Average Raindrop

An ordinary water droplet on its final descent/Events & Phenomena

A typical raindrop is about 2 mm in diameter and falls at roughly 9 m/s — fast enough to sting but slow enough that umbrellas work. Raindrops are not teardrop-shaped; small ones are nearly spherical and larger ones flatten into a hamburger-bun shape due to air resistance. A single raindrop contains around 50 million billion water molecules, which sounds impressive until you realize it weighs about as much as a grain of sand.
