Deciliters to Liters (dL to L)

1 deciliter equals 0.1 liters exactly.

1 deciliter = 0.1 liters

How to convert deciliters to liters

To convert deciliters to liters, multiply the number of deciliters by 0.1. This factor is exact. To go the other way, multiply liters by 10.

liters = deciliters × 0.1

Example: 10 deciliters = 1 liter.

Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.

About these units

Deciliter (dL)

Metric (SI)Current unit

One tenth of a liter (100 mL). Common in recipes in Scandinavia and Switzerland.

Cookbooks and menus in Croatia, Switzerland and the Scandinavian countries still measure with the deciliter, writing recipes in dL where an American cook would reach for a cup. A deciliter is one tenth of a liter, so it holds 100 cubic centimeters, or 100 milliliters, and it is a little under half of a US customary cup.

The prefix deci- means one tenth. In practice the unit suits a household portion between a spoon and a full liter. Ten deciliters make a liter, and ten centiliters make a deciliter, so conversion needs only a shifted decimal point. The figure used here is exactly 0.1 liter. For scale, five deciliters make half a liter, and one deciliter is 100 times a single milliliter.

1 deciliter = 0.1 liters (exactly).

Liter (L)

Metric (SI)Current unit

One cubic decimeter (1,000 cm³). The everyday metric unit of volume for drinks, fuel and cooking.

The liter was born in revolutionary France. In 1795 it was introduced as a republican unit and defined as one cubic decimeter, while the gram was tied to a cubic centimeter of water. The name comes from the older French litron, itself descended from a Byzantine Greek unit of weight, not volume. A small revision of the decimeter in 1798 left the first liter about 1.000974 of today's cubic decimeter, and in 1879 the international metric authorities adopted the liter with the symbol l.

The liter then took a strange detour. In 1901 it was redefined as the space taken up by one kilogram of pure water at its densest, which made it about 1.000028 cubic decimeters, and that muddled definition lasted until 1964, when it was restored to exactly one cubic decimeter. A capital L was added as an alternative symbol in 1979 because a lowercase l is easy to mistake for the digit 1, and NIST says L is the symbol to use in the United States. A liter of water is close to a kilogram, which is why a one-liter bottle feels like a kilo in the hand.

The liter is the reference unit for volume on this site.
