Given the rationale, provide a reasonable question and answer. Step-by-step reasoning process: To answer this question, we should know that: The unit of measurement varies by region: a United States tablespoon is approximately 14.8 ml (0.50 US fl oz), a United Kingdom and Canadian tablespoon is exactly 15 ml (0.51 US fl oz), and an Australian tablespoon is 20 ml (0.68 US fl oz).
The question and answer:
A tablespoon is a large spoon used for serving or eating. In many English-speaking regions, the term now refers to a large spoon used for serving, however, in some regions, including parts of Canada, it is the largest type of spoon used for eating. By extension, the term is used as a measure of volume in cooking. In this capacity, it is most commonly abbreviated tbsp or T, and occasionally referred to as a tablespoonful to distinguish it from the utensil. The unit of measurement varies by region: a United States tablespoon is approximately 14.8 ml (0.50 US fl oz), a United Kingdom and Canadian tablespoon is exactly 15 ml (0.51 US fl oz), and an Australian tablespoon is 20 ml (0.68 US fl oz). The capacity of the utensil (as opposed to the measurement) is not defined by law or custom and bears no particular relation to the measurement.
