What Math Do You Need to Know to Become a Pharmacist Tech?

Growth Trends for Related Jobs

You don't need years of medical school to work as a pharmacy technician, but you do need to know a bit of math. On the job, you'll use math concepts such as percentages, algebra, ratios and fractions to measure out medication, fill prescriptions and keep tabs on the pharmacy's inventory. It's important for you to understand math concepts in several measurement systems so customers get the correct amount of medication needed.

Measurement Systems and Conversions

As a pharmacy technician, you'll spend much of your time on the job measuring medications. You will need a firm grasp on several measurement systems -- especially the metric, avoirdupois and apothecary systems. The apothecary system is used for measuring some thyroid drugs and aspirin. The avoirdupois system is commonly used for prepackaged or bulk medications. Drug doses are typically given in milligrams, grams or milliliters, so you'll use the metric system most often. You'll also need to know how to convert prescriptions between measurement systems. Pharmacy computer systems use metric measurements for medication doses, for example, but prescriptions are often given to customers in ounces, teaspoons or drops.

Algebra and Accounting

To perform measurement conversions, some basic algebra is required. For example, you'll need to multiply numbers to get a bigger measurement or divide numbers to find a smaller measurement. You will also be working with fractions and percentages. Pharmacy technicians should have some knowledge of accounting, including concepts of inventory management, accounts payable and accounts receivable. You'll take payment from customers for medications, and you may need to relay payment information to the customer's insurance company.
