Fun Fact:
There are actually two types of ounces: avoirdupois (28.35g) for everyday items and troy (31.1g) for precious metals! A fluid ounce measures volume, not weight. The phrase 'worth its weight in gold' makes more sense when you know gold is measured in troy ounces!

The original kilogram prototype in France was so precisely made that it only varied by 50 micrograms over 100 years!
