Free T4: ng/dL to pmol/L

US labs print free T4 in ng/dL, most European labs in pmol/L. To convert, multiply ng/dL by 12.872; to go back, divide pmol/L by 12.872.

Value

ng/dL

Same value in15.4pmol/L

pmol/L = ng/dL × 12.872 · molar mass 776.87 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/dL → pmol/L: pmol/L = ng/dL × 12.872
pmol/L → ng/dL: ng/dL = pmol/L ÷ 12.872
Where 12.872 comes from: ng/dL counts the weight of free T4 in a volume of blood, pmol/L the number of molecules. One mole of thyroxine weighs 776.87 g; with that and the difference in volume, one pmol/L is 0.077687 ng/dL.

About the test

Free T4 is the thyroid’s main hormone in its free form, not bound to proteins, which the tissues can use.

About the free T4 test · Thyroxine (T4) Test — MedlinePlus (U.S. National Library of Medicine).

Questions

How do I convert free T4 from ng/dL to pmol/L?

Multiply ng/dL by 12.872. For example, 1.2 ng/dL is 15.4 pmol/L.

How do I convert free T4 from pmol/L to ng/dL?

Divide pmol/L by 12.872. For example, 18 pmol/L is 1.4 ng/dL.

Why is the factor 12.872?

It follows from the molar mass of thyroxine, 776.87 g/mol, and from the volume each unit counts in.
