About these units
Tablespoon (US) (tbsp)
The US tablespoon is defined as 14.7868 mL, though commonly rounded to 15 mL in nutritional labeling and informal cooking contexts. In American cooking, the tablespoon is indispensable for measuring oils, spices, and small liquid quantities. It is also widely used in medicine for dosing liquid medications at home, though modern practice increasingly recommends milliliters for clarity. Its relationship—3 teaspoons = 1 tablespoon and 16 tablespoons = 1 cup—allows American cooks to scale recipes easily, making it a cornerstone unit of the US culinary measurement system.
Teaspoon (UK) (tsp (UK))
The UK teaspoon is defined as 5 milliliters, a value adopted in modern culinary and medical standards. Historically, however, its size varied considerably, often ranging from 4 to 6 mL depending on household spoons, region, or era. The modern 5 mL standardization brought consistency to recipes, pharmaceutical dosing instructions, and food labeling. Because teaspoons were once everyday household items rather than calibrated instruments, the move toward fixed metric equivalents significantly improved recipe reliability and medical accuracy. Despite the shift to SI units, the teaspoon endures as a culturally intuitive volume measure used in cooking and oral medication dosing, tying contemporary practice to long-standing domestic traditions.
