Units explained
Square Yoctometer
A square yoctometer is a metric unit of area equal to one square yoctometer (10⁻²⁴ m × 10⁻²⁴ m = 10⁻⁴⁸ m²). It is the smallest SI prefix-derived area unit defined and exists primarily for theoretical completeness.
Derived by squaring the yoctometer (10⁻²⁴ m), which uses the SI prefix yocto- adopted by the CGPM in 1991. The yocto- prefix originates from the Latin 'octo' (eight), referring to the 10⁸ thousand-grouping in the power-of-thousand scheme.
Square yoctometers have no current practical application. The yoctometer scale itself lies far below any physically measurable length, including the Planck length. The unit is included for SI catalogue completeness.
SI prefix yocto- adopted in 1991; square area defined by mathematical squaring.
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.
Square Yoctometer to Square Micrometer conversion formula
The relationship between square yoctometers and square micrometers:
To convert square yoctometers to square micrometers, multiply the value in square yoctometers by 1e-36. To reverse, multiply square micrometers by 1e+36.

Step-by-step: convert square yoctometers to square micrometers
- Write down the value in square yoctometers (ym²).
- Multiply that value by the factor 1e-36.
- The product is the equivalent value in square micrometers (µm²).
- To reverse, multiply the square micrometer value by 1e+36.
Worked examples
Example 1 — Convert 1 ym² to µm²:
1 × 1e-36 = 1e-36 µm²
Example 2 — Convert 100 ym² to µm²:
100 × 1e-36 = 1e-34 µm²
Real-world example — Molecular dimensions
The diameter of small molecular structures (around 2 square yoctometers) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.
2 ym² × 1e-36 = 2e-36 µm²
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 yoctometers can be re-expressed in square micrometers for direct comparison with another instrument's calibration data sheet.
800 ym² × 1e-36 = 8e-34 µm²
