* Units Of Measure *

The international unit of nmol/L (nanomoles per liter) is used in Canada, in the USA they used ng/dL (nanograms per deciliter) - where one mole is 6.02E+23 molecules per Avogadro.

Testosterone has a molecular weight of 288.43 g/mol, so the conversion is

1 nmol/L = (nmol/L)(mol/10^9 nmol)(L/10dL)(288.43g/mol)(10^9ng/g)

1 nmol/L = (1/10^9)(1/10)(288.43)(10^9) ng/dL

1nmol/L = 28.843 ng/dL

In short, the medical unit conversion is 10% of molecular weight.

Therefor:

1nmol/L = 10 % (288.43) ng/dL
1nmol/L = 28.843 ng/dL

*So, multiply your Canadian measurement (6.9 nmol/L) by 28.843 and the results will be the USA unit of measure.(199.01ng/dL) and vice versa. To convert USA measurements to Canadian measurements, you simply divide by 28.843. :)

Good stuff Mickey!
