# Convert Square Meter to Hectare

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

### Square meter

**Definition:** The square meter, or square metre (symbol: m^{2}), is an SI (International System of Units) derived unit of area. It is defined as the area of a square with side measures of one meter, where the meter is currently defined as the distance traveled by light in 1/299 792 458 of a second when expressed in the unit m·s^{-1}, where the second is defined in terms of the cesium frequency, ΔνCs.

**History/origin:** Area is commonly represented in the form of a square with sides of a specific unit of length, written as "square" followed by the chosen unit of length. The square meter is one of many such units and is derived from the area of a square with sides of one meter.

**Current use:** The square meter is the SI unit of area, though it is considered an SI derived unit rather than an SI unit. It is most often used to measure land area such as rooms, houses, and large plots of land. As with other SI units, the standard prefixes can be applied to the square meter to signify decimal multiples. Examples of this include the square decameter, square hectometer, and square kilometer. However, these larger measurements are typically not used, as the square meter is already a fairly sizeable measurement, and these prefixes would be referring to large areas that are not commonly referenced. Note that the square meter and its multiples and submultiples are squared, making a square decameter 10,000 times the size of a square meter even though a decameter is 100 times the size of a meter.

### 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."

Square Meter [m^2] | Hectare [ha] |
---|---|

0.01 m^2 | 1.0E-6 ha |

0.1 m^2 | 1.0E-5 ha |

1 m^2 | 0.0001 ha |

2 m^2 | 0.0002 ha |

3 m^2 | 0.0003 ha |

5 m^2 | 0.0005 ha |

10 m^2 | 0.001 ha |

20 m^2 | 0.002 ha |

50 m^2 | 0.005 ha |

100 m^2 | 0.01 ha |

1000 m^2 | 0.1 ha |

### How to Convert Square Meter to Hectare

1 m^2 = 0.0001 ha

1 ha = 10000 m^2

**Example:** convert 15 m^2 to ha:

15 m^2 = 15 × 0.0001 ha = 0.0015 ha
