10 cm
The following are examples of orders of magnitude for different lengths.
To help compare different orders of magnitude, the following list describes various lengths between 1.6×10−35 meters and meters.
(also called one micron)
To help compare different orders of magnitude this page lists lengths between 10−7 and 10−6m (100 nm and 1 µm).
To help compare different orders of magnitude this page lists some items with lengths between 10−6 and 10−5m (between 1 and 10 micrometres, or µm).
