How to convert acres to square feet?

Acre to square feet conversion is much easier than you think! All you need is a conversion factor equal to approximately: 43560 ft²/ acre.

Let's try it out with a simple example:

Our field has an acreage of 500 ac. We'd like to translate acre to sq feet (ft²).

Area in ft² = Area in ac * 43560

Area in ft² = 500 * 43560

Area in ft² = 21780000

Now we know - our field has 21780000 square feet.

How many square feet are in an acre?

One acre contains approximately 43560 square feet [ft²].

(To be precise, it's exactly 43559.99545 ft².)

How much acreage is equal to 100 square feet?

Let's calculate it step by step. 🧮

We already know that the acre to square feet conversion factor equals 43560 ft²/ acre. But what should we do if the conversion we're looking for goes the other way around? Let's try the following formula:

Area in acres = Area in ft²/ 43560

Area in acres = 100 ft²/ 43560

Area in acres = 0.002295684


How to convert 1 acre to sq ft?

Let's turn 1 acre to sq ft using one simple step:

  1. Multiply your acres by the conversion factor: 43560 ft²/ acre
