Testosterone converter
Convert a total testosterone between ng/dL and nmol/L, with the whole chart below.

- In nmol/L
- 15.6 nmol/L

nmol/L = ng/dL ÷ 28.84450 ÷ 28.84 = 15.60 nmol/LThe AUA uses about 300 ng/dL (10.4 nmol/L) as the cutoff for low testosterone in men, on two early-morning tests.
Two units, one test
US labs print testosterone in ng/dL; most other countries use nmol/L. Divide ng/dL by 28.84 to get nmol/L, and multiply to go back.
The cutoff guidelines use
The American Urological Association uses a total testosterone under about 300 ng/dL (10.4 nmol/L), on two separate early-morning tests, together with symptoms, as its line for low testosterone in men. Ranges for women are far lower and are usually reported the same way.

Questions
How do I convert ng/dL to nmol/L?
Divide by 28.84. 300 ng/dL is about 10.4 nmol/L.
How do I convert nmol/L to ng/dL?
Multiply by 28.84. 15 nmol/L is about 433 ng/dL.
Does free testosterone convert the same way?
No. Free testosterone is reported in pg/mL or pmol/L; the free testosterone calculator handles it.
