About

In many parts of Europe and the CIS, the "Are" (often colloquially referred to as "Sotka" in some regions) is the standard unit for measuring private land plots. While official documentation often uses square meters (m²) or Hectares, real estate listings and garden planning frequently rely on Ares. One Are represents exactly 100 square meters.

This tool bridges the gap between technical surveying data and market descriptions. It is specifically tuned for real estate decision-making, offering precise conversion to 2 decimal places to match standard deed accuracy. It includes a "Reverse" function, acknowledging that users often need to work backward from a listed "6 Ares" plot to determine the exact construction footprint in square meters.

Formulas

The "Are" is a metric unit of area, defined as a square with 10 meter sides.

1 a = 10 m × 10 m = 100 m²

Conversion formulas:

{

Area_a = Area_m² ÷ 100Area_m² = Area_a × 100

Frequently Asked Questions

They are completely different units. An Are is a metric unit equal to 100 m². An Acre is an Imperial unit equal to approximately 4,046 m². One Acre is roughly 40 Ares.

Yes. In CIS countries (Russia, Ukraine, etc.), the term "Sotka" (meaning "hundred") is the colloquial name for an Are, because it equals exactly 100 square meters.

There are 100 Ares in 1 Hectare. The hierarchy is: 1 m² -> 100 m² (1 Are) -> 10,000 m² (1 Hectare).

For land plots, square meters result in large, unwieldy numbers (e.g., 1250 m²). Hectares are too big (0.125 ha). Ares provide a convenient, human-readable integer (12.5 Ares) that is easy to visualize and compare.
