Understanding the Acre

An acre is a unit of area that is commonly used in the United States and the UK for measuring large tracts of land. Historically, an acre was understood to be the amount of land tillable by a yoke of oxen in one day. Traditionally, it was defined as a strip of land 660 feet long and 66 feet wide or 43,560 square feet in total. Today, the acre remains a standard measurement in many national and local governments around the world, particularly in Anglophone countries. Despite the modern metric system, the acre is still widely used in real estate, agriculture, and land management to describe the size of plots.

How do you Calculate Acres?

Acreage can be calculated with two variables:

  • Plot length

  • Plot width
We can then use these values in the following formula to find the acreage of that plot:

Where:
  • A = Acreage

  • AP = Area of the plot of land

Understanding Your Results

Your result will be very simple and easy to understand. You will be given the exact number of acres your specific plot of land is based on your entries.

How to Use the Acreage Tool

We want to make every tool we offer simple and efficient. This calculator is exactly that, simple and easy to use. The steps include:

Example Calculation

Let's say we are out riding quads in the middle of a huge slab of land. We want to get a better idea of its acreage so we measure its length and width. We find the length to be 5,000 feet and the width to be 47,750 feet. We can use this tool to find the total acreage of this plot of land.

After plugging in the values into each field we hit calculate and get a total acreage of about 5,480.95 acres.

The History of Acreage

The word acre comes from the old English word æcer which means "field" or "open land". It is believed to began to be used around the year 1150 but this is not for certain. The word originally referred to the amount of land that a team of oxen can plow in one day. This made the word mean different amounts of land for different oxen packs and landowners, meaning it was rather unreliable.

In 1272, King Edward I of England declared that an acre was 40 rods (or 60 feet) long and 4 rods (66 feet) wide, forming a rectangle shape. This was equal to 43,560 square feet or about 4,047 square meters. When the British colony colonized North America they brought with them to term acre which is what allowed it to be adopted by the people there.

Fast-forward to today, the acre is a very important and commonly used metric for understanding lot sizes and general land sizes. It is easier to measure land with the help of technology, but the metric itself and the amount of land that equals one acre is still the same as it was hundreds of years ago.

Acres - Frequently Asked Questions

An acre is a unit of area used primarily in the United States and the UK. Historically, an acre was defined as the amount of land that could be plowed by a yoke of oxen in one day. Today, it is precisely defined as 43,560 square feet.

There are about 2.471 acres in a hectare. To convert hectares to acres, multiply the number of hectares by 2.471.

For irregularly shaped plots, you can divide the land into a combination of triangles and rectangles, measure each part separately, then sum up the areas. Tools like GPS land mapping or online mapping services can also help measure irregular plots.

Topography can significantly affect land measurement as it influences the actual surface area. Measurements taken solely from maps or overhead may not account for the undulating nature of the terrain, which can lead to inaccuracies in flat-area calculations.

If there is a discrepancy between calculated acreage and existing records, it is advisable to have a professional surveyor conduct a comprehensive survey. Discrepancies can arise from changes in land use, unclear boundaries, or errors in previous measurements.
