A hectare (symbol: ha) is a metric unit of area equal to 10,000 square meters (100 m x 100 m). Introduced alongside the metric system in 1795 during the French Revolution, the hectare is now the standard unit for reporting land area in agriculture, forestry, and urban planning across most of the world. The prefix "hecto" means one hundred, and an "are" is 100 square meters, so a hectare is literally "one hundred ares." It is the primary unit used in land registries, environmental reporting, and scientific research internationally.
An acre is a unit of land area used primarily in the United States, United Kingdom, and other countries with historical ties to the imperial measurement system. The word comes from the Old English acer, meaning "open field." In medieval England, an acre was defined as the amount of land a yoke of oxen could plow in one day. Today, one acre is precisely defined as 43,560 square feet (4,046.8564224 square meters). An acre can be any shape -- it is purely a measure of total area, not dimensions.
The relationship between these units is: 1 hectare = 2.47105 acres, or inversely, 1 acre = 0.404686 hectares. Converting hectares to acres is essential when interpreting international property listings for US or UK buyers, translating agricultural data between metric and imperial systems, and working with cross-border land surveys.
The formula to convert hectares to acres is: Acres = Hectares x 2.47105. Simply multiply the number of hectares by the conversion factor 2.47105 to get the equivalent area in acres.
Question: A property in France is listed at 0.5 hectares. How many acres is that for a US buyer?
Question: An international crop yield report lists a field as 25 hectares. How many acres is that?
Note: This is roughly the size of a mid-size American family farm.
Question: A nature reserve covers 500 hectares. How many acres is that?
For a quick estimate, multiply hectares by 2.5 (slightly more than the exact factor of 2.47105). This gives you a result within 1.2% accuracy. For example: 100 hectares x 2.5 = 250 acres (exact: 247.1). Another trick: double the hectares, then add another quarter. So 40 ha x 2 = 80, plus 10 = 90, plus 10 more = 100 acres (exact: 98.8). Both shortcuts work well for quick back-of-envelope calculations.

Property listings in most countries use hectares, but US and UK buyers think in acres. When browsing land for sale in Europe, Latin America, or Asia, converting hectares to acres lets buyers quickly gauge plot sizes against their frame of reference and compare prices per acre.
Global commodity markets, the UN Food and Agriculture Organization, and international crop reports all use hectares. American farmers and agricultural businesses converting these figures to acres can better compare yields, input costs, and pricing with their own operations.
Deforestation rates, carbon offset projects, and national park areas are reported in hectares worldwide. Conservation professionals and policy makers in the US need to convert to acres to communicate findings domestically and compare with local protected areas.
People relocating from metric countries to the US or UK often encounter acres for the first time in housing listings. Converting familiar hectare sizes to acres helps newcomers understand neighborhood lot sizes, zoning requirements, and how much land they are actually purchasing.
Three decimal places (2.471) gives accuracy within 0.002% -- more than sufficient for most real estate and agricultural purposes.
If you convert 10 hectares and get 2.47 acres, you divided instead of multiplied. The acre number should always be larger than the hectare number.
Hectares to acres requires multiplication by 2.47105. Dividing by 2.47105 converts acres to hectares -- the wrong direction.
A property listed as "2 hectares" is about 5 acres, not 2. Misreading hectares as acres underestimates the land by 60%.
This common approximation underestimates by 19%. The correct quick estimate is 2.5 acres per hectare, not 2.
One hectare equals exactly 2.47105 acres. This means a hectare is roughly two and a half times the size of an acre. To convert any number of hectares to acres, multiply by 2.47105. For example, 10 hectares equals 24.7105 acres.
A hectare is larger than an acre. One hectare equals approximately 2.471 acres. A hectare is 10,000 square meters (100m x 100m), while an acre is only 4,046.86 square meters. So a hectare is about 2.5 times the size of an acre.
Multiply the number of hectares by 2.47105. For example: 5 hectares x 2.47105 = 12.355 acres. For a quick mental estimate, multiply hectares by 2.5 (slightly higher than the exact factor but easy to calculate in your head).
One hectare equals exactly 10,000 square meters. A hectare is defined as a 100-meter by 100-meter square. It is equivalent to 2.47105 acres, 107,639 square feet, or 0.01 square kilometers.
One acre is about the size of a standard American football field without end zones (roughly 90% of the full field). It equals 43,560 square feet or 4,046.86 square meters. For a metric comparison, one acre is approximately 0.405 hectares.
You may need this conversion when buying property in the US or UK where acres are standard, reading international land listings while based in a metric country, comparing agricultural yields across measurement systems, or working with US land survey data that uses acres and sections.
An American football field (including end zones) is about 0.535 hectares or 1.32 acres. Without end zones, the playing field is approximately 0.445 hectares or 1.1 acres. A soccer (football) pitch varies but is typically around 0.71 hectares or 1.76 acres.
Yes. A hectare is defined as exactly 10,000 square meters, and an international acre is defined as exactly 4,046.8564224 square meters. Therefore one hectare equals exactly 10,000 / 4,046.8564224 = 2.4710538146717... acres. The commonly used factor 2.47105 is rounded to five decimal places, which is accurate enough for virtually all practical purposes.
This calculator uses the internationally recognized conversion factor of 1 hectare = 2.4710538146717 acres (derived from 1 acre = 4,046.8564224 m² and 1 hectare = 10,000 m²). For legal land descriptions, surveying, and official documents, always verify conversions with a licensed surveyor or refer to your jurisdiction's official measurement standards.
