How it works
Pick the ingredient
For weight, choose the ingredient: flour, sugar and butter weigh differently.
Read the result
The result is shown in grams, millilitres or the unit you choose.
How many ml are in a teaspoon?
One US teaspoon is 4.93 ml, and recipes and medicine labels round it to 5 ml, the same as the metric teaspoon. To convert, multiply the number of teaspoons by 4.93: 2 teaspoons are 9.9 ml and 3 teaspoons, one tablespoon, are 14.8 ml. The converter above does it for any amount and shows fluid ounces as well.

Why it matters
Small amounts matter most in a recipe: baking powder, yeast, salt and spices are added by the teaspoon, and a wrong measure can spoil a bake. With medicine, use the measuring device that comes with it, never a kitchen spoon.
How it is calculated
The US teaspoon is a third of a tablespoon, 4.92892 ml. The tool multiplies the number of teaspoons by that figure and shows the result to one decimal place.
