About Micrograms
A microgram (µg or mcg) is one millionth of a gram (10⁻⁶ g). It is the standard dosing unit for potent medications and micronutrients: vitamin B12 recommended daily intake is 2.4 µg, folic acid supplements are 400 µg, and levothyroxine (thyroid medication) doses are typically 25-200 µg. Air quality standards measure fine particulate matter (PM2.5) in micrograms per cubic meter - the WHO guideline is 15 µg/m³ annual mean. A grain of sand weighs about 50-100 micrograms, and a single snowflake approximately 3 micrograms.
About Ounces
The avoirdupois ounce (oz) is 1/16 of a pound, equal to approximately 28.35 grams. It is the everyday ounce used in the United States and United Kingdom for food portions, household quantities, and general trade. US food packages, recipe measurements, and nutrition labels reference ounces; a standard stick of butter is 4 oz, a can of soup typically 10.75 oz, and a baseball weighs 5-5.25 oz. Unlike the troy ounce (31.10 g) used for precious metals, the avoirdupois ounce (28.35 g) is lighter.
