Numerical values are in their Base unit indexed. You can also enter a desired unit as a search operator in square brackets []. [9]
Values can be searched for in inch notation (e.g. 3 1/2 )
A fractional representation is evaluated as inches by default and a conversion to mm takes place automatically in the background so that mm values are also found.
1/2
1 1/2
If you want to search explicitly for mm with fractional representation, you must add "mm" in square brackets.
1/2 [mm]
If you want to search explicitly for inches with a decimal value, you must add "inch" in square brackets.
0.5 [inch]
You can also search for inch by specifying "from-to".
1/2 - 3/4
1 1/2 - 1 3/4
For from-to specifications, the unit can also be specified after the values.
1 1/2 [inch] - 1.75 [inch]
If there is no explicit specification, the last token defines the unit.
The following search therefore still leads to inch results, as the fractional number is automatically evaluated as an inch.
1.5 - 1 3/4
Inch values could also be part of order numbers, for example.
