# How Do Veterinarians Use Math in Their Jobs?

## Dosage

One of the main uses of math in the job of a veterinarian is figuring dosages. Medication dosages are determined by an animal's weight. For instance, the following indication may be on a medication: Administer 2 cc's (cubic centimeters) per 5 lbs. of body weight. Therefore, the veterinarian would have to perform the following equation in order to determine the correct dosage for a dog weighing 40 lbs.: 40/5 = 8; 8 x 2 = 16. The dog would receive 16 cc's of the medication.

## Conversions

Another part of dosages that involves math is conversions. A veterinarian must be able to convert between measurements if necessary. For instance, a medication may read as follows: Administer 5 cc's daily for each 10 lbs. of body weight. The veterinarian would know a 30-lb. dog would need 15 cc's of medication each day. However, the pet's owner may not have a device that measures in cubic centimeters. Therefore, the veterinarian must be able to convey to the owner that 5 cc's equal 1 tsp., and 15 cc's equal 1 tbsp. By using more common measurements, the veterinarian can instruct the pet owner to give 3 tsp. or 1 tbsp. of medication daily.
