Conversion table (US measurements)
- 1 cup = 16 tablespoons (Tbsp) = 48 teaspoons (Tsp) = about 236.6 ml = 8 fl oz
- 1 tablespoon (Tbsp) = 3 teaspoons (Tsp) = about 14.8 ml
- 1 teaspoon (Tsp) = about 4.9 ml
A "cup" isn't the same size everywhere
This calculator is based on the US customary cup (1 cup ≈ 236.6 ml). Note that the "metric cup" used in Australia, the UK, and New Zealand defines 1 cup as exactly 250 ml, and Japan uses 200 ml for 1 cup — conventions vary by country, so when following a recipe from abroad, it's worth checking which standard it's using.

Frequently Asked Questions
Can this convert to grams?
This calculator only converts between volume units. Converting to grams (weight) is difficult to do accurately because density varies by ingredient — it's best to look up an ingredient-specific conversion table instead.
Why do measuring cups differ in size between countries?
Measurement units differ historically because each country set its own standards independently. To reproduce a recipe accurately, it's important to check which country's convention the original recipe was written in.
