How to Convert mg/L to mg/dL

This mg/L to mg/dL converter changes milligrams per liter into milligrams per deciliter. Enter mg/L to get mg/dL.

A deciliter is one tenth of a liter. So the amount in each deciliter is one tenth of the amount in a liter. Divide by 10.

For example, 12 mg/L ÷ 10 = 1.2 mg/dL.

1 mg/L = 0.1 mg/dLDivide the value in mg/L by 10 to get mg/dL.

Conversion Formula

The formula to convert mg/L to mg/dL is:

mg/dL = mg/L ÷ 10

Where:

mg/L = concentration in milligrams per liter
mg/dL = concentration in milligrams per deciliter

Example Calculation33 mg/L ÷ 10 = 3.3 mg/dL

33 mg/L to mg/dL33 ÷ 10 =3.3 mg/dL

100 mg/L to mg/dL100 ÷ 10 =10 mg/dL

Reverse Conversion Examples (mg/dL to mg/L)

0.1 mg/dL = 1 mg/L

Unit Definitions

What is milligrams per liter (mg/L)?

Milligrams per liter (mg/L) is a unit of mass concentration. It tells you how many milligrams of a substance are present in one liter of liquid.

1 mg/L = 1 mg/L.

What is milligrams per deciliter (mg/dL)?

Milligrams per deciliter (mg/dL) is a unit of mass concentration. It tells you how many milligrams of a substance are present in one deciliter of liquid. One deciliter is 0.1 liter, or 100 milliliters.

1 mg/dL = 10 mg/L.

Why Is the Conversion Factor 0.1?

A concentration has two parts: an amount on top and a volume below. To find the factor, compare each part separately and then divide.

Mass: both use mgVolume: 1 L = 10 dL

1 mg/L = 1 mg ÷ 10 dL = 0.1 mg/dL

Therefore, 1 milligram per liter equals 0.1 milligrams per deciliter. To convert mg/L to mg/dL, you divide by 10, and to convert mg/dL to mg/L, you multiply by 10.

Uses and Importance of mg/L and mg/dL

Many US lab reports use mg/dL, while many other countries and newer tests use mg/L. Converting helps compare results across systems.

CRP and hs-CRP

A value reported as 3 mg/L is the same as 0.3 mg/dL. Knowing this avoids a tenfold misreading.

Drug levels

Some drug concentrations are reported in mg/L; converting to mg/dL matches older references.

Nutrition research

Blood nutrient data can appear in either unit; converting keeps studies comparable.

Frequently Asked Questions (FAQ)

How do I convert mg/L to mg/dL quickly?

Move the decimal point one place to the left. 25 mg/L becomes 2.5 mg/dL.

What is 3 mg/L in mg/dL?

3 ÷ 10 = 0.3 mg/dL.

Why is the mg/dL number smaller than the mg/L number?

A deciliter holds less liquid than a liter, so it holds less of the substance.

Is mg/L the same as ppm?

For dilute water solutions, 1 mg/L is about 1 part per million (ppm) by mass. For blood and other fluids, use mg/L, not ppm.

Is this conversion the same for every test?

Yes, whenever both values are in milligrams. The factor is always 10.
