Nanoscale Size Reference
Copper Nanopowder (2–60 nm (avg. 25 nm)) is far finer than any US mesh/sieve can measure — even the finest standard sieve number (12000 mesh) only resolves down to 1 µm (1,000 nm), still far coarser than the particle sizes on this page. Particle size for true nanopowders is specified directly in nanometers, as in the table above, not by mesh number. For reference, here is how nanometers relate to microns and millimetres:
| Nanometer (nm) | Micron (µm) | mm | Remarks |
|---|---|---|---|
| 1 | 0.001 | 0.000001 | DNA helix width (≈2 nm) |
| 5 | 0.005 | 0.000005 | |
| 10 | 0.01 | 0.00001 | |
| 20 | 0.02 | 0.00002 | |
| 50 | 0.05 | 0.00005 | |
| 100 | 0.1 | 0.0001 | |
| 200 | 0.2 | 0.0002 | |
| 500 | 0.5 | 0.0005 | Mid-range of visible light wavelength (≈400–700 nm) |
| 1,000 | 1 | 0.001 | = finest standard sieve, 12000 mesh |
| 10,000 | 10 | 0.01 | |
| 74,000 | 74 | 0.074 | = 200 mesh, a common bulk-powder sieve grade |
