Testosterone Converter (ng/dL ↔ nmol/L)
Convert total testosterone between US ng/dL and SI nmol/L with the 0.0347 factor.
Multiply ng/dL by 0.0347 for nmol/L. Anchors: 500 ng/dL = 17.4 nmol/L, typical adult male range ~300–1000 ng/dL (10.4–34.7 nmol/L). Levels swing markedly through the day (highest at dawn) and with illness, so a single reading rarely tells the whole story — clinicians repeat morning samples. Interpretation is firmly a doctor's job.
