eaming Goal: o convert between metric units expressing length, area, and volume. Converting squared units When converting areas, you must be careful to properly square the units to produce the correct ratio. Think of mm? as (mm) = (mm) - (mm). That is to say, think of this as a pair of millimeter units, each of which must be converted separately. To convert 130 mm² to square meters, you would use the following calculation: he ability to convert from one system of units to another is important in hemistry. It is often impractical to measure quantities in the standard reters, kilograms, and seconds, but the laws of science that you learn will volve constants that are defined in these units. Therefore, you may often ave to convert your measured quantities into different metric units. he following table lists metric prefixes that come up frequently in hemistry.

Leaming Goal: To convert between metric units expressing length, area, and volume. Converting squared units When converting areas, you must be careful to properly square the units to produce the correct ratio. Think of mm? as (mm)? = (mm) - (mm). That is to say, think of this as a pair of millimeter units, each of which must be converted separately. To convert 130 mm? to square meters, you would use the following calculation: The ability to convert from one system of units to another is important in chemistry. It is often impractical to measure quantities in the standard meters, kilograms, and seconds, but the laws of science that you learn will involve constants that are defined in these units. Therefore, you may often have to convert your measured quantities into different metric units. The following table lists metric prefixes that come up frequently in chemistry.
