Tablespoon

A tablespoon (tbsp., Tbsp., Tb., or T.) is a large spoon and a cooking measure of volume. In many English-speaking regions, the term now refers to a large spoon used for serving. In some regions, it is the largest type of spoon used for eating.

Several systems of units of measurement define a tablespoon. The most common definition used in the UK, and US is exactly 15 mL. An Australian metric tablespoon is 20 mL. Historically, a United States customary liquid tablespoon was approximately 14.8 mL, or 1⁄2 US fluid ounce; A British tablespoon was approximately 14.2 mL, exactly 1⁄2 imperial fluid ounce.

The capacity of the utensil, as opposed to the measurement, is defined by neither law nor custom but only by preferences, and may or may not significantly approximate the measurement.
