How to Calculate Square Meters Into Square Feet

Square meter is the unit of area determined by the International System of Units (SI). However, a square foot as a unit of area is widely used in United State and some other countries such as Canada or United Kingdom. Effective July 1, 1959, U.S. National Bureau of Standards defined that 1 foot is 1200/3937 meter. It allows to obtain the formula to convert square meters into feet.

Things You'll Need

• Calculator

Instructions

1. Calculate the conversion co-efficient between foot and meter in the decimal form.
   1 foot = 1200/3937 meter = 0.3048 meter.

2. Obtain the formula to convert meters to feet using the coefficient from Step 1.
   Feet= meters/ 0.3048.

3. Obtain the formula to convert Square meters to Square feet
   Square feet=Square meters/ (0.3048x0.3048)= Square meters/0.09290304= 10.7639 x Square meters.
   In our example,
   Area=10.7639 x 12 square meters =129.17 square feet.
