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.
