### Converting Metric Units of Measurement

The metric system is a comprehensive system of measurements used all over the world today. One of the biggest advantages that the metric system offers is that conversion between its units is simple and logical, as its units scale by powers of 10. Because of this, converting within metric measurements is usually as easy as multiplying or dividing a given measurement by a power of 10 to find the new value, or, as a shortcut, simply moving its decimal point.

The basic metric units are meters (for length), grams (for mass or weight), and liters (for volume).
There are many metric-unit prefixes, but the usual ones required in school are these: kilo-, hecto-, deka-, deci-, centi-, and milli-.

We are calculating metric conversions using the same basic conversion rule we used for the Customary System. Homework this week will have kiddos converting with both the Metric and Customary Systems. Please let me know if you have any questions!
