About Converting Deciliters to Milliliters
Deciliter and Milliliter appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Specifically: Deciliter is 0.1 liter units, and milliliter is 0.001 liter units.
Formula
milliliters = deciliters × 100
This factor comes from each unit's defined relationship to the category's base unit: 1 deciliter equals 0.0001 base units, and 1 milliliter equals 0.000001 base units, so dividing one by the other gives the direct deciliter-to-milliliter factor of 100.
Simple example
1 dL × 100 = 100 mL
1 deciliter = 100 milliliters.
Real-world example
10 dL × 100 = 1,000 mL
10 deciliters = 1,000 milliliters.
Conversion table

Reverse conversion: Milliliter to Deciliter
100 mL × 0.01 = 1 dL
100 milliliters = 1 deciliters.
deciliters = milliliters × 0.01

Understanding the Deciliter (dL)
Deciliter is 0.1 liter units.
Understanding the Milliliter
Milliliter (mL) measures volume. A milliliter is one-thousandth of a liter, equal to one cubic centimeter. It is classified as a SI derived (metric prefix) unit.
Where it's used: Standard small-volume unit worldwide
Uses of the Milliliter today
- Medicine dosing (worldwide, including in the US)
- Cooking and recipe measurement outside the US
- Beverage and small-container labeling
History of the Milliliter
The milliliter follows directly from the liter via the 'milli-' SI prefix. It is notable as one of the few metric units in routine US use, since medicine dosing (syringes, liquid medication) is specified in milliliters even in the US.
Historical origin. Milliliter was not the invention of a single named person; it developed through the process described above.
Milliliter — sources
- BIPM SI Brochure — SI prefixes — Defines 'milli-' as the prefix for 10⁻³.

Frequently asked questions
How many milliliters are in 1 deciliter?
1 deciliter equals 100 milliliters, using the exact defined conversion factor rather than an estimate.
How do I convert deciliter to milliliter?
Multiply the deciliter value by 100. The converter above does this instantly to whatever precision you set.
How do I convert milliliter back to deciliter?
Use the reverse factor: 1 milliliter equals 0.01 deciliters. You can also use the swap control in the converter above to flip the direction instantly.
What is a deciliter?
Deciliter (dL) is a unit of volume.
What is a milliliter?
Milliliter (mL) measures volume. A milliliter is one-thousandth of a liter, equal to one cubic centimeter. It is classified as a SI derived (metric prefix) unit.
Is the deciliter to milliliter conversion exact?
Yes. Both deciliter and milliliter are defined by fixed standards rather than physical artifacts, so the factor of 100 used above is exact to as many digits as you choose to display.
