1 US cup equals 2.4 dl. Since 1 cup = 240 ml and 1 dl = 100 ml, the factor is 2.4 — so ½ cup = 1.2 dl and ¼ cup = 0.6 dl.
| US cup (240 ml) | Decilitre (dl) |
|---|---|
| 0.25 US cup | 0.6 dl |
| 0.5 US cup | 1.2 dl |
| 0.75 US cup | 1.8 dl |
| 1 US cup | 2.4 dl |
| 1.5 US cup | 3.6 dl |
| 2 US cup | 4.8 dl |
| 3 US cup | 7.2 dl |
| 4 US cup | 9.6 dl |
| 5 US cup | 12 dl |
| 8 US cup | 19.2 dl |
When following a US recipe in a Nordic kitchen, the most common conversion need is cups to decilitres. Scandinavian measuring tools are graduated in dl and ml, while American recipes specify cups and tablespoons.
The conversion factor is 2.4: multiply the number of cups by 2.4 to get decilitres. For whole cups this is straightforward — 1 cup = 2.4 dl, 2 cups = 4.8 dl, 3 cups = 7.2 dl. For common fractions: ¼ cup = 0.6 dl, ⅓ cup ≈ 0.8 dl, ½ cup = 1.2 dl, ⅔ cup ≈ 1.6 dl, ¾ cup = 1.8 dl.
Note that Australia and Canada use a "metric cup" of 250 ml = 2.5 dl, not 240 ml. If the recipe is from those countries, adjust accordingly. For dry ingredients like flour or sugar, weighing in grams is always more accurate than converting between volume units.
1 US cup equals exactly 2.4 dl (240 ml ÷ 100 ml per dl).
Half a cup (0.5 cup) equals 1.2 dl.
One quarter cup equals 0.6 dl (60 ml).
