What is a megaliter and where is it commonly used?

A megaliter (ML) is a metric volume unit equal to 1,000,000 litres or 1,000 cubic metres, primarily used in hydrology and engineering for expressing large water volumes.

How does an acre-foot (US survey) compare to a megaliter?

An acre-foot (US survey) is the volume that would cover one acre to a depth of one US survey foot, approximately 1,233.5 cubic metres; 1 megaliter equals about 0.8107 acre-foot (US survey).

Why might conversions between these units not be perfectly exact?

Because the acre-foot uses US survey feet, slightly different from international feet, small discrepancies can occur, and conversions are approximate for general use.
