The medication dose calculator provides warnings when the inputted amount of drug exceeds the dosage range limits or is incorrect. The medication dose calculator converts an inputted drug unit of measure into a desired unit of measure. In addition, various methods for receiving, recording, storing, transmitting, transferring, and editing information along with various processes utilizing the medication dose calculator are disclosed.
