The metric system is all based on 10, so conversions are easy. By sliding the decimal point to the left or right, we can easily convert from one unit to another. This system works for length (METERS), volume (LITERS) and mass (GRAMS).
To move from one measurement to another, you just move the decimal point to the left or to the right. In our table above, instead, from top to bottom or bottom to top.
