How to convert acres to square kilometers (ac to km²)

The formula for converting acres to square kilometers is: km² = ac × 0.0040468564. To calculate the acre value in square kilometers first substitute the acre value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 acre in square kilometers we follow these steps:

km² = ac × 0.0040468564

km² = 1 × 0.0040468564

km² = 0.0040468564

In other words, 1 acre is equal to 0.0040468564 square kilometers.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 6 acres to square kilometers is:

Understand the conversion formula: km² = ac × 0.0040468564
Substitute the required value. In this case we substitute 6 for ac so the formula becomes: km² = 6 × 0.0040468564
Calculate the result using the provided values. In our example the result is: 6 × 0.0040468564 = 0.0242811384 km²

In summary, 6 acres is equal to 0.0242811384 square kilometers.

Converting square kilometers to acres

In order to convert the other way around i.e. square kilometers to acres, you would use the following formula: ac = km² × 247.10538147. To convert square kilometers to acres first substitute the square kilometer value into the above formula, and then execute the calculation. If we wanted to calculate 1 square kilometer in acres we follow these steps:

ac = km² × 247.10538147

ac = 1 × 247.10538147

ac = 247.10538147

Or in other words, 1 square kilometer is equal to 247.10538147 acres.

Conversion Unit Definitions

What is a Acre?

An acre is a unit of area measurement commonly used in land-related activities, particularly in agriculture, real estate, and land management. It is primarily used in the United States, the United Kingdom, and other countries with historical ties to British systems of measurement.

An acre is defined as a unit of area equal to 43,560 square feet or approximately 4,047 square meters. It is roughly equivalent to the area of a rectangle with one side measuring 66 feet and the other side measuring 660 feet.

To provide an example of an acre, imagine a rectangular plot of land with dimensions of 165 feet by 264 feet. To calculate the area of this plot in acres, we multiply the length (165 feet) by the width (264 feet) and divide the result by 43,560.

Area = (Length x Width) / 43,560

Area = (165 feet x 264 feet) / 43,560

Area ≈ 1 acre

So, the area of the rectangular plot is approximately 1 acre. This means that the plot covers a total surface area of 1 acre, which can be visualized as a rectangular region with sides measuring 66 feet by 660 feet.

Acres are commonly used in various applications related to land measurement and land use. In agriculture, for example, farms or fields may be measured in acres to determine their size or productivity. In real estate, land parcels, estates, or housing developments may be advertised or sold based on their acreage.

Additionally, the acre is often used in the context of land conservation, land management, and environmental planning. It helps quantify and manage natural habitats, protected areas, or the size of land needed for specific purposes.

It's important to note that the acre is primarily used in countries that follow the imperial system of measurement. In countries that use the metric system, such as most of Europe, land areas are typically measured in hectares (with 1 hectare approximately equal to 2.47 acres).

In summary, an acre is a unit of area measurement equal to 43,560 square feet or approximately 4,047 square meters. The example of a rectangular plot of land with dimensions of 165 feet by 264 feet demonstrates how the acre is used to quantify land areas in agriculture, real estate, and land management contexts.a

What is a Square Kilometer?

A square kilometer is a unit of area measurement in the metric system. It is commonly used to quantify large areas, such as landmasses, regions, or cities. The square kilometer is defined as the area of a square with sides measuring one kilometer in length.

To provide an example of a square kilometer, let's consider a city park that spans an area of 2 square kilometers. This means that the park covers a total surface area of 2 square kilometers, which can be visualized as a square-shaped region with sides measuring 1 kilometer each.

The square kilometer is a convenient unit for measuring extensive areas, especially when dealing with large-scale maps or land use planning. It is also commonly used in geographical studies, urban planning, and environmental assessments to describe the size and extent of various land features or geographical regions.

Another example can be the measurement of country sizes. For instance, Canada is known to have a land area of approximately 9.98 million square kilometers, making it the second-largest country by land area in the world.

In scientific research, the square kilometer is also employed in fields such as ecology and biodiversity studies. Scientists might assess the size of protected areas, habitat ranges, or the spread of certain species by measuring areas in square kilometers.

It's important to note that the square kilometer can be further subdivided or scaled up using metric prefixes. For instance, a square hectometer is equal to 10,000 square meters, while a square meter is equal to 1,000,000 square millimeters.

In summary, a square kilometer is a unit of area measurement representing the area of a square with sides measuring one kilometer in length. The example of a city park with an area of 2 square kilometers demonstrates how the square kilometer is used to quantify large-scale areas, such as landmasses, regions, or parks, in various fields and applications.
