Converts between cups, tablespoons, teaspoons, and millilitres when following recipes from different countries.
Converts US cups to metric ml when cooking from American cookbooks with a European kitchen.
Calculates exact portion sizes in ml or fl oz from recipe measurements for dietary analysis.
Converts between fl oz, ml, and tablespoons for cocktail recipe scaling.
Scales recipes up to litres for large-batch cooking from cup-based recipes.
Provides both cup and ml measurements in recipes to serve both US and international audiences.
The US tablespoon is defined as exactly 14.7868 mL (½ fl oz). It equals 3 US teaspoons. The word 'tablespoon' dates to the 18th century when spoons were standardized by size relative to cutlery.
Tablespoon sizes vary internationally: US = 14.79 mL; Australian = 20 mL; UK = 17.76 mL (traditional). These differences matter for strong flavors: a US vs Australian tablespoon of salt differs by 35%.
Interesting fact: Before standardized measuring spoons, recipes called for 'a tablespoon of butter' or 'a dessertspoon of sugar' using common cutlery. These were wildly inconsistent — silverware tablespoons ranged from 12 to 18 mL — making old recipes notoriously unreliable.
The US teaspoon is defined as exactly 4.92892 mL (1/6 fl oz = 1/3 tablespoon). It is the smallest standard cooking measure and is used for spices, leavening agents, extracts, and salt where precise small quantities matter.
1 US tablespoon = 3 US teaspoons = 4.929 mL. Baking powder is typically used at 1 tsp per cup of flour; salt at ¼–½ tsp; vanilla extract at 1 tsp. The teaspoon is where measurement precision matters most.
Interesting fact: The metric equivalent of 1 teaspoon is 5 mL — conveniently close to the US teaspoon (4.929 mL). Most medicine dosing spoons and children's medicine cups are calibrated in 5 mL increments for this reason.
The US cup chain: 1 cup = 16 tbsp = 48 tsp = 8 fl oz = 236.6 ml = ½ pint. Note: metric cups (Australia) = 250 ml; UK tablespoon = 17.76 ml vs US 14.79 ml. Always check which measurement system a recipe uses.
