Please provide values below to convert square foot [ft^2] to hectare [ha], or *vice versa*.

### Square foot

**Definition:** A square foot (symbol: sq ft) is a unit of area used in the imperial and US customary systems (UCS). It is defined as the area of a square with one-foot sides. One square foot equals 144 square inches.

**History/origin:** The origin of the square foot can be seen in the term itself. It is a measurement derived from the area of a square with a side length measured in feet.

**Current use:** The square foot is mainly used in the United States but is also used to some extent in countries such as the United Kingdom, Canada, Malaysia, Singapore, Pakistan, Bangladesh, India, and Hong Kong. In these countries, area in real estate, architecture, and of interior spaces is often specified in terms of square footage.

### Hectare

**Definition:** A hectare (symbol: ha) is a unit of area that is accepted in the International System of Units (SI). It is primarily used to measure land area. One hectare is equal to 10,000 square meters and is equivalent to approximately 2.471 acres.

**History/Origin:** The hectare was first introduced in 1795 as part of the metric system. The term hectare is derived from the metric prefix "hecto," denoting a factor of one hundred, and the metric area "are," a metric unit for measuring area that has fallen out of use in SI. The "are" is still used in certain areas when referencing real estate, particularly in India, Indonesia, and a number of European countries.

**Current use:** Hectares are primarily used to measure land area around the world. Even though it is not an SI unit (just a unit accepted for use with SI) the SI brochure states that the use of the hectare is expected to "continue indefinitely."
