# Convert square meter to acre

## What is a square meter?

Square meters is the common option for the evaluation of areas in different countries. They are based on a standard internationally recognized unit and are designated as m^2.

To understand what is a square meter, imagine a corresponding geometric figure with all sides equal to 1 m or 100 cm. That is exactly an area that is established as one m^2.

Basically, this metric represents the product of the multiplication of two numerical values, namely the length and width of an object. Its length is multiplied by the width. The result obtained is an area or numerical characteristic of the plane. Most often, this parameter is encountered when calculating the space of a room, while buying land or thinking about the amount of building materials’ consumption.

Altogether, it is quite convenient and common in everyday life and corresponds to 0.000001 sq. kilometers or 0.0001 hectares.

## What is an acre?

An acre or ac for short is still one of the popular and common metrics in Great Britain and other English-speaking regions of the world. It is utilized in trade and can be used officially, as its correspondence to the standard options is established.

The history of this metric goes back to the Middle Ages. This term was utilized to evaluate the area cultivated by one peasant with one ox per day. Then, the definition was changed a bit and told that one acre corresponds to an area with the sides of 1 chain by 1 furlong or 66 feet by 660 feet.

Only in the middle of the XX century, scientists determined acre as nearly 4046.856 square meters, 0.004 square kilometers, 0.405 ha, or 4840 square yards. Therefore, this option keeps its position on the land market and can be easily recalculated to other units, including those from the unified system.

## How to Convert square meter to acre

When it comes to the transformation of square meter to acre, there is a need to keep in mind their correlation. Both these options are utilized for area evaluation but are quite different in meaning. Thus, 1 sqm to acre corresponds to 0.000247105.

This coefficient is often taken as an approximate value of 0.0002. Then, for instance, 3 sq meter to an acre will give 0.0002 x 3 = 0.0006 and so on. This is how one can convert m2 to acre by solving such a one-step equation.

## How many square meter in a acre

If we know that there are 0.000247105 acres in one sqm, then we can recalculate these values back. For this, we have to divide 1 by 0.000247105. The answer is 4046.856422 and this is exactly the number of m^2 in one acre.
