Quick measurement converters

Fabric area converter

Convert square centimetres, square metres, square inches, square feet and square yards.

Use a single decimal point or comma, without thousands separators or unit symbols. All lengths use the selected unit. Values must be 0–1,000,000; dimensions and swatch counts must exceed zero. Counts must be whole numbers. Extra allowance: 0–100%; lengthwise shrinkage: 0–50%.

Assumptions & limits

Area factors are the squares of international length factors. A square yard is not a linear yard of a roll. Converting area does not solve cutting layout, fabric width, grain direction, seam allowance or waste.

Formula

output = input × (source length factor ÷ target length factor)²

Worked example

1 yd² = 0.83612736 m²; 1 in² = 6.4516 cm².

Results show up to 8 decimal places. Small values use scientific notation; calculations use unrounded factors.
