Tablespoons and teaspoons to milliliters calculator

Type a count and pick a tablespoon or a teaspoon. A tablespoon is 15 ml, a teaspoon is 5 ml. Three tablespoons are 45 ml. Three teaspoons are 15 ml, the same as one tablespoon. Half a tablespoon is 7.5 ml. US in the header changes the writing, not 15 to 14.79.

Cup: cup to mass. Servings: recipe scaling. Oven: baking temperature.

How it works

A tablespoon is 15 ml, a teaspoon is 5 ml. Three tablespoons are 45 ml. Three teaspoons are 15 ml, the same as one tablespoon. Six teaspoons are 30 ml, the same as two tablespoons. Half a tablespoon is 7.5 ml. These are metric kitchen spoons, not the US tablespoon of 14.79 ml.

The US switch does not change 15 to 14.79. It only changes how the result is written: a small volume goes to fl oz instead of ml. 15 ml is about 0.51 fl oz. The cup page next door scales 250 to 240. The tablespoon here stays 15.

There is no product density. Oil, honey, and vinegar share the same volume on a spoon and a different mass. For sugar or flour mass, open the cup page: 200 g and 130 g on 250 ml. Here we only count milliliters.

Zero spoons give zero milliliters. A negative count will not run. If you do not type a count, the calculator has nothing to multiply by 15 or 5. Half a teaspoon is 2.5 ml. Two and a half tablespoons are 37.5 ml.

Three teaspoons are not a pinch. We do not have a pinch in the table. If the recipe says teaspoon, take 5 ml, not 15. If it says tablespoon, take 15 ml, not 5.

When you want to scale those 45 ml to another serving count, open recipe scaling. Leave oven heat on the baking page. The 250 ml cup is next door when a recipe has moved from spoons to cups.

How to use

  1. Type a count, for example 3, and pick a tablespoon or a teaspoon.
  2. Click Calculate. Three tablespoons are 45 ml. Three teaspoons are 15 ml, the same as one tablespoon.
  3. On US you will see fl oz, but 15 ml stays 15 ml. We do not drop to 14.79.
  4. Zero gives zero milliliters. A negative count will not run. Half a tablespoon is 7.5 ml.
  5. A cup of sugar at 200 g is on the neighbouring page. Scaling 45 ml to other servings lives on recipe scaling.

Formula

volume = count × 15 ml (tablespoon) or × 5 ml (teaspoon)

Count ≥ 0. US changes the writing (ml / fl oz), not the spoon size.

Tablespoon 15 ml and teaspoon 5 ml

Volume = count × 15 ml or × 5 ml. Three tablespoons are 45 ml. Three teaspoons are 15 ml, the same as one tablespoon.

Ways to use this calculator

  • You add tablespoons of oil from a recipe into milliliters before you pour from a marked bottle.
  • You check that three teaspoons make one tablespoon when only a teaspoon is left in the drawer.

Frequently asked questions

How many ml are three tablespoons, and three teaspoons?

Three tablespoons are 45 ml. Three teaspoons are 15 ml, the same as one tablespoon. Six teaspoons are 30 ml, the same as two tablespoons.

How much is half a tablespoon and half a teaspoon?

Does US in the header change 15 ml to 14.79 ml?

No. The measures stay 15 and 5. US only changes the writing, usually to fl oz. 15 ml is about 0.51 fl oz, and three tablespoons stay 45 ml.

Do oil and honey weigh the same on a spoon?

The volume is the same, 15 ml per tablespoon. The mass is not, because there is no product density here. Three tablespoons of oil and three of honey are the same 45 ml.

Where is a cup of sugar at 200 g or flour at 130 g?

On cup to mass. That is 250 ml, not 15 ml. A spoon here does not weigh sugar: three tablespoons are 45 ml of volume.

Is zero spoons allowed?

Yes. Zero tablespoons give 0 ml. A negative count will not run, so minus three does not make −45 ml.

Are three teaspoons a pinch?

No. We do not have a pinch in the table. A teaspoon is 5 ml, a tablespoon is 15 ml, and three teaspoons equal one tablespoon.

Where do I scale 45 ml to other servings?

On recipe scaling. You paste 45 and change 4 servings to 6, which gives 67.5. Here the spoon stays: three are 45 ml.

Does a comma in 2.5 work?

Yes. 2.5 and 2,5 are the same number. Two and a half tablespoons are 37.5 ml, and two and a half teaspoons are 12.5 ml.

Is a 250 ml cup 16 tablespoons and a teaspoon?

250 / 15 does not come out even, because 16 × 15 = 240 ml. Count a cup on the neighbor page, not as a stack of 15 ml spoons.
