Tablespoons to mL Converter

About this calculator

A US tablespoon is legally and culinarily defined as exactly 14.7868 mL (3 US teaspoons, or 1/16 US cup), a figure that differs slightly from the UK/Australian metric tablespoon (15 mL, sometimes 20 mL in Australia), which is why recipe conversions between countries can subtly throw off a dish if the wrong tablespoon size is assumed.

Home cooks and professional recipe developers rely on tbsp-to-mL conversion constantly when scaling recipes, converting between US-written and metric-written recipes, or measuring precisely with a graduated kitchen tool instead of a spoon — especially important in baking, where volume accuracy affects results more than in general cooking.
