Why Use the Metric System...

Perhaps a better question is Why not use the metric system? 

For starters, the metric system is used by almost the entire planet. Indeed, the only countries that don't use metric are USA, Liberia and Myanmar... 

But more than just making sense so as to better participate with the great majority of humanity, there is a reason why almost all countries use the metric system: IT'S BETTER.

How is it better? 

• Easier math / conversions

• Simpler, easier to remember (conversions, etc.)

• More uniform naming structure

• Easier to teach

• It defaults to decimals rather than fractions

• It's the language of Science (even in the USA)

And all of that means that users of the metric system are far less likely to make errors in their conversions, calculations and measurements.

As an example (you try converting adding 3 1/2 pounds to 32 ounces - quick):

So why don't we (in the USA) use the metric system?... Don't get me started. 

But in cartography class - we will use the metric system. For those of us who grew up using the Imperial system, think of this as a small step toward learning the language of the rest of the planet.
