mg/dL to mg/L Converter
To convert mg/dL to mg/L, multiply the value in milligrams per deciliter by 10.
How to Convert mg/dL to mg/L
Use this mg/dL to mg/L converter to change milligrams per deciliter into milligrams per liter. Enter the value in mg/dL and read mg/L.
The mass unit (mg) stays the same. Only the volume changes. One liter holds 10 deciliters, so the same substance gives a number 10 times larger per liter. Multiply by 10.
For example, 0.8 mg/dL × 10 = 8 mg/L.
1 mg/dL = 10 mg/LMultiply the value in mg/dL by 10 to get mg/L.Conversion Formula
The formula to convert mg/dL to mg/L is:
Where:
- mg/dL = concentration in milligrams per deciliter
- mg/L = concentration in milligrams per liter

- 50 mg/L = 5 mg/dL
- 330 mg/L = 33 mg/dL
- 1,000 mg/L = 100 mg/dL
Unit Definitions
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.
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.
Why Is the Conversion Factor 10?
A concentration has two parts: an amount on top and a volume below. To find the factor, compare each part separately and then divide.
Therefore, 1 milligram per deciliter equals 10 milligrams per liter. To convert mg/dL to mg/L, you multiply by 10, and to convert mg/L to mg/dL, you divide by 10.
Uses and Importance of mg/dL and mg/L
mg/dL and mg/L are both mass concentrations. Labs and countries choose different volumes, so the same test can appear with different numbers.
C-reactive protein (CRP)
CRP is reported in mg/dL by some labs and in mg/L by others. High-sensitivity CRP (hs-CRP) is usually given in mg/L. Mixing them up gives a tenfold error.
Comparing reports
If an old report used mg/dL and a new one uses mg/L, converting shows whether the value really changed.
Water and environment
Water quality limits are often in mg/L. Converting from mg/dL makes lab data match those limits.
Frequently Asked Questions (FAQ)
Is mg/dL bigger than mg/L?
Yes. 1 mg/dL is the same concentration as 10 mg/L, because a deciliter is one tenth of a liter.
Why do CRP results sometimes differ by ten times?
One lab may report in mg/dL and another in mg/L. For example, 0.5 mg/dL = 5 mg/L. Always check the unit before comparing.
What is a deciliter?
A deciliter (dL) is one tenth of a liter, or 100 mL.
Do I need the molecular weight for this conversion?
No. Both units are mass per volume. Only the volume part changes.
Can I use this for glucose in mg/dL?
Yes, the factor of 10 works for any substance in mg/dL. To convert glucose to mmol/L instead, use this site's mmol/L to mg/dL calculator.

Accuracy and Scope
The factor 1 mg/dL = 10 mg/L is exact because 1 L = 10 dL.
This converter changes units only. It does not interpret CRP or any other result; use your laboratory's reference range.
