One square meter is about 10.76 ft². So if you know a room’s area in meters, multiplying by 10.76 gives a quick estimate in square feet.
Frequently asked questions
How do I calculate square footage?
Multiply length by width in feet to get the area in square feet: a 10 ft × 12 ft room is 120 ft². For several identical rooms, multiply by the quantity.
How do I convert square feet to square meters?
Multiply by 0.09290304, since one foot is 0.3048 meters and 0.3048² = 0.09290304. So 120 ft² equals about 11.15 m². To go from m² to ft², divide by the same factor.
Can I use meters instead of feet?
Yes — switch the unit to meters and the length and width are read in meters, giving the area in m². The calculator also shows the equivalent in ft².
