Homework Help: Converting Kcal/day to umol/g/h

  1. Mar 21, 2010 #1
    1. The problem statement, all variables and given/known data
    *Sorry, I got the prefix in the subject wrong... it's supposed to be KCal/day to mmol/g/h, not micromoles
    How do I convert kilocalories/day to millimoles/g/h?

    2. Relevant equations
    Obviously there are 24 hours in a day, but I don't know how to go from KCal to millimol/g

    Presumably you have some reaction(s) to which you want to apply this to? Do you have any enthalpy or free energy changes available?

    Re: Converting Kcal/day to mmol/g/h

    No, it's not a chemical reaction. We're working with Basal Metabolism Rates (BMR) in physiology right now, where BMR is measured in kilocalories/day. I need to convert it to millimoles/g/h to apply it to the weight of a mouse.
    So I just need to know how to convert the units.

    Well, do you know what it is you're metabolising?

    If you have a reaction that gives off e.g. 100 kcal / mol, and that the molecular weight of your substrate is e.g 500 g / mol, you can say that the reaction gives off 0.2 kcal / g. Not sure if that helps?
