Why this conversion matters in chemistry
US clinical-chemistry reports blood glucose, cholesterol, and creatinine in mg/dL — a 100 mg/dL fasting plasma glucose is the normoglycemia reference. A research-side LC-MS/MS pharmacology study tracking the same analyte runs in mg/L: that 100 mg/dL becomes 1000 mg/L on the bioanalytical worksheet. Where the 10 mg/L per mg/dL comes from: 1 dL = 0.1 L. The conversion sits at the handoff between traditional US clinical-laboratory reporting and SI-aligned research bioanalytical methods.
Formula
mg/L = mg/dL × 10
Worked Examples
1 mg/dL = 10 mg/L
The conversion anchor — the deciliter to liter ratio.
100 mg/dL = 1000 mg/L
Normal fasting blood glucose — the standard clinical reference.
200 mg/dL = 2000 mg/L
Elevated total cholesterol — the borderline-high threshold in US clinical work.
7 mg/dL = 70 mg/L
Upper-end serum creatinine — useful as a renal-function reference.
Frequently Asked Questions
How do I convert mg/dL to mg/L?
Multiply by 10. So 100 mg/dL becomes 1000 mg/L. The relationship is exact through 1 L = 10 dL.
Why does US medicine use mg/dL?
Historical convention — US clinical labs settled on mg/dL for blood chemistry (glucose, cholesterol, creatinine) before international standards consolidated around mmol/L. The convention persists because clinicians have learned the mg/dL reference ranges.
How does mg/dL relate to mmol/L?
mmol/L = (mg/dL × 10) ÷ molecular weight. So 100 mg/dL glucose becomes 1000 mg/L = 1000/180 ≈ 5.6 mmol/L. The molecular weight of the analyte is the bridge factor.
