FAQ
Frequently Asked Questions
How do I convert between area units?
1 square meter = 10,000 square centimeters. 1 hectare = 10,000 square meters. 1 acre = 4,047 square meters. 1 square kilometer = 100 hectares = 1,000,000 square meters.
How big is a hectare in everyday terms?
One hectare is 10,000 square meters, roughly the size of a standard soccer field (which is about 7,140 square meters). Two hectares approximately equal one city block.
Which values does the converter use for the Morgen and the acre?
Metric units and the acre are converted exactly (1 acre = 4,046.8564224 m²). For the Morgen, a traditional German land measure, the converter uses a flat 2,500 m², exactly a quarter of a hectare; historically the Morgen varied by region, and the Prussian Morgen measured about 2,553 m². In the converter, 1 hectare therefore equals 4 Morgen, and 1 Morgen equals 0.617763 acres. If an area in Morgen comes from an old land register entry or purchase contract, check which measure it refers to.

Key Data and Facts
1 ha = 10,000 m squared. 1 are = 100 m squared. 1 acre = 4,047 m squared. 1 square mile = 2.59 km squared. Football pitch: approx. 7,140 m squared.
Step-by-Step Guide
How to use the area converter step by step: 1. Choose the source unit – square metre (m2), square kilometre (km2), hectare (ha), are (a), square foot (sq ft), acre or square mile (sq mi). 2. Enter the value – the calculator converts it into all units. 3. Metric relationships: 1 ha = 10,000 m2, 1 a = 100 m2, 1 km2 = 100 ha. 4. Anglo-American units: 1 acre = 4,046.86 m2, 1 square mile = 2.59 km2. 5. Common applications: comparing plot sizes (e.g. 800 m2 = 0.08 ha = 8 a), converting living space from sq ft to m2 (1,000 sq ft = 92.9 m2), specifying agricultural areas in hectares. 6. Illustrative comparisons: a football pitch is about 7,140 m2 (0.71 ha), a tennis court about 261 m2. Tip: for plots of land in Germany, the are (100 m2) is a common unit in older land register entries.
Calculation Example
5,000 m2 in hectares: 5,000 / 10,000 = 0.5 ha. 2 acres in m2: 2 * 4,046.86 = 8,093.72 m2.
