What is Acre?

The acre is a popular measurement of land in North America and the Caribbean. It measures 4,047 square meters (43,560 square feet) in size. This quantity generally corresponds to 40% of a hectare. Surprisingly, the acreage can be traced back to the Middle Ages.

 It was defined as the amount of land that could be ploughed in a single day using an ox. A football field is around 76 percent the size of an acre. Many suburban lots range in size from a quarter to a fifth of an acre.

In the imperial and US customary systems, the acre is a unit of land area. It is usually described as the area of one chain by one furlong (66 by 660 feet), which is exactly equivalent to 10 square chains, 1640 of a square mile, 4,840 square yards, or 43,560 square feet, and 4,047 m2, or roughly 40% of a hectare. According to the 1959 International Yard and Pound Agreement, one acre is equal to 4,046.8564224 square meters. The acre was often abbreviated as ac, but it was more commonly written out as "acre."


The word "acre" comes from Old English cer, which originally meant "open field" and is related to the west coast. Norwegian kre, Icelandic akur, Swedish ker, German Acker, Dutch akker, Latin ager, Sanskrit ajr, and Greek ajr are all variations of the same word (agros). In English, aker was a defunct alternative spelling.

An acre is defined as "40 perches [rods] in length and four in breadth," or 220 yards by 22 yards, according to the Act on the Composition of Yards and Perches, which dates from circa 1300. An acre was roughly the amount of ground that a yoke of oxen could till in one day, as seen in the box on the right.

Equivalence to other area units:

1 acre (both variants) is equal to 0.404685642 hectares and the following customary units:

  • 66 feet × 660 feet (43,560 square feet)
  • 10 square chains (1 chain = 66 feet = 22 yards = 4 rods = 100 links)
  • 1 acre is approximately 208.71 feet × 208.71 feet (a square)
  • 4,840 square yards
  • 43,560 square feet
  • 160 perches. A perch is equal to a square rod (1 square rod is 0.00625 acre)
  • roods
  • A furlong by a chain (furlong 220 yards, chain 22 yards)
  • 40 rods by 4 rods, 160 rods2 (historically fencing was often sold in 40 rod lengths[42])
  • 1⁄640 (0.0015625) square mile (1 square mile is equal to 640 acres)


What do we know about Hectacre?

In the metric system, a hectare is equal to 100 acres, or 10,000 square meters, and in the British Imperial System and the United States Customary measure, a hectare is equal to 2.471 acres. The name comes from the Latin word area and the Greek word hect, which is an irregular abbreviation of the word hundred. 

Despite the fact that the acre is the primary metric unit of land measurement, the hectare is more usually employed in practice. A hectare is equal to a djerib in Turkey, a jerib in Iran, a gong qing in mainland China, a manzana in Argentina, and a bunder in the Netherlands, according to subsequent definitions.

A hectare is around 2.47 acres, and an acre is about 0.405 hectare.

Hector's relationship with Acer:

The link between a hectare and an acre is straightforward. When it comes to selling and buying land/plots, it's especially important to understand the underlying relationship and number for 1 hectare to an acre.

In all, 1 hectare is 2.471053815 acres, or 2.471053815 acres.

2.471053815 acres = 1 hectare

This knowledge can be put to good use in converting hectares to acres.

The hectare to acre conversion should also include the reverse numbers, such as 1 acre = 0.4046856422 hectares, or we can write it as-

0.4046856422 = 1 acre

What is Square yard?

The square yard (Northern India: gaj, Pakistan: gaz) is an imperial and customary unit of area in the United States that was once widely used in the English-speaking world but is now mostly displaced by the square meter.

 However, in the United States, the United Kingdom, Canada, Pakistan, and India, it is still widely used. It is the area of a square with sides measuring one yard (three feet, thirty-six inches, 0.9144 meters).

One square yard is equivalent to:

What is meant by Square kilometer in measurements?

The square kilometer (American spelling) is a multiple of the square meter, the SI unit of area or surface area. Its symbol is km2. The square kilometer, often known as a square mile, is a multiple of the square meter, the SI-derived unit for area. "Kilo" is the prefix for 103 in the metric system. 

A square kilometer is also known as a square kilometer. The abbreviation for square kilometers is sq km, whereas the abbreviation for square kilometers is km2. 1 square kilometer, for example, can be expressed as 1 sq km or 1 km2.

1 square kilometer equals:

  • 100 hectares/1,000,000 square meters (ha)

It's also roughly equivalent to:

  • 0.3861 square miles
  • 247.1 acres

How to convert square kilometers to acres?

Square kilometer to acre conversion:

Square kilometers and acres are both units used to measure area

Multiply the area by the conversion ratio to convert a square kilometer measurement to an acre measurement. Because one square kilometer equals 247.105381 acres, you can convert using this simple formula:

247.105381 acres = square kilometers

The area in acres is calculated by multiplying the square kilometers by 247.105381.

How to convert square kilometer to acre?

Square Yards to Acres conversion:

In 1 acre, there are 4840 square yards. Multiply your number by 4840 (or divide by 0.00020661157024793) to convert acres to square yards.
