Unit Conversion Table for Area

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.

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
