigram is 3.5274 × 10^-4 ounces. To convert centigrams to ounces, multiply by 3.5274 × 10^-4; to go the other way, divide by 3.5274 × 10^-4 or multiply by 2834.9523. 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.

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 an ounce?
One sixteenth of a pound. Not to be confused with the fluid ounce, which measures volume.
How many ounces are in a centigram?
One centigram is 3.5274 × 10^-4 ounces. Going the other way, one ounce is 2834.9523 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.
