Converting Estradiol (E2) from Canadian to American values

How do I convert my Canadian Estradiol (E2) numbers to American measurements?
In Canada E2 levels are measured in picomols and in the United States E2 levels are measured in picograms.

If you want to compare numbers, here is how to convert them:

Canadian E2 ÷ 3.67 = American E2
American E2 x 3.67 = Canadian E2
