What is an ounce?
The avoirdupois ounce is one sixteenth of a pound, exactly 28.349523125 grams. Americans use it for food portions, packaged goods and baby weights. It is a weight, not to be confused with the fluid ounce used for volume, or the troy ounce used for gold.
What is a kilogram?
The kilogram is the SI base unit of mass. Since 2019 it has been defined from the Planck constant rather than from a metal cylinder kept near Paris. Most countries use it for body weight, luggage allowances and groceries; one kilogram is about 2.2 pounds.
