What percentage of a cloud is actually made of water?

Less than 0.0001 percent

Background

A cloud looks soft and full, but it is almost only air. Only a tiny fraction, less than one ten-thousandth, is really water. Still, a big cloud can hold tons of tiny droplets. When it rains out, you can feel how much was inside after all.
