How much medicine would be usual dose for a 18 month old weighing 27 pounds
~~~~~~~~~~~~~~~~~~~~~~ 

The dosage should be 5 mg per kilogram of body weight. 

27 lbs. = 27*0.453592 = 12.25 kilograms (rounded).


Regarding the age and the body temperature, we are in the right diapason.  

So, we can apply the given formula


    the medicine amount = 12.25 x 5 mg = 61.25 mg Ibuprofen for 27 lbs. body weight.
