Units explained
Square Micrometer
A square micrometer is a metric unit of area equal to 10⁻¹² m² (1 µm × 1 µm). It is widely used in microscopy, semiconductor manufacturing, and cell biology.
Derived by squaring the micrometer (10⁻⁶ m). The micro- prefix comes from the Greek 'mikros' (small).
Square micrometers express the cross-sectional area of cells, semiconductor features, microfluidic channels, and microscopy fields of view. Modern CPU transistors have feature areas of a few nm² to tens of nm².
Micrometer adopted into SI in 1960.
Are
An are is a metric unit of area equal to 100 square meters. It is used in some European countries for land measurement, especially for smaller plots like vineyards and gardens.
Introduced as part of the French metric system in 1795. The name comes from the Latin 'area' meaning surface or open ground.
Ares are still used in some European countries (especially Switzerland and France) for small-plot land measurement. In Switzerland, an are is a common unit for vineyard size. Most modern contexts prefer square meters or hectares.
Defined in 1795 in France as part of the original metric system.
Square Micrometer to Are conversion formula
The relationship between square micrometers and ares:
To convert square micrometers to ares, multiply the value in square micrometers by 1e-14. To reverse, multiply ares by 1e+14.

Step-by-step: convert square micrometers to ares
- Write down the value in square micrometers (µm²).
- Multiply that value by the factor 1e-14.
- The product is the equivalent value in ares (a).
- To reverse, multiply the are value by 1e+14.
Worked examples
Example 1 — Convert 1 µm² to a:
1 × 1e-14 = 1e-14 a
Example 2 — Convert 100 µm² to a:
100 × 1e-14 = 1e-12 a
Real-world example — Wavelengths across the spectrum
Optical and atomic-scale phenomena are routinely cross-converted between sub-micron units. A photon of wavelength 800 square micrometers can be re-expressed in ares for direct comparison with another instrument's calibration data sheet.
800 µm² × 1e-14 = 8e-12 a
Real-world example — Molecular dimensions
The diameter of small molecular structures (around 2 square micrometers) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.
2 µm² × 1e-14 = 2e-14 a
