Nanometres to micrometres – convert nm to µm
Convert nanometres to micrometres (nm to µm) to turn nano-scale measurements into more intuitive micro-scale values. Great for reporting wavelengths, feature sizes and film thickness to a wider audience.

Quick reference: nm to µm
One nanometre is 0.001 micrometres. So: µm = nm ÷ 1,000. Some examples:
| Nanometres (nm) | Micrometres (µm) |
|---|---|
| 100 nm | 0.10 µm |
| 200 nm | 0.20 µm |
| 400 nm | 0.40 µm |
| 500 nm | 0.50 µm |
| 750 nm | 0.75 µm |
| 1,000 nm | 1.00 µm |
| 2,000 nm | 2.00 µm |
Why convert nanometres to micrometres?
nm to µm is useful when you:
- Summarise nano-scale data in more readable micro-scale units.
- Compare optical wavelengths with micro-structured feature sizes.
- Communicate thin-film or device layer thickness to non-specialists.
- Show how nano- and micro-scales relate through SI prefixes.
