Distance
A distance value can be given either as a plain number or as a string with a unit suffix.
When given as a plain number, the value is interpreted in the unit documented for the specific field (for example millimeters or nanometers).
When given as a string, it consists of a number followed by a unit suffix, for example "5 mm", "1.5 cm", or "0.5 in". The following units are supported:
| Unit | Suffixes |
|---|---|
| Meter | m |
| Centimeter | cm |
| Millimeter | mm |
| Micrometer | um, µm |
| Inch | in, inch, " |
