Teaspoons, tablespoons, and ml — what's the difference?

A UK teaspoon is 5 ml and a UK tablespoon is 15 ml. American recipes often use cups (240 ml US, 250 ml metric). If you're following a recipe that uses cups but your measuring jug is in ml — or vice versa — this converter shows all four at once so you never have to do the maths mid-bake.

How to convert teaspoons to ml

1 teaspoon = 5 ml. 1 tablespoon = 15 ml = 3 teaspoons. 1 metric cup = 250 ml.

01

TSP to ML

Multiply teaspoons by 5. Example: 3 tsp × 5 = 15 ml = 1 tablespoon.

02

TBSP to ML

Multiply tablespoons by 15. Example: 2 tbsp × 15 = 30 ml.

03

ML to TSP

Divide ml by 5. Example: 20 ml ÷ 5 = 4 teaspoons.

Conversion formulas

1 tsp = 5 ml | 1 tbsp = 15 ml | 1 cup = 250 ml

These are UK/metric standards. Note: US tablespoon is 14.79 ml (effectively the same). Australian tablespoon is 20 ml — be aware when using Australian recipes.

Tips & Best Practices

  • Medicine is often prescribed as '5 ml spoonfuls' — this is exactly 1 teaspoon

  • For salt in baking: 1 tsp = 6g, ½ tsp = 3g

  • Always use level measurements unless a recipe specifies heaped

  • US cups are 240 ml, metric cups are 250 ml — most UK recipes use metric
