They tried to convert us to the Metric system when I was in school in the 90's and I never could catch on.No one could.The school district ended up
dropping the idea.I struggle with the metric system because we use it a lot in the Military and i'm usually like " WHAT?" I'll stick with what I
know.Thanks.
Well here's a quick lesson that only takes about 5 minutes. The metric system isn't that hard at all, and everyone should at least give it a try.
I assume when you say you use it in the military that you use the kilometer, correct? Well, a kilometer is 1,000 meters because of the prefix
"kilo." There are 5 other prefixes as well, which are just multipliers; such as kilo. Kilo is "times 1,000." So 1 kilometer is 1,000 meters. There
are 6 total prefixes: kilo, hecto, deca, deci, centi, and milli. This is an advantage because if you need a larger unit you just shift the decimal
point, instead of multiplying or dividing with the English system. (Instead of multiplying "miles" times 5,280 to find how many feet are in a
certain number of miles, all you'd have to do to find meters in a kilometer is shift the decimal point. No math required.)
For example, if you have a distance of 4 kilometers...
4 kilometers are:
40 hectometers are:
400 decameters are:
4,000 meters are:
40,000 decimeters are:
400,000 centimeters are:
4,000,000 millimeters:
That's all there is to it. If you need a larger unit you shift the decimal place over and tack on a multiplier word. It gets even easier, though.
Even in science they don't use the "hecto," "deca," and "deci" prefix, so there's no need to worry about those. They're just there if you
need them for something.
I hope this makes it a little clearer. No, it's difficult to use a unit if you don't know a lot about how the system works. (I felt the same way
before I found out the meaning behind the prefixes.)
But if you're just having trouble finding reference points, think of it this way: a kilometer is about 10 football fields long and an hour's drive
is about 80 kilometers. Once you have reference points it becomes just as easy as miles.
