g/dL g/L mg/dL mg/L

Worked example

3 g/L (middle of the reference range) = 0.3 g/dL

Conversion formulas

g/dL	g/dL = g/L × 0.1	g/L = g/dL × 10
mg/dL	mg/dL = g/L × 100	g/L = mg/dL × 0.01
mg/L	mg/L = g/L × 1000	g/L = mg/L × 0.001

Good to know

Alpha-1 globulin is a protein fraction in serum protein electrophoresis. It is reported in g/dL or in g/L.

g/dL × 10 = g/L; 0.8 g/dL equals 8 g/L.
The fractions add up to the total protein; the printed ranges depend on the laboratory's method.

Reference range

Unit	Adults
g/dL	0.2 – 0.4
g/L	2 – 4
mg/dL	200 – 400
mg/L	2000 – 4000

Frequently asked questions

How do I convert Alpha-1 globulin from g/L to mg/dL?

mg/dL = g/L × 100. In the other direction: g/L = mg/dL × 0.01.

What is the reference range of Alpha-1 globulin?

For adults the range is 2 – 4 g/L (MedlinePlus (NLM): Protein electrophoresis - serum). Reference ranges differ between laboratories and partly by sex and age; use the range printed on your lab report.

Which units are used for Alpha-1 globulin?

Common units are g/dL, g/L, mg/dL, mg/L.
