Converting Acres to Square Meters and Feet

If you are buying land or reading real estate listings, you'll see "Acres" in the US/UK and "Hectares" or "Square Meters" elsewhere. How big is an acre really?

Quick Answer (TL;DR)

1 Acre equals:

• 43,560 Square Feet (Remember: "4-3-5-6-0")
• 4,047 Square Meters
• 0.405 Hectares

Visualizing an Acre:

• It is roughly 75% of an American Football Field (including endzones).
• It is a square roughly 208 feet × 208 feet.

The Hectare (The Metric Cousin)

In Europe, Australia, and Canada, land is sold in Hectares (ha).

• 1 Hectare = 10,000 Square Meters (100m × 100m square).
• 1 Hectare ≈ 2.47 Acres.

Quick conversion rule: A Hectare is approx 2.5 Acres.

Why 43,560 Square Feet?

Like the mile, it comes from the Furlong (660 ft) and the Chain (66 ft).

• An Acre was defined by one Furlong long (660 ft) by one Chain wide (66 ft).
• 660 × 66 = 43,560 sq ft.

It was the amount of land one man could plow in one day with an ox.
