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 (US) (tsp (US))
The US teaspoon equals 4.92892 mL, though rounded to 5 mL in most practical applications. Before standardization, teaspoon sizes varied widely across households and manufacturers. With the rise of packaged foods, pharmaceuticals, and industrial recipes, the US standardized teaspoon values brought consistency to cooking and medicine. Today, the teaspoon remains the most common household unit for measuring small amounts—especially spices, extracts, and medicines.
