How the conversion works
The input is converted to cubic metres using a defined unit relationship, then converted from cubic metres to the selected output unit. The engine keeps high decimal precision; concise exact results are shown in full, while longer results are rounded for display and marked as approximate.
Supported units and gallon definitions
Metric and cubic units use exact SI relationships. US liquid gallons and imperial gallons are listed separately because they are different sizes. Cooking cups are intentionally excluded from this first version because cup definitions vary by country and context.
