Why does the UK cup measurement vary?

The UK cup is not an official Imperial or SI unit, and its value can vary depending on the recipe or source. It is commonly considered equivalent to a metric cup of 250 millilitres, but older or informal uses may differ.

What is an acre-foot (US survey)?

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, often used in water resource management.

Is converting from cup (UK) to acre-foot (US survey) commonly needed?

Such conversion is useful primarily to relate small culinary volumes to large water management volumes, enabling cross-scale volume comparisons, though not typical for everyday use.

Tips & Best Practices

Remember that the UK cup is not standardized and may slightly vary by source.
Use this conversion mainly for contextual volume understanding rather than precise engineering calculations.
Be aware that acre-foot (US survey) is mainly applicable to large volume contexts like water resource planning.

Limitations

The UK cup lacks an exact standard definition, which can introduce minor inconsistencies.
Converting from small culinary volumes to large units like acre-foot yields very small numbers that may be impractical in routine scenarios.
Volume values in acre-feet may differ slightly due to variations in the foot definition between US survey and international standards.
