Military Flight Aptitude: Prefixes in the Metric System
Believe it or not, the military flight aptitude tests require you to have knowledge in a wide range of technical and scientific topics, so you need to cover down on those subjects (that’s a military term for getting a grasp of something) to ensure your exam success.
Go ahead and review all the scientific subject matters that you need to know to perform well on your test, including the fundamentals of biology, physics, anatomy, chemistry, and the earth sciences.
Your study and review won’t make you an expert scientist, but they should serve as a good review for most of the courses you may have already taken.
If you haven’t previously studied the subjects, find some texts to gain a basic understanding and identify your weaknesses, and then dig deeper into the material by using various other subject matter materials found in any library. Who knows? You may actually enjoy this review; it’s all really fun and interesting stuff.
The metric system uses prefixes to indicate how a particular quantity relates to its base unit. This table lists some of the more common metric prefixes:
|Prefix (Symbol)||Numeric Equivalent||Example|
|nano (n)||10–9||0.000000001 meters = 1 nanometer (nm)|
|micro (μ)||10–6||0.000001 meters = 1 micrometer (μm)|
|milli (m)||10–3||0.001 meter = 1 millimeter (mm)|
|centi (c)||10–2||0.01 meter = 1 centimeter (cm)|
|deci (d)||10–1||0.1 meter = 1 decimeter (dm)|
|kilo (k)||103||1,000 meters = 1 kilometer (km)|
|mega (M)||106||1 million meters = 1 megameter (Mm)|
|giga (G)||109||1 billion meters = 1 gigameter (Gm)|
