How to Calculate Square Feet Manually
If you want to calculate manually:
Formula
Square Feet = Length (in feet) × Width (in feet)
Example 1: Room Area
Length = 12 ft
Width = 10 ft
Area = 12 × 10 = 120 sq ft
Example 2: Plot Area
Length = 40 ft
Width = 25 ft
Area = 40 × 25 = 1000 sq ft
Square Feet Calculation for Other Units
Feet to Square Feet

Inches to Square Feet
1 ft = 12 inches
Convert inches → feet → apply formula.
Meters to Square Feet
1 square meter = 10.7639 square feet
