How to Convert Lot Size to Acres
Converting a property's lot size to acres is a common task in real estate, land management, and farming. An acre is a unit of land area used in the imperial and US customary systems. Understanding this conversion is essential for accurately describing and comparing land parcels.
The Magic Number: 43,560
The most important number to remember when dealing with acres is:
1 Acre = 43,560 Square Feet
This is the fundamental relationship used for most conversions. An acre can be any shape, but it will always contain 43,560 square feet.
Converting Square Feet to Acres
To convert a lot size given in square feet to acres, you simply divide the square footage by 43,560.
Acres = Total Square Feet / 43,560
Example: A common suburban lot might be 10,000 square feet.
10,000 sq ft / 43,560 = 0.2295 acres
So, a 10,000 sq ft lot is just under a quarter of an acre.
Converting from Other Units
If your lot size is in a different unit, you first need to convert it to square feet, then convert to acres.
- Square Meters (sq m): 1 square meter ≈ 10.764 square feet.
- Hectares (ha): 1 hectare = 10,000 square meters ≈ 107,639 square feet. (A hectare is also roughly 2.471 acres).
Example (from Square Meters): A lot is 5,000 square meters.
Step 1: 5,000 sq m × 10.764 = 53,820 sq ft
Step 2: 53,820 sq ft / 43,560 = 1.235 acres
