## Chemistry: Molecular Approach (4th Edition)

Prefix multipliers are used to change the value of a unit by powers of 10. For example, $1 milliliter = 1 mL = 10^{-3} Liters$
Along with the base units, prefix multipliers are used in SI system of units. Prefix multipliers change the unit value by powers of 10. Prefix multipliers are used to express a large number of measurements in the units that are similar in size to that quantity which we are measuring. For example: $1 kilogram = 1 kg = 10^{3} grams$ $1 megabyte = 1 MB = 10^{6} bytes$ $1 millimeter = 1 mm = 10^{-3} meters$
