The Metric System:

The top row is an easy mnemonic
to remember the order of the prefixes (bottom row) to the metric system.  The first letters of the words stand for the respective prefixes of the units in the metric system. The word {usually} in the middle leaves a place for the unit (meter, liter, or gram.)  The Metric System is a base 10 system.

It is easy to convert between the units in the metric system. First locate the decimal in the number and then move the decimal in the same number of place values and in the same direction as the new unit.

 Convert 3.62 kg to gram 3.62 kg = 3620. g gram is 3 powers of 10 to the right of kilogram, move the decimal 3 place values to the right (a zero must be annexed) Convert 2.55 cm to meter 2.55 cm = .0255 m meter is 2 powers of 10 to the left of centimeter, move the decimal 2 place values to the left (a zero must be annexed) Convert 752 ml to kiloliter 752.ml = .000752 kl kiloliter is 6 powers of 10 to the left of milliliter, move the decimal 6 place values to the left (3 zeroes must be annexed) Convert 69.78 g to cg 69.78 g = 6978. cg centigram is 2 units to the right of gram, move the decimal 2 place values to the right
