This template displays area density measurement units used within various Category:Geobox templates, automatically converting between metric/imperial values. The input must be unformatted numeric values (i.e. without commas, the commas are automatically added to the output).

It can display and convert following units:

  • /m2 to /sq ft (/square metre to /square foot) and vice-versa
  • /ha to /acre (/hectare to /acre) and vice-versa
  • /km2 to /sq mi (/square kilometre to /square mile) and vice-versa

The template has 3 unnamed parameters: {{Unit area| unit| value| round}}. Their meaning is as follows:

  1. unit … obligatory, unit (sqm/m, sqft/ft, ha, acre, sqkm/km, sqmi/mi) of the value parameter, it will get displayed first
  2. value … obligatory, numerical value
  3. round … mandatory, number of decimal digits (negative numbers can be used for rounded figures); if not specified 0 is assumed
  • {{Unit area density|sqkm|1000}}: 1,000 / km2 (2,590 / sq mi)
  • {{Unit area density|sqmi|1000}}: 1,000 / sq mi (386 / km2)
  • {{Unit area density|sqkm|1000|-2}}: 1,000 / km2 (2,600 / sq mi)
  • {{Unit area density|sqft|1000}}: 1,000 / sq ft (10,763.91 / m2)
