Interesting fact: No two snowflakes form under exactly the same path through temperature and humidity, which is why their shapes vary so much.
The answer: A typical snowflake often weighs around 1 to 3 milligrams, although the exact number varies widely with size, branching, and moisture. Some tiny crystals weigh less than 1 milligram, while clumped flakes can be much heavier.
Snowflakes are delicate and short-lived, which makes direct weighing difficult. Researchers usually estimate mass from size, crystal structure, and density rather than placing a single flake on a scale. Knowing how much snowflakes weigh helps weather radar interpretation, snowfall accumulation models, avalanche studies, and aviation icing forecasts.
