A megaliter (ML) is a metric unit representing one million litres or 1,000 cubic metres, commonly used to measure large water volumes in hydrology and engineering.

How does the UK gallon differ from the US gallon?

The UK gallon, or imperial gallon, is defined as exactly 4.54609 litres, which is larger than the US gallon and used primarily where imperial units are applied.

Why convert megaliters to UK gallons?

Conversions from megaliters to UK gallons help relate metric water volumes to imperial measurements used in fuel capacities, marine operations, and historical volume records.
