Unit Conversion Tables for Areas

A note on the metric system:
Before you use this table convert to the base measurement first. For example, convert centimeters to meters, convert kilograms to grams.

The notation 1.23E - 4 stands for 1.23 x 10-4 = 0.000123.

To use: Find the unit to convert from in the left column, and multiply it by the expression under the unit to convert to.
Examples: foot2 = 144 inches2; 2 feet2 = 2x144 inches2.

 

Useful Exact Area & Length Relationships

 

acre = (1/640) miles2


mile = 1760 yards = 5280 feet


yard = 3 feet = 36 inches


foot = 12 inches


inch = 2.54 centimeters

Note that when converting area units:


  1 foot = 12 inches
  (1 foot)2 = (12 inches)2 (square both sides)


  1 foot2 = 144 inches2


The linear & area relationships are not the same!
