## How to Convert Square Meters to Other Common Units

Here’s how to convert square meters to other units of measurement.

One square meter is the same as 0.000001 square kilometers. To calculate square meters to square kilometers, multiply by 0.000001.

`Square kilometers = square meters x 0.000001`

## Square Meters to Acres Uses

The square meter is a measurement of area from the metric system or the International System of Units (SI). In countries that use the metric system, residents might use the square meter () to measure the area of a room, flooring, or field. It may also measure land in some instances, but the hectare is more commonly used for that purpose.

The acre (ac) is a measurement of land value from the Imperial and United States Customary Units system. The square meter is a globally accepted form of measurement, while the acre isn’t.

You may need to convert from square meters to acres to get a better sense of land area if you buy property abroad or live in a country like Canada that uses both the metric and Imperial systems.

## Dunam vs. Acre

The dunam is a measurement of land area originating from the former Turkish empire. The dunam was the Ottoman version of the English Acre of Greek Stremma. All of these measured the area of land one man could plow with a team of oxen per day.

While the old-world definition for the dunam was forty standard paces in breadth and length, the actual area varied by region – a dunam could range from 900 square meters to 2,500 square meters.

Many of the same countries still use the Dunam today, including Turkey, the Levant, and the United Arab Emirates. However, the definition has changed. In these parts of the world, one dunam is the equivalent of 100 square meters or 10,764 square feet – the same as 0.2471 acres.
Iraq also uses the dunam. However, the value differs from other places at 2,500 square meters or 0.25 ha.
