What is the UK teaspoon based on?

The UK teaspoon is traditionally defined as 1/6 of an imperial fluid ounce, approximately 4.736 mL, but many modern uses apply the metric teaspoon of 5 mL.

What does an acre-foot (US survey) represent?

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

Why are teaspoon to acre-foot conversions resulting in very small numbers?

Because an acre-foot is a very large volume unit, converting small volumes like teaspoons produces very tiny decimal values.
