Thanks, Dear Concerned Parent There are some very nice features of the metric system. One is that it is based on 10 like our number system and another is the language. For distance the basic unit is a meter. If you extend your arm to the side and point your finger then a meter is approximately the distance from the tip of your nose to the tip of your finger. The basic volume unit is a liter, approximately a quart, and the basic unit of mass is a gram, approximately the weight of one m&m. For converting measurements there is a uniformity in language, whether you are measuring distance, volume or weight. - The prefix deci designates one tenth, like decimal.
- The prefix centi designates one hundreth, like a cent.
- The prefix milli designates one thousanth.
For measurements larger than the basic unit there ae similar prefixes. - The prefix deka designates 10.
- The prefix hecto designates 100.
- The prefix kilo designates 1000.
There is also an easy way to convert from volume measured in liters to volume measured in cubic length units. One cubic centimeter is one milliliter. A cubic centimeter is approximately the size of a sugar cube. There is a connection to the mass units here also as one cubic centimeter of water weighs approximately one gram.
I hope this helps,
