Vitamin D, 25-OH

Vitamin D, 25-OH: ng/mL to nmol/L

US labs print vitamin D, 25-OH in ng/mL, most European labs in nmol/L. To convert, multiply ng/mL by 2.496; to go back, divide nmol/L by 2.496.

nmol/L = ng/mL × 2.496 · molar mass 400.64 g/mol

This converter changes units only. It doesn’t tell you whether a number is in or out of any range: that depends on the range printed by your own lab, and on your doctor. Soma does not diagnose and is not medical advice.

The formula

ng/mL → nmol/L: nmol/L = ng/mL × 2.496
nmol/L → ng/mL: ng/mL = nmol/L ÷ 2.496
Where 2.496 comes from: ng/mL counts the weight of vitamin D, 25-OH in a volume of blood, nmol/L the number of molecules. One mole of calcifediol, 25-hydroxyvitamin D₃ weighs 400.64 g; with that and the difference in volume, one nmol/L is 0.40064 ng/mL.

About the test

Vitamin D, 25-OH, is the main form used to assess the body’s vitamin D. It depends on sunlight, so it is usually lower in winter.

About the vitamin D, 25-OH test · Vitamin D Test — MedlinePlus (U.S. National Library of Medicine).

Questions

How do I convert vitamin D, 25-OH from ng/mL to nmol/L?

Multiply ng/mL by 2.496. For example, 30 ng/mL is 74.9 nmol/L.

How do I convert vitamin D, 25-OH from nmol/L to ng/mL?

Divide nmol/L by 2.496. For example, 150 nmol/L is 60.1 ng/mL.

Why is the factor 2.496?

It follows from the molar mass of calcifediol, 25-hydroxyvitamin D₃, 400.64 g/mol, and from the volume each unit counts in.

Soma converts straight from the PDF

Share a lab report to Soma, and it reads every row on your phone and converts the units for you, so a Quest result in mg/dL and a Synlab result in mmol/L sit on one chart, each against its own lab’s range. No account, nothing uploaded.
