Do you want to see other calculation tools?

The above online calculator is a tool to convert surface units (metric area measurements) to another value indicated by the user. With the surface converter you can convert the measurement of square meters (), hectares, square miles (mi²), square kilometers (km²), square feet, acres, inches, etc., to other area magnitudes.

How does the surface measurement converter calculator work?

The calculator for converting surfaces allows you to enter a value in a metric surface unit, select the destination unit, and automatically provides the converted value based on the equivalence between both area units.

  1. Selection of the source surface unit:
    • The top part contains a dropdown menu where you can select the surface unit you have as an input value (for example, square meters, hectares, acres, square feet, etc.).
  2. Entering the value to convert to another surface measurement:
    • Just below, there is the field to enter the numerical value you want to convert.
  3. Selection of the destination surface magnitude:
    • After entering the value, there is another dropdown menu where you select the unit to which you want to transform the entered value.
  4. The surface conversion is done automatically:
    • The calculator converts the provided surface units to the assigned value according to the conversion interest. Everything is automatic! Additionally, you will have an informative field with the equivalent information.

At the bottom of the online surface converter, it shows the exact equivalence: for example, from “1 hectare = 10,000 square meters”, which provides a precise reference for the conversion of surface magnitudes. Some examples of use in the calculator for converting between areas:

  • From square meters (m²) to square feet (ft²):
    • Entered value: 100 m²
    • Conversion: 100 m² to ft²
    • Result: 100 m² ≈ 1076.39 ft²
  • From hectares (ha) to acres:
    • Entered value: 2 hectares
    • Conversion: 2 hectares to acres
    • Result: 2 ha ≈ 4.9421 acres
  • From square kilometers (km²) to square miles (mi²):
    • Entered value: 1 km²
    • Conversion: 1 km² to mi²
    • Result: 1 km² ≈ 0.3861 mi²

Frequently asked questions about converting area or surface units – FAQ


What is a unit of area and what is it used for?

Units of area are used to measure surfaces, such as land, floors, or any two-dimensional space. For example, square meters (m²) are common for measuring rooms, while hectares (ha) are used for agricultural fields.

How do I convert between square meters and hectares?

To convert from square meters to hectares, divide the number of square meters by 10,000 (1 ha = 10,000 m²). If you have 50,000 m², divide it by 10,000, the mathematical calculation would be: 50,000 ÷ 10,000 = 5 ha.

What is the difference between an acre and a hectare?

An acre (ac) is a unit of measurement mainly used in countries with the imperial system, such as the United States and the United Kingdom, and the hectare in the metric system. An acre is approximately 0.4047 hectares.

How do I convert square feet to square meters?

To convert from square feet (ft²) to square meters (m²), multiply the value of the square feet by 0.092903. For example, if we have 500 ft², the calculation would be 500 × 0.092903 = 46.45 m².

How do I convert square kilometers to square miles?

To convert from square kilometers (km²) to square miles (mi²), multiply the area in square kilometers by 0.386102. The formula would be: Area in mi² = Area in km² × 0.386102

How do I convert square feet to square yards?

To convert square feet (ft²) to square yards (yd²), divide the area in square feet by the value of 9. The mathematical calculation would be Area in yd² = Area in ft² ÷ 9

What is a square mile and how does it compare to a square kilometer?

A square mile (mi²) is an imperial unit – mainly used in the United States – that measures very large areas, such as cities or regions. A square mile is equivalent to 2.58999 square kilometers (km²).

What is a hectare and where is it used?

A hectare (ha) is equivalent to 10,000 square meters and is commonly used to measure large surfaces such as fields, forests, rural properties, or soccer fields.

How do I convert square kilometers to square miles?

To convert square kilometers (km²) to square miles (mi²), multiply the value of km² by 0.3861. For example, if we have 10 km², the calculations would be 10 × 0.3861 = 3.861 mi².

Why can an area be in square meters and not in liters?

Because area units (like m²) measure surfaces in two dimensions (width and length), while liters measure volumes in three dimensions (width, length, and height). They are different concepts.

What is an acre and what is it used for?

An acre (ac) is a unit of surface used mainly to measure land in the United States and the United Kingdom. An acre is equivalent to 4,046.86 m², a little less than half of a hectare.
