Hormone unit converter — pmol/L, ng/mL, mIU/L
Search for a hormone and type the result in any unit. For protein hormones, conversion to international units depends on the standard and assay — see the note under the name.
Thyroid
Adrenal
Sex and pituitary hormones
Metabolism and heart
This converter does not include that test.
How we convert
Mass units (mg/dL) are converted to molar units (mmol/L, µmol/L) using the molar mass of the compound: mmol/L = mg/dL × 10 ÷ molar mass. For protein hormones (GH, prolactin, insulin, renin) conversion to international units relies on WHO standards and may differ between laboratories. Results are rounded to about 4 significant digits.
Always use the reference range printed on your laboratory report — it depends on the assay.
