Frequently Asked Questions

Why are there so many different systems of measurement (apothecary, metric, and household)?

The apothecary system is from ancient times and is seldom used. The metric system is the easiest system to use, because it is based on units of 10 and is used in all of Europe. The household system is used in the United States. It is not based on any common unit or nomenclature, so it is more difficult to learn, and errors are more common. The United States government attempted to convert all Americans to the metric system, but the plan failed due to resistance and the high costs of conversion.

Why do I have so much trouble with math? *

Many people have difficulty with math. Some of the reasons:

* The extensive use of calculators and computers has decreased the practice required to learn the skill thoroughly.

* There are many myths and mind games that people believe, and these can inhibit one’s ability to master math.

* Accuracy is required or an error can lead to harm, which places greater psychological stress on the process.

Why do I have to learn two methods of recording time (the 12-hour and the 24-hour clock) and two temperature scales (Fahrenheit and Celsius)?

Both systems of time and temperature scales are used in many health care facilities. Lack of knowledge of both methods would inhibit your employability and ability to function well within the health care system.
