  • {{convert|85|/km2|abbr=on}} → 85/km2 (220/sq mi)
  • {{convert|220|/sqmi|abbr=on}} → 220/sq mi (85/km2)

The code uses {{precision}} to determine the level of precision. The logic is to give preference to km2/sqmi over m2/sqft. If both km2 and sqmi are specified, then no conversion takes place. Similarly, if both m2 and sqft are specified (and km2/sqmi are not specified), then no conversion takes place.
