    See my response below to another post. I found values for kcal per grams glucose of 3.35 to 3.8. I have always used 4 as an average. Using 4 kcal/g you have
    g glucose in 2700 mL at 4g/100 mL you have infused 4 x (2700/100) = ?g glucose.
    Then kcal = 4 or whatever your notes/book give you for glucose x ?g glucose from above.

    To convert kcal to joules, multiply by 1000 x 4.184 J/cal
