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 Nanometer
A square nanometer is a metric unit of area equal to 10⁻¹⁸ m² (1 nm × 1 nm). It is the standard unit in nanotechnology and surface science for expressing the area of nanoscale structures.
Derived by squaring the nanometer (10⁻⁹ m). The nano- prefix comes from the Greek 'nanos' (dwarf).
Square nanometers are used to express the surface area of nanoparticles, the footprint of single molecules adsorbed on surfaces, and the active area of nanoscale electronic devices.
Nanometer adopted into SI in 1960; widespread use in nanotechnology grew through the 1990s and 2000s.
Square Picometer to Square Nanometer conversion formula
The relationship between square picometers and square nanometers:
To convert square picometers to square nanometers, multiply the value in square picometers by 1e-6. To reverse, multiply square nanometers by 1000000.

Step-by-step: convert square picometers to square nanometers
- Write down the value in square picometers (pm²).
- Multiply that value by the factor 1e-6.
- The product is the equivalent value in square nanometers (nm²).
- To reverse, multiply the square nanometer value by 1000000.
Worked examples
Example 1 — Convert 1 pm² to nm²:
1 × 1e-6 = 1e-6 nm²
Example 2 — Convert 100 pm² to nm²:
100 × 1e-6 = 1e-4 nm²
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-6 = 2e-6 nm²
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 nanometers for direct comparison with another instrument's calibration data sheet.
800 pm² × 1e-6 = 0.0008 nm²
