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.

 from \ to = __ acres = __ feet2 = __ inches2 = __ meters2 = __ miles2 = __ yards2 acre 43560 6272640 4046.856... (1/640) 4840 foot2 (1/43560) 144 0.09290304 (1/27878400) (1/9) inch2 (1/6272640) (1/144) 6.4516E - 4 3.587006E - 10 (1/1296) meter2 2.471054...E - 4 10.76391... 1550.0031 3.861021...E - 7 1.195990... mile2 640 27878400 2.78784E + 9 2.589988...E + 6 3097600 yard2 (1/4840) 9 1296 0.83612736 3.228305...E - 7

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
