# Converting Kcal/day to umol/g/h

## Homework Statement

*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?

## Homework 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?

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?
