About This Calculator
This testosterone converter supports conversion between nmol/L and ng/dL using a fixed factor based on testosterone’s molecular weight (288.42 g/mol). It's widely used in endocrinology to standardize lab results across unit systems.
How It Works
- Select the conversion direction: nmol/L to ng/dL or ng/dL to nmol/L.
- Enter the testosterone value in the selected unit.
- The result is calculated using these formulas:
ng/dL = nmol/L × 28.84
nmol/L = ng/dL ÷ 28.84
Note: The factor 28.84 is specific to testosterone, based on molecular weight 288.42 g/mol.
Frequently Asked Questions
Can I convert both directions?
Yes. This calculator supports both nmol/L to ng/dL and ng/dL to nmol/L.
What is the formula based on?
It is derived from the molecular weight of testosterone: 288.42 g/mol.
Is this tool suitable for clinical use?
Yes. It applies standard formulas used in clinical endocrinology.
Does this apply to other hormones?
No. Each hormone has its own molecular weight and conversion factor.
What are normal testosterone levels?
Typical adult male range is 300–1000 ng/dL or 10.4–34.7 nmol/L, depending on lab reference.
