Convert Nanograms to Micrograms
Convert Nanograms (ng) to Micrograms (µg) instantly and accurately.
Conversion Formula
µg = ng × 0.001
About Nanograms
A nanogram (ng) is one billionth of a gram (10⁻⁹ g). This is the standard mass unit in analytical chemistry, pharmacology, and toxicology for detecting trace substances. Blood plasma concentrations of hormones, drugs, and environmental contaminants are routinely reported in nanograms per milliliter (ng/mL). A typical therapeutic blood level for many medications is in the range of 10-500 ng/mL. In forensic science, nanogram-level DNA quantities can be amplified by PCR to yield a full genetic profile.
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.
