Often between 300 and 500ml but it varies greatly. A serving of soup is generally quoted as 250ml or a U.S. cup (8oz). Many restaurants serve about this amount in a bowl capable of holding much more.
The unit used to measure the capacity of a soup pot is typically in liters (L) or milliliters (mL) for smaller pots. Capacity refers to the maximum volume of liquid the pot can hold. It is important to use the appropriate unit of measurement to accurately determine the volume of the pot and the amount of soup it can contain.
