What is an acre-foot (US survey)?

An acre-foot (US survey) is a volume unit representing the amount of water covering one acre of area to a depth of one US survey foot, equal to 43,560 cubic US survey feet or about 1,233.5 cubic metres.

What does Earth's volume represent in this conversion?

Earth's volume is the total three-dimensional space enclosed by the planet's surface, approximately 1.08321×10^12 cubic kilometres, used here to compare very large-scale volumes with typical water volumes.

Why are the converted values so small?

Because the Earth's total volume is astronomically large compared to typical water volumes measured in acre-feet, resulting in very tiny numerical values after conversion.
