Instant, two-way conversion across common engineering units.
1 cm² = 1 × 10⁻⁸ ha(Square centimetre → Hectare)
To convert square centimeters to hectares, multiply the value by 1 × 10⁻⁸. Area figures drive floor space schedules, finish quantities and cost per area, so both metric and imperial results are shown at full precision.
The square centimeter (cm²) is the area of a square with 1 cm sides.
The hectare (ha) equals 10,000 square meters and is the standard metric unit for land area.
1 cm² equals 1 × 10⁻⁸ ha.
Multiply the value by 1 × 10⁻⁸. For example, 10 cm² equals 1 × 10⁻⁷ ha.
1 ha equals 100,000,000 cm². The converter above works in both directions, so you can type into either field.
Hectares are the metric standard for site and land areas in most planning systems, while acres remain common in US and UK land records. Use whichever the local authority requires and quote the other in brackets.
Square the length factor. Because 1 ft = 0.3048 m, one square foot is 0.3048², which is 0.09290304 m².
