Reference points
| Diameter | Equivalent | Typical technical context |
|---|---|---|
| 20 nm | 0.020 µm | Lower end of current AP 3000-series family |
| 100 nm | 0.100 µm | Submicron optical and aerosol work |
| 900 nm | 0.900 µm | Upper end of current AP 3000-series family |
| 1 µm | 1,000 nm | Transition into micron-scale family |
| 10 µm | 10,000 nm | Liquid counting, optical microscopy and larger-particle work |
| 160 µm | 0.160 mm | Upper end of current AP 4000-series family |
Unit discipline
Avoid three common errors
- Do not write “micron” and “nanometer” interchangeably; 1 µm equals 1,000 nm.
- Do not infer certified mean from a rounded nominal size.
- Do not infer instrument compatibility from unit range alone.
