Modern ounce weight and volume measurements, however, come from Britain. A fluid ounce is 1/16th of a pint. A dry ounce weighs 1/16 of a pound or 28.346 grams.

What Is A Gram?

The gram was introduced in France following the French Revolution. The word gramme was adopted by the French in a 1795 decree revising the metric system and defining the gram as the weight of one cubic centimeter of water.
