Unit Converter
Convert between 100+ units across 11 categories — length, weight, temperature, area, volume, speed, time, digital storage, energy, pressure, and angle. Instant results with formula explanations and full conversion tables.
Convert area between square millimetres, square centimetres, square metres, square kilometres, square inches, square feet, square yards, acres, and hectares. Instant results with conversion factor, base-unit explanation, and a full reference table.
Use this free area converter to switch between square metres, square feet, acres, hectares, square inches, and more. It is useful for property listings, room measurements, landscaping plans, flooring estimates, classroom work, and design specifications. The tool also connects naturally to the Unit Converter, Length Converter, and the wider Conversion Tools category.
Pick your input and output units, enter an area value, and get instant conversions with a full reference table.
Use the presets below for common square-unit scenarios, from room layout planning to property-size comparisons.
Compare your result against every supported unit. Filter by measurement family to focus on metric, imperial, or land-area outputs.

|---|---|---|
Square Millimetres mm² | Metric | 35,000,000 mm² |
Square Centimetres cm² | Metric | 350,000 cm² |
Square Metres m² | Metric | 35 m² |
Square Kilometres km² | Metric | 0.000035 km² |
Square Inches in² | Imperial | 54,250.1085 in² |
Square Feet ft² | Imperial | 376.7368646 ft² |
Square Yards yd² | Imperial | 41.85965162 yd² |
Acres ac | Land and property | 0.008648688351 ac |
Hectares ha | Land and property | 0.0035 ha |
Enter the numeric area value you want to convert, choose the original unit, and then pick the destination unit. The result updates instantly, so you can compare room sizes, land plots, printed surfaces, or material coverage without having to remember area formulas manually.
Because area uses squared units, the conversion factors can be much larger or smaller than plain length conversions. That is why this dedicated tool is useful alongside the Length Converter and the broader Unit Converter when you need a focused property or surface-area workflow.
For construction and property work, square metres, square feet, acres, and hectares are the most common units to compare. For packaging, design, and manufacturing, square centimetres and square inches are often more practical. This page keeps those conversions in one fast reference view.
Area Converter is part of the Conversion Tools collection. If you want a broader view of similar workflows, open the Conversion Tools category page or browse all QuickTools categories.
