Convert canine TSH mU/L to ng/ml

Hi...I need to convert canine TSH mU/L to ng/ml. Thanks for your help...Jess

Could someone help me figure out how to convert TSH/thyrotropin from ng/mL into an SI unit such as mIU/L or mmol/L? All the websites I have only have conversion from mIU/L to mIU/L, which of course is 1.0! Not helpful... Thank you very much
