While a common scientific estimate puts a standard water drop at approximately 0.05 mL, the actual volume of a single waterdrop is not a fixed unit. The answer to how much water per waterdrop is influenced by surface tension, the dropper's size, and even temperature, making every droplet a unique result of physics in action.

Water's surface tension is approximately 72.8 millinewtons per meter at 20°C, a high value that directly explains the science behind waterdrops. This remarkable property, driven by hydrogen bonds, is at the core of how water behaves in droplets and on various surfaces.
