While area calculation and conversion may sound easy at the surface level, it can easily become tedious and errorprone! In the following article, we shall briefly go over how to calculate lot size in acres and conversion rates between acres and other area units.
Calculating lot size in acres
In most cases, calculating lot size is as straightforward as calculating the area of the rectangular plot of land using the rectangle area formula:
where:

$\rm Area$ Area of the rectangular lot;

$\rm length$  Length of the lot; and

$\rm width$  Width of the lot.
🔎 Occasionally, a plot may not be rectangular. In such cases, try to divide the plot into shapes that resemble regular geometry, such as rectangles, triangles, etc. Then, you can calculate the area of individual parts and sum them up to find the total lot area!
Next, you must convert your area into acres. To do this, you need to know the various conversion rates summarized in the table below:
Area unit  acre (ac) conversion rate 

Square meters (m^{2})  1 m^{2} = 0.0002471054 ac 
Square kilometers (km^{2})  1 km^{2} = 247.1054 ac 
Square feet (ft^{2})  1 ft^{2} = 0.00002295684 ac 
Square yard (yd^{2})  1 yd^{2} = 0.0002066116 ac 
Square miles (mi^{2})  1 mi^{2} = 640 ac 
ares (a)  1 a = 0.02471054 ac 
decares (da)  1 da = 0.2471054 ac 
hectares (da)  1 ha = 2.471054 ac 
1 soccer field (sf)  1 sf = 1.764333 ac
