* Ounces (oz) and grams (g) are units of weight (or mass).

* There are 28.35 grams in 1 ounce.

Therefore:

* 1 ounce is greater than 1 gram.

However, if you're comparing a larger number of grams to a smaller number of ounces, the grams could be greater. For example, 50 grams is greater than 2 ounces.
