Enter the total number of units and the land area in acres into the calculator to determine the number of units per acre.

Units Per Acre Formula

The following formula is used to calculate the number of units per acre.

UPA = TU / LA

Variables:

  • UPA is the units per acre
  • TU is the total number of units
  • LA is the land area in acres

To calculate the units per acre, divide the total number of units by the land area in acres.

What is Units Per Acre?

Units per acre is a measure of density commonly used in urban planning and real estate to describe the number of residential units or housing structures on one acre of land. This metric helps in understanding the level of development and is crucial for zoning regulations, development planning, and assessing the potential for real estate projects.

How to Calculate Units Per Acre?

The following steps outline how to calculate the Units Per Acre.


  1. First, determine the total number of units (TU).
  2. Next, determine the land area in acres (LA).
  3. Next, gather the formula from above = UPA = TU / LA.
  4. Finally, calculate the Units Per Acre (UPA).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.
