Which unit of capacity would be best to measure the amount soup in a bowl?

The best unit of capacity to measure the amount of soup in a bowl would be milliliters (ml).

Here's why:

* Practicality: Milliliters are a common unit for measuring liquids, and most kitchen measuring tools are calibrated in milliliters.

* Accuracy: Milliliters offer a more precise measurement than larger units like liters, which are better suited for larger volumes.

* Convenience: A typical bowl holds a few hundred milliliters of soup, making it a convenient and easily understandable unit.

While you *could* use other units like cups or ounces, milliliters provide the most accurate and commonly used measurement for this scenario.
