Units of Measurement

The unit m³ is used to express

• length

• mass

• volume

• density

SI base units for length and mass are

• centimeter

• meter and gram

• centimeter and kilogram

• meter and kilogram

The abbreviations for units of length in order from smallest to largest are

• m, cm, mm, km

The conversion factor  $\frac{1000\ mL}{1\ L}$  would be used to change

• mass to density. 
  

• liters to milliliters. 

• units of volume to units of length.

• units of length to units of volume
