Units explained
Square Meter
A square meter is the SI base unit of area, defined as the area of a square with sides of one meter. It is the universal scientific unit for area.
Defined by squaring the meter, which was redefined in 2019 in terms of the speed of light. The meter itself was originally proposed by the French Academy of Sciences in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.
Square meters are the universal SI unit for area, used in real estate (most countries outside the US/UK), construction, physics, engineering, materials science, biology, and nearly all scientific contexts worldwide.
Meter adopted as SI base unit in 1960; current exact definition via speed of light dates to 2019.
Dunam (Metric)
A metric dunam is a unit of land area equal to exactly 1000 m² (0.1 hectare or about 0.247 acre). Used widely in Israel, Turkey, and the Middle East.
Originally an Ottoman unit of variable size (see Ottoman dunam). The metric dunam was standardized at exactly 1000 m² in the 20th century for ease of conversion.
Metric dunams are the standard land measurement unit in Israel for both residential and agricultural property. Also widely used in Turkey, Cyprus, and other former Ottoman territories.
Standardized at 1000 m² in 20th century; Ottoman origin.
Square Meter to Dunam (Metric) conversion formula
The relationship between square meters and dunams:
To convert square meters to dunams, multiply the value in square meters by 0.001. To reverse, multiply dunams by 1000.

Step-by-step: convert square meters to dunams
- Write down the value in square meters (m²).
- Multiply that value by the factor 0.001.
- The product is the equivalent value in dunams (dunam).
- To reverse, multiply the dunam (metric) value by 1000.
Worked examples
Example 1 — Convert 1 m² to dunam:
1 × 0.001 = 0.001 dunam
Example 2 — Convert 100 m² to dunam:
100 × 0.001 = 0.1 dunam
Real-world example — Metric distance scale-up
One thousand square meters equals one dunam (metric) — the running distance for a 1K race or the standard metric kilometre-scale step. The simple thousand-fold conversion is the most-used metric distance translation.
1000 m² × 0.001 = 1 dunam
Real-world example — Imperial mile arithmetic
5,280 square meters equals exactly one dunam (metric). American hikers tracking elevation gain in the smaller unit but trail length in the larger one use this constant every time they read a topographic map.
5280 m² × 0.001 = 5.28 dunam
Real-world example — Imperial yard-to-mile scale
1,760 square meters equals exactly one dunam (metric). American athletes and surveyors use this conversion to translate distances quoted in the smaller imperial unit into recognizable fractions of the larger geographic one.
1760 m² × 0.001 = 1.76 dunam
