This g/L to g/dL calculator converts between grams per liter and grams per deciliter. Unlike molar conversions, this conversion does not depend on molecular weight. It is only a liter to deciliter volume conversion. If you need milligrams per deciliter instead, use the g/L to mg/dL calculator.
Since 1 liter equals 10 deciliters, a value in grams per liter is 10 times the matching value in grams per deciliter. For example, 100 g/L equals 10 g/dL.
This conversion is common when comparing lab reports from different regions or systems. Some reports use g/L for protein-style measurements, while others use g/dL for the same type of concentration.

g/L to g/dL Formula
To convert grams per liter to grams per deciliter, divide the g/L value by 10.
g/dL = g/L / 10 For example, if a lab value is 140 g/L, the calculation is 140 / 10 = 14 g/dL.
Why You Divide by 10
The gram unit does not change in this conversion. Only the volume unit changes from liters to deciliters. A deciliter is one-tenth of a liter, so there are 10 deciliters in 1 liter.
100 g/L = 100 g / 10 dL = 10 g/dL This is why the conversion is much simpler than molar lab conversions. You do not need molecular weight, and you do not need to know which molecule is being measured.
g/dL to g/L Formula
To convert grams per deciliter back to grams per liter, multiply the g/dL value by 10.
g/L = g/dL x 10 Common Lab Examples
These examples show the same concentration written in g/L and g/dL. They are unit conversions only, not clinical reference ranges.
| Example value | Converted value | Calculation |
|---|---|---|
| 35 g/L | 3.5 g/dL | 35 / 10 |
| 60 g/L | 6 g/dL | 60 / 10 |
| 100 g/L | 10 g/dL | 100 / 10 |
| 140 g/L | 14 g/dL | 140 / 10 |
For example, 13.5 g/dL equals 13.5 x 10 = 135 g/L.

Where g/L and g/dL Are Used
g/L and g/dL are both mass concentration units. They may appear on lab reports for values such as hemoglobin, albumin, total protein, and other measurements where a mass of substance is reported per volume of fluid.
Different countries and laboratories may use different reporting styles. One report may show hemoglobin in g/L while another shows it in g/dL. The conversion is simple, but interpretation still depends on the lab reference range and clinical context.
g/L vs g/dL vs mg/dL
The unit names are similar, but the conversion factors are not the same. Check both the mass unit and the volume unit before converting.
- g/L to g/dL: divide by 10.
- g/dL to g/L: multiply by 10.
- g/L to mg/dL: multiply by 100.
- mg/dL to g/L: divide by 100.
Common Conversion Mistakes
A common mistake is converting g/L to mg/dL when the report or reference range actually uses g/dL. For example, 100 g/L is 10 g/dL, but it is 10,000 mg/L and 1000 mg/dL. Those are very different-looking numbers, even though they may describe the same concentration in different units.
Another mistake is comparing a converted value with a reference range in the old unit. Convert the result and the reference range into the same unit before comparing them.

This page is for unit conversion only. It does not interpret lab results, diagnose conditions, or replace medical advice. Always compare results with the reference range from the same lab and consult a healthcare provider for interpretation.
Frequently Asked Questions
How do you convert g/L to g/dL?
Divide the g/L value by 10. For example, 100 g/L equals 10 g/dL.
How do you convert g/dL to g/L?
Multiply the g/dL value by 10. For example, 14 g/dL equals 140 g/L.
Is g/L to g/dL molecule-specific?
No. g/L to g/dL is not molecule-specific because both units measure mass concentration. The only difference is liter versus deciliter.
What is 150 g/L in g/dL?
150 g/L equals 15 g/dL.
Why does 100 g/L equal 10 g/dL?
Because 1 liter contains 10 deciliters. Divide 100 grams per liter by 10 deciliters to get 10 grams per deciliter.
Is g/L the same as g/dL?
No, the units are different. They can describe the same concentration after conversion: 10 g/dL equals 100 g/L.
Is g/L to g/dL the same as g/L to mg/dL?
No. g/L to g/dL divides by 10. g/L to mg/dL multiplies by 100 because the mass unit changes from grams to milligrams while the volume unit changes from liters to deciliters.
