How many hectares are there in one acre?

• A. 0.2 hectares
• B. 0.4 hectares
• C. 1 hectare
• D. 0.75 hectares

Answer: (B)

To understand why the correct answer is 0.4 hectares, it's essential to know the conversion between acres and hectares. One acre is a unit of area commonly used in the United States and other countries, while a hectare is predominantly used in the metric system. The conversion factor is crucial: 1 acre is equal to approximately 0.404686 hectares. This value means that when you convert one acre to hectares, you are looking at just over 0.4 hectares. Thus, rounding this value to one decimal place gives us about 0.4 hectares, making it the most accurate choice for this conversion. Understanding this relationship is important for problems involving land measurement, particularly when switching between different systems of measurement. This knowledge not only helps in solving this specific question but also applies to real-world scenarios such as real estate and agriculture.
