Convert cm² or width and length in centimeters to square feet, or reverse square feet to cm², with square-meter, square-inch, and square-yard equivalents.
Assumptions Assumptions
- Direct conversion is area-to-area; the width × length mode assumes a rectangle. Measurement tolerances are not included.
- All unit factors are exact or standard: 1 ft = 0.3048 m (exact); 1 ft² = 0.09290304 m²; 1 cm² = 1e-4 m²; 1 in² = 0.00064516 m²; 1 yd² = 0.83612736 m²; 1 acre = 4046.8564224 m²; 1 hectare = 10000 m².
- Output is rounded for display; internal math uses double precision.
- US and Imperial feet are identical (0.3048 m), so no separate setting is required.
When to Use This Calculator
- Converting floor, wall, or ceiling coverage between metric and US customary plans.
- Estimating paint, tile, carpet, turf, or roofing materials from cm²/ft² specs.
- Standardizing area measurements for real estate, architecture, or engineering notes.
Input Definitions
- Square centimetres — enter area in cm², or choose the rectangle mode and enter both width and length in cm.
- Square feet — enter an area in ft² for reverse conversion to cm².
- Conversions — ft² = cm² ÷ 929.0304; cm² = ft² × 929.0304; equivalently ft² = cm² × 0.001076391041671.

cm to sq ft Formula
The following formulas convert between square centimeters and square feet using the exact relationship 1 ft² = 929.0304 cm².
ft² = (cm²) / (929.0304)
cm² = 929.0304 ft²
- 1 ft = 0.3048 m (exact)
- 1 ft² = 0.09290304 m² = 929.0304 cm²
- 1 cm = 0.01 m; 1 cm² = 1e-4 m²
- 1 in² = 0.00064516 m²; 1 yd² = 0.83612736 m²
How do you convert cm² to ft²? Divide the area in cm² by 929.0304 (or multiply by 0.001076391).
How do you convert ft² to cm²? Multiply the area in ft² by 929.0304.

Example Problem
Convert 2,500 cm² to square feet.
Use the formula: ft² = cm² ÷ 929.0304.
ft² = 2,500 ÷ 929.0304 ≈ 2.690978 ft²
