I have 5 acres and I'm selling to a European buyer. How do I explain the size?

5 acres = 2.02 hectares. Frame it as 'about 2 hectares'—Europeans will understand this as a small to medium property. Good for a house with land.

How much is 640 acres (one square mile)?

640 acres = 259 hectares. This is a large parcel used in US land surveys and represents substantial commercial or agricultural property.

How do I estimate acres to hectares mentally?

Rough estimate: divide by 2.5. Example: 5 acres ÷ 2.5 = 2 hectares. For precision, divide by 2.47105.

I'm comparing two farms — one in Kansas listed at 320 acres, one in France at 130 hectares. Which is larger?

320 acres = 129.5 hectares, so they're almost identical in size. The French farm at 130 hectares is just barely larger. Converting to a common unit like this is the only reliable way to compare land across countries.
