We study simple conversions between metric measuring units that are based on the conceptual understanding of decimals. For example, since we know that 0.001 (one-thousandth) of a meter is a millimeter, then 5 millimeters means 5 thousandths of a meter, and as a decimal is written 0.005 m.
Another example. The prefix "centi" basically means one hundredth. So, 6 centiliters literally means 6 hundredths of a liter, or 0.06 L.
So, this understanding of decimal place value gives us an easy means of converting quantities expressed in derived units back to the basic unit (such as meter, liter, or gram).
