Area conversions are useful for room measurements, flooring estimates, roof takeoffs, drywall coverage, paint coverage, tile projects, land parcels, slabs, patios, and construction planning.
Use this converter when comparing imperial, metric, roofing, and land area units.
Your result shows the entered area converted from the starting unit into the selected ending unit. The converter also shows the conversion rate used so you can verify the calculation.
For material estimates, remember that this converter only changes units. Flooring, roofing, drywall, and paint projects may still need waste, overlap, cuts, or product-specific coverage added separately.
