Systems of Measurement: there are two main systems of measurement in the world: the Metric (or decimal) system and the US standard system.  In each system, there are different units for measuring things like volume and mass.

What makes the US standard systems different from the Metric system?

  • The Metric (or Decimal) system is made of units based on powers of 10.  To convert units, all you need to do is move the decimal point.  The prefix (beginning part of the word- i.e. kilo or milli) describes the size of the given unit.  For example, kilogram means 1000 (kilo) grams. 
  • The US Standard system uses units that have no predictable relationship to each other.  For example, there are 2 cups in a pint, but 4 quarts in a gallon.  There are 16 ounces in a pound, but 2000 pounds in a ton.  To convert units, you divide or multiple according to the relationship between the two given units.
