Understanding the Concept
A hectare and an acre are two units of land area. A hectare is a metric unit equal to 10,000 square meters, while an acre is an imperial unit equal to 4,046.86 square meters. Therefore, one hectare is approximately 2.47 acres.

Conversion Factors
The following conversion factors can be used to convert between hectares and acres:
- 1 hectare = 2.47 acres
- 1 acre = 0.4047 hectares
Applications in Various Industries
Hectares and acres are commonly used in various industries, including:
