How to convert from one measurement to another measurement

Nurses have to make conversions from one type of measurement to another type of measurement while administering medication to a patient.  Typically, the need for conversions arises in two circumstances.

One is when the physician prescribes the dosage to be administered to the patient taking into account the nature and severity of the disease.  The second one is from the standard specification that comes from the manufacturer of the drugs.
