pg/ml to ng/dl Conversion

[gpetersmarck]

Hi,

My first 3 BW listed my free testosterone using the metric of ng/dL. Doc has switched labs so now it shows as pg/mL. How do I convert that number to ng/dL? I'm trying to see what percentage my free T is of my total T. Forgot to mention, with every BW the total T has been using metric of ng/dL. For example, my most recent results were:

Total T - 838 ng/dL
Free T - 262 pg/mL

How do I figure out what that Free T percentage of is/how do I convert the '262 pg/mL' to a ng/dL metric?

Divide by 10. It's all metric.
