Making Connections Glossary
unit of measure  
  A standard quantity (such as a centimeter, second, square foot, or gallon) that is used to measure and describe an object.  A single object may be measured using different units of measure.  For example, a pencil may be 80 mm long, meaning that the pencil is 80 times as long as a unit of 1 mm.  However, the same pencil is 8 cm long, so that the pencil is the same length as 8 cm laid end-to-end.  This is because 1 cm is the same length as 10 mm.
unit price  
  The cost of one item or one measure of an item.  For example, cost for one pound or one gallon.
unit rate  
  A rate with a denominator of one when simplified.
units digit  
  The numeral in the ones place.
