Convert deciliters ⇄ milliliters

250 ml
2.5 dl = 250 ml (metric (SI) units)

Formula: 2.5 dl × 100 = 250 ml

How the dl to ml conversion works

The conversion is exact: millilitres = deciliters × 100. The SI prefix "deci-" means one-tenth, so a decilitre is one-tenth of a litre — and since a litre is 1,000 ml, one decilitre is exactly 100 ml. Going the other way, deciliters = millilitres ÷ 100.

Worked example: a Scandinavian baking recipe calling for 2.5 dl of milk needs 2.5 × 100 = 250 ml. And 300 ml of stock is 300 ÷ 100 = 3 dl.

Handy benchmarks: 1 dl = 100 ml, 2 dl = 200 ml, 2.5 dl = 250 ml, 5 dl = 500 ml and 10 dl = 1 litre. For the smaller metric step, see our centiliters to ml converter, and for US cups see deciliters to cups.

deciliters to milliliters questions

How many ml are in a deciliter?
Exactly 100 ml. The decilitre is one-tenth of a litre, and a litre is 1,000 ml, so 1,000 ÷ 10 = 100 ml — an exact conversion, no rounding.
How do I convert dl to ml?
Multiply by 100: ml = dl × 100. So 2 dl is 200 ml, 2.5 dl is 250 ml and 5 dl is 500 ml. Type any figure above.
How many ml is 2.5 dl?
250 ml — a quarter of a litre. It is one of the most common figures in Scandinavian baking, where 2.5 dl of flour or milk appears in recipe after recipe.
Why do European recipes use dl?
The decilitre is the standard kitchen volume in Scandinavia and much of continental Europe, the way the US cup is in American recipes. A recipe in dl converts to ml by multiplying by 100 — no ingredient density needed, because both are pure volume units.
How do I convert ml back to dl?
Divide by 100: dl = ml ÷ 100. So 250 ml is 2.5 dl and 1,000 ml is 10 dl. Switch the direction above to do it.
