Designed for students, engineers, and real estate professionals, this calculator effortlessly handles extreme values:

Scientific Notation: Type values like 1.5e-3 or 5E6 directly into the input box to instantly convert microscopic or massive land areas.
Instant Swapping: Click the arrows in the middle to reverse the conversion direction without losing your data.

The metric system uses base-10 logic, making area conversions mathematically straightforward.

Square Meter (m²)The SI derived unit of area. Equal to the area of a square with 1-meter sides.

Hectare (ha)Primarily used for land measurement. 1 Hectare = 10,000 m².

Square Kilometer (km²)Used for measuring large city or country areas. 1 km² = 1,000,000 m².

Are (a)An older metric unit for land. 1 Are = 100 m².

Commonly used in the US, UK, and real estate markets globally for property measurements.

Acre
Historically, the amount of land a yoke of oxen could plow in one day.
43,560 ft²
Square Foot (ft²)
Standard unit for real estate and housing floor plans.
0.0929 m²

For quantum mechanics and particle physics, standard measurements are far too large.

The Barn (b)

Used to express the cross-sectional area of nuclei and nuclear reactions. 1 Barn = 10^-28 m².

Certain regions maintain traditional land measurements for real estate and agriculture.

Used predominantly in southern Indian states like Kerala and Tamil Nadu.

1 Cent = 435.6 ft²

1 Cent = 40.46 m²

100 Cents = 1 Acre

A hectare is significantly larger than an acre. 1 Hectare is equal to roughly 2.47 Acres.

Measure the length and width of the room in feet. Multiply those two numbers together (Length × Width = Area in Square Feet).
