1 dl = 100 ml exactly. This is a base metric relationship: deci- means one-tenth, so 1 dl = 1/10 litre = 100 ml.
| Decilitre (dl) | Millilitre (ml) |
|---|---|
| 0.5 dl | 50 ml |
| 1 dl | 100 ml |
| 1.5 dl | 150 ml |
| 2 dl | 200 ml |
| 3 dl | 300 ml |
| 4 dl | 400 ml |
| 5 dl | 500 ml |
| 6 dl | 600 ml |
| 8 dl | 800 ml |
| 10 dl | 1000 ml |
The decilitre (dl) and millilitre (ml) are both metric units of volume, related by a factor of 100. The prefix "deci-" means one-tenth, so 1 dl = 0.1 litre = 100 ml. This is a pure metric relationship — no approximation needed.
Decilitres are widely used in Scandinavian home cooking — a Nordic recipe might call for "3 dl mjölk" while a German recipe would say "300 ml Milch". The numbers are the same; only the unit name differs. Many measuring jugs used in Nordic countries have dl markings alongside ml.
In scientific and medical contexts, ml is more common than dl. However, for everyday cooking volumes (100–1000 ml), the dl scale gives convenient single- or double-digit numbers: 2.5 dl is easier to say than 250 ml, even if they mean the same thing. This converter handles both directions — dl to ml and ml to dl.
1 dl equals exactly 100 ml.
500 ml equals 5 dl.
1 litre equals 10 dl.
