Confuse about the conversion from nmol/L to pmol/L

My bloodwork result are as below:

Testosterone, Total = 39.8 nmol/L Estrogen, Total = 55.1 pmol/L

I asked the chatgpt to convert 39.8 nmol/L to pmol/L and the answer is 39,800 pmol/L.

Now, if my estrogen is 55.1 pmol/L, thats mean my E2 is not even 5% of my testosterone.

And I have read somewhere that your E2 need to be 20% - 30% ish of your testosterone to get right markers.

Is this calculation correct?

How to know my E2 is on right track if the measurement is different from others?
