Practical Examples
1 dunam
equals
1,550,003.1 in²
5 dunam
equals
7,750,015.5 in²
10 dunam
equals
15,500,031 in²
25 dunam

Forwardin² = dunam × 1,550,003.1
Reversedunam = in² × 6.452e-7
Example: 10 dunam × 1,550,003.1 = 15,500,031 in²

Tips

Use these in everyday conversions
  • 1 dunam = 1000 m² = 0.1 ha.
  • 10 dunams = 1 hectare.
  • Historical Ottoman dunam was 919.3 m² — avoid if possible; modern is 1000.

Common Mistakes

Avoid these
  • Using Ottoman dunam figures in modern Turkish contracts — assume metric.
  • Confusing with other Middle Eastern units (feddan, etc.).
  • Assuming all regional dunams are identical — confirm modern 1000 m² value.

About Dunam and Square Inch

What is the Dunam?

The dunam equals exactly 1,000 square meters in its modern metric form, used primarily in Israel, Jordan, Lebanon, Palestine, Syria, and Turkey for land measurement and real estate. The unit's name derives from Ottoman Turkish 'dönüm,' itself from a verb meaning 'to turn' — historically the area a yoke of oxen could plow in a day, similar to the acre's origin. Older 'Ottoman dunam' values varied (around 919 m²), but most countries in the region have standardized to the metric dunam of 1,000 m². The dunam is the everyday unit in Middle Eastern real estate and agricultural contexts. It relates to the square meter (1 dunam = 1,000 m² = 0.1 ha), the hectare (10 dunams = 1 ha), and the acre (1 acre ≈ 4.047 dunams). Family olive groves, vineyards, and urban building plots are routinely measured in dunams.

  • Israeli and Palestinian land records
  • Turkish rural property
  • Agricultural documents in the former Ottoman region
Real-world examples

An Israeli small farm might be 50 dunams (5 ha). Agricultural yields sometimes quoted per dunam.

What is the Square Inch?

The square inch equals exactly 6.4516 square centimeters and is the American precision unit for printer paper coverage, manufacturing tolerances, and small-area calculations. Pressure in the US is measured in pounds per square inch (psi), so the unit is essential in engineering and tire-pressure ratings. Computer screens are sometimes specified by total viewable square inches. The square inch relates to the square foot (144 in² = 1 ft²), the square centimeter (1 in² = 6.4516 cm²), the square millimeter (1 in² ≈ 645.16 mm²), and the square meter (1 in² ≈ 0.000645 m²). Postage-stamp areas, electronic-circuit board details, and machined-part tolerances all use square inches in American engineering practice.

  • US machine engineering and drawings
  • Tile, flooring and surface specifications
  • Pressure units (PSI) base area
Real-world examples

A US letter page is 93.5 in². A common US tile is 144 in² (1 ft²). Credit card ≈ 7.1 in².
