Units explained
Square Picometer
A square picometer is a metric unit of area equal to 10⁻²⁴ m². It is used at atomic and molecular scales.
Derived by squaring the picometer (10⁻¹² m). The pico- prefix comes from the Italian 'piccolo' (small).
Square picometers appear in computational chemistry, surface science, and X-ray crystallography when discussing atomic cross-sections and very small surface patches.
SI prefix pico- adopted in 1960.
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 Picometer to Square Yoctometer conversion formula
The relationship between square picometers and square yoctometers:
To convert square picometers to square yoctometers, multiply the value in square picometers by 1e+24. To reverse, multiply square yoctometers by 1e-24.

Step-by-step: convert square picometers to square yoctometers
- Write down the value in square picometers (pm²).
- Multiply that value by the factor 1e+24.
- The product is the equivalent value in square yoctometers (ym²).
- To reverse, multiply the square yoctometer value by 1e-24.
Worked examples
Example 1 — Convert 1 pm² to ym²:
1 × 1e+24 = 1e+24 ym²
Example 2 — Convert 100 pm² to ym²:
100 × 1e+24 = 1e+26 ym²
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 picometers can be re-expressed in square yoctometers for direct comparison with another instrument's calibration data sheet.
800 pm² × 1e+24 = 8e+26 ym²
Real-world example — Molecular dimensions
The diameter of small molecular structures (around 2 square picometers) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.
2 pm² × 1e+24 = 2e+24 ym²
