Blood Test Unit Converter
Convert blood test units for glucose, creatinine, CRP, albumin, and more. Switch between mg/dL, mmol/L, and other units, or convert several results together.
Glucose is filled in as an example. Choose a marker and enter the value on your report.
Use exact numeric results. A value such as “<0.1” is a detection limit, not an exact concentration.

90 × 0.05551 = 4.9959
PhenoAge can reuse your albumin, creatinine, glucose, and CRP. You will enter the remaining markers there.

This converts units without interpreting your results. Calculations run in your browser. Passing values to PhenoAge uses temporary storage in this tab.
The conversion depends on the blood-test marker
Choose the marker before entering the value. A mass-to-molar conversion depends on the substance’s molecular mass, so glucose and triglycerides use different factors even when their unit labels look the same.
Match the marker and units
Read both from your report. This tool includes glucose, creatinine, albumin, CRP, triglycerides, calcium, hemoglobin, and ferritin. A value reported as below a detection limit cannot be treated as an exact number.
Convert in either direction
The published factor converts the conventional unit to the SI unit. The reverse calculation divides by the same factor. Displayed values are rounded; calculations keep the extra precision.
conventional value × conversion factor = SI value
Keep related results together
Add rows to convert several markers. Copy the results, or pass compatible albumin, creatinine, glucose, and CRP values to the biological-age calculator within this browser tab. You still need its other required inputs.
Example: creatinine at 1 mg/dL
Multiply by 88.4 to get 88.4 µmol/L. For glucose, the conventional-to-SI factor is 0.05551, so 90 mg/dL is approximately 5.00 mmol/L. A single conversion factor cannot serve both markers.
Common questions
How do I convert glucose from mg/dL to mmol/L?
Multiply by 0.05551. For example, 100 mg/dL is about 5.55 mmol/L. To convert back, divide by the same factor. Dividing by 18 is a commonly used approximation.
How do I convert creatinine from µmol/L to mg/dL?
Divide by 88.4. A result of 88.4 µmol/L becomes 1 mg/dL. This conversion changes the units; it does not interpret kidney function.
Are CRP in mg/L and mg/dL the same?
No. A liter contains ten deciliters, so 0.1 mg/dL equals 1 mg/L. Check which unit your report and the calculator require.
Why does ferritin stay the same number?
One ng/mL equals one µg/L. Both the mass and volume units change by the same factor, so the numerical value stays the same.
Can I convert insulin from pmol/L here?
Insulin is not included. Its activity-to-molar conversion can depend on the assay. Use the laboratory’s documented factor rather than a universal conversion.
Is this a blood-test interpretation?
No. This tool changes units. Reference ranges, sample conditions, assay methods, and the rest of your health information still matter when interpreting a result.
