Imperial quart is typically associated with united Kingdom and Commonwealth countries (historically), while Metric cup is typically associated with australia, New Zealand, United Kingdom, Canada (recipes and cooking measurement).
Formula
metric cups = imperial quarts × 4.54609
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart equals 0.0011365225 base units, and 1 metric cup equals 0.00025 base units, so dividing one by the other gives the direct imperial quart-to-metric cup factor of 4.54609.

Historical origin. Imperial quart was not the invention of a single named person; it developed through the process described above.
Understanding the Metric cup
Metric cup (metric cup) measures volume. The metric cup used in Australia, New Zealand, the UK, and Canada is defined as exactly 250 milliliters. It is classified as a Non-SI unit (culinary, metric countries).
Where it's used: Australia, New Zealand, United Kingdom, Canada (recipes and cooking measurement)
Metric cup vs. US cup. The metric cup (250 mL) is about 4% larger than the US cooking cup (240 mL) — small for most recipes, but worth checking when following a recipe from a different country.
Uses of the Metric cup today
- Recipe and cooking measurement in metric-using English-speaking countries
- Baking and portion measurement
History of the Metric cup
As Commonwealth countries metricated through the 20th century, cookbook publishers and standards bodies adopted a round 250 mL 'metric cup' so recipes could use a convenient, easily-scaled volume rather than the US's 240 mL or older imperial teacup conventions.
Historical origin. Metric cup was not the invention of a single named person; it developed through the process described above.
