🍳 Kitchen & Cooking Conversion

Convert culinary volume measurements between US recipe standards and metric kitchen measures: cups, tablespoons (tbsp), teaspoons (tsp), fluid ounces (fl oz), milliliters (mL), pinches, and dashes. Perfect for baking, doubling dinner recipes, and converting international cookbooks.

Culinary conversion calculates volumetric and mass recipe measures across US Customary, UK Imperial, and Metric systems. Based on international culinary standards, 1 US tablespoon equals 3 teaspoons (14.79 mL), 1 US cup equals 16 tablespoons (236.59 mL or 8 fl oz), and 1 metric culinary cup is standardized as exactly 250 mL.

Metrological Standards & Base Equation

1 US Cup = 16 tablespoons = 48 teaspoons = 240 mL = 8 fl oz. 1 tablespoon = 3 teaspoons = 15 mL.

Culinary volume factors comply with NIST Handbook 44 and standard culinary reference tables, noting regional variations between US Customary cups (236.59 mL), legal nutrition labeling cups (240 mL), and Commonwealth metric cups (250 mL).
