1 nmol/L ≈ 28.84 ng/dL. In the other direction, 1 ng/dL ≈ 0.03467 nmol/L.

How do you convert nmol/L to ng/dL?
For total testosterone, multiply the nmol/L value by approximately 28.842. For example, 12 nmol/L × 28.842 ≈ 346 ng/dL.
The factor comes from testosterone's molecular weight and should not be reused for other hormones.
How do you convert ng/dL to nmol/L?
Multiply the result in ng/dL by approximately 0.0346717. For example, 300 ng/dL is approximately 10.40 nmol/L.
Does the conversion tell me whether my testosterone is low?
No. Unit conversion only allows comparison of values written in different units. Interpretation depends on timing and conditions of the test, the laboratory method, symptoms, repeat testing and, where appropriate, SHBG, calculated free testosterone, LH, FSH and other information.
The EAU 2026 uses 12 nmol/L as a threshold within the diagnosis of late-onset hypogonadism in the appropriate clinical context. That is approximately 346 ng/dL, but 346 ng/dL is not an automatic diagnosis.
Can I use this converter for free testosterone?
This calculator is intended for total testosterone between nmol/L and ng/dL. Free testosterone may be reported in other units such as pmol/L or pg/mL, and interpretation also depends on the measurement or calculation method.
