How many millgrams of gold does it take to make an ounce?

Answer 1

Short answer: 31,103 milligrams.

There are 31.03 grams in a troy ounce, the measurement standard by which precious metals are weighed (the troy ounce is used for little else today). Since there are 1000 milligrams in a gram, that would mean that there are 31,030 milligrams in a troy ounce.

Note the a troy ounce is about 10% heavier than a the more common avoirdupois ounce. For reference purposes, there would be about 28,350 milligrams in an avoirdupois ounce. Again, keep in mind that gold is weighed in troy ounces. Also remember that there are only 12 ounces in a troy pound.

Answer 2

28349.52 milligrams are in an ounce. It does not matter whether its gold you are weighing or if it is leaves. There will be the same number of milligrams in an ounce no matter what you weigh. The amount of what you are weighing is the only thing that will change. For example, if 1 cat weighed 10lbs. it would still be equal to 1,000,000 snowflakes equalling 10lbs.

-note- Im not saying a cat weighs 10lbs. nor does 1,000,000 snowflakes equal 10lbs.
