  • pmol/L to ng/dL

    Can someone help me out with converting estradiol (or oestradiol) from pmol/L to ng/dL? I should know this, but I just can't figure it out and am going around and around in circles - gah! Thanks in advance!

    To convert between moles and grams, you need molar mass of the substance. Wikipedia says 272.38 g/mol for estradiol. Then you need some adjustments of prefixes

    1 pmol/L x 272.38 g/mol x 1 ng/1000 pg x 1L/10 dL = 0.027238 ng/dL
