Fractions and proportions (en tredjedel, hälften)

Adjusting the Recipe

When cooking, you often need to change the size of a recipe. Verbs like dubbla (to double), halvera (to halve), and dela (to divide) come in handy when adjusting mängden (the amount) or dealing with resten (the rest) of your ingredients.

I double the recipe because the amount is too small.
Jag dubblar receptet eftersom mängden är för liten.
You must halve the amount of sugar.
Du måste halvera mängden socker.
We must divide the rest of the dough into three pieces.
Vi måste dela resten av degen i tre bitar.

Kitchen Measurements

Swedish recipes frequently rely on volume rather than weight for dry ingredients. You will see a lot of deciliter (often abbreviated as "dl") and liter.

Are there two deciliters or a liter of milk left?
Finns det två deciliter eller en liter mjölk kvar?

Fractions with -del

To express a mathematical fraction, Swedish attaches the suffix -del (part/share) to the ordinal number.

  • en tredjedel (a third)
  • en fjärdedel (a fourth/quarter)

When you need more than one of that fraction, treat -del like a normal noun and add its plural ending -ar to make -delar (e.g., två tredjedelar). Use the preposition av to say "a fraction of something".

We cut the onion and add a third of it to the pot.
Vi skär löken och tillsätter en tredjedel av den i kastrullen.
It is the same recipe, but we only use a quarter of the butter.
Det är samma recept, men vi använder bara en fjärdedel av smöret.
I divide the cake, so you get two thirds.
Jag delar kakan, så du får två tredjedelar.

Hälften vs. En halv

When talking about halves, Swedish has two distinct words depending on the grammar of the sentence:

Hälften is a definite noun meaning "the half". You use it to talk about a specific proportion of a whole, usually followed by av (of).

En halv (or ett halvt for ett-words) is an adjective meaning "a half". You use it directly before a noun when counting or measuring.

He always eats half of the cake himself.
Han äter alltid hälften av kakan själv.
We need two and a half deciliters of flour.
Vi behöver två och en halv deciliter mjöl.
