SI - Units of Measure

The Metric System makes use of a standardized set of Standard International Units (SI) to measure physical properties such as length, area, volume, and time. This system will allow you to begin creating a map of the Natural World using mathematics as your language.

Here is a table of standard units that scientists use to describe the Natural World throughout the physical sciences:

Standard Units (primary units):
Magnitude Unit Abbrev.
length (distance) meter m.
time second s.
mass gram g.
volume liter l.
byte storage b.
temperature Kelvin K.

These units form the basis for mapping out the Natural World in a predictable, consistent manner. While each of these units can be used by themselves, they are often  combined with one another to measure other aspects of Nature.

Combining Units I:
Magnitude Units Abbrev.
speed (distance/time) meters/second m/s
velocity (distance/time) meters/second m/s

Compound units (my language) can even be further combined to develop additional ways to describe phenomena found in Nature.

Combining Units II:
Magnitude Units Abbrev.
acceleration (velocity/time) (meters/second)/second m/s2

Even before you learn formal definitions for speed, velocity, and acceleration, the units will provide clues to the physical properties that you are measuring. The metric system uses a standard set of prefixes to make it easier to measure magnitudes that are either very large or very small.
