Why do different laboratories report estradiol in different units?

Different laboratories and countries use different measurement systems.

Some report estradiol in pg/mL (picograms per millilitre), while others use pmol/L (picomoles per litre).

The result represents the same hormone concentration—only the unit of measurement is different, much like reporting temperature in Celsius or Fahrenheit.
