Frequently asked questions
Why is one square metre so much more than one square foot?
The conversion factor is squared because area scales with length twice, so one square metre equals 10.7639 square feet, not 3.28. The tool applies the exact 0.09290304 factor when going feet to metres and its reciprocal back, and also reports acres by dividing by 4,046.86. Converting 1,000 sq ft therefore yields about 92.9 m squared, a number that surprises anyone who only converts linear feet to metres in their head.
