Testosterone is vital for health, influencing muscle growth, energy, and mood. However, differences in measurement units can make interpreting results confusing. This calculator supports conversions across the three most common units:

nmol/L (nanomole per liter) – Common in the UK, Scandinavia, and parts of Europe.
ng/dL (nanograms per deciliter) – Widely used in the USA and Europe.
ng/mL (nanograms per milliliter) – Often found in specific lab results.

The tool simplifies unit conversions, ensuring users can interpret lab results accurately.
