They are: Meters (m) measurement of distance Liters (L) measurement of volume Grams (g) measurement of mass or weight The metric system uses prefixes to denote powers of ten followed by the unit of measurement (m, L, or g). These are the most common prefixes used in chemistry: Mega (M) = million Kilo (k) = thousand Hecto (h) = hundred Deka (da) = ten Deci (d) = tenth Centi (c) = hundredth Milli (m) = thousandth Micro ( ) = millionth For example: A centimeter ha s the prefix “centi” that tells us that the power of ten is 10 -2 (hundredth) followed by “meter”, which is the unit for measuring distance in the metric system. This means that a centimeter is one-hundredth of a meter. Conversions within the metric system can be confusing at first. The diagram below is a number line with the prefixes shown and the base unit (m,
