Acres to Hectare Converter
Easily convert between acres and hectares (ha). Hectare is the primary metric land unit used worldwide, where 1 Hectare is equivalent to approximately 2.47 Acres.
1 Acres = 0.4047 Hectares
How to Convert Acres to Hectares
Converting acres to hectares relies on a constant factor derived from the relationship of metric square meters to square feet.
Since 1 acre is equal to 0.40468564 hectares, you simply multiply your acre value by 0.4047 to get the hectare value. Conversely, if you want to convert hectares back into acres, you multiply the hectare value by 2.471.
Acres to Hectare Formula
Acres to Hectares
Mathematical Formula:
Hectares = Acres × 0.4047
Example: 10 Acres × 0.4047 = 4.047 Hectares
Hectares to Acres
Mathematical Formula:
Acres = Hectares × 2.4711
Example: 5 Hectares × 2.4711 = 12.355 Acres

Understanding Acres vs Hectares
A comparison between imperial agricultural sizing and modern international metric units.
Global Standard Metric
While the United States and United Kingdom traditionally use Acres, the rest of the world (including the European Union, Canada, and Australia) has standardized land records on Hectares due to its clean relationship with the metric system.
The Hectare-to-Sq-Meter Link
One Hectare is exactly 10,000 square meters. It is equal to a square area of 100 meters by 100 meters, which makes mapping and engineering scaling straightforward.
Agricultural Sizing
Hectares are typically used for large-scale properties such as ranches, farms, public forests, and national parks, where measuring in square feet or meters results in overly large figures.
