Numerical values are indexed in their base unit. They can also be searched with a specified unit as search operator in brackets [].^[7]

You can search values in inch notation (e.g. 3 1/2)

A notation as fraction will be treated as inch by default and in the background, a conversion to mm will happen, so that mm values can also be found.

1/2

1 1/2

If you want to search for "mm" with a fraction, you have to add "mm" in square brackets.

Note Only if the unit is explicitly stated, searching is exclusively numerical, otherwise textual.

1/2 [mm]

When wanting to explicitly search for Inch you have to add "inch" in square brackets.

Note Only if the unit is explicitly stated, searching is exclusively numerical, otherwise textual.

0.5 [inch]

Also with inch, you can search "from-to".

1/2 - 3/4

1 1/2 - 1 3/4

Also when using from-to statements the unit can be added behind.

1 1/2 [inch] - 1.75 [inch]

If there is no explicit statement, the last token defines the unit.

The following search leads to Inch results, because the fraction is automatically interpreted as Inch.

1.5 - 1 3/4

Inch values can also be part of order numbers, for example.
