100 micron to mm: 0.1 mm
100 microns is 0.1 mm, or 0.00394 inch. As a sieve opening it is about 150 mesh on the ASTM E11 series. For a wedge wire screen, specify it directly as a 100 micron (0.1 mm) slot.

Equivalent wedge wire slot: 100 micron (0.1 mm)
Wedge wire is specified by its slot directly, so a wedge wire screen has no mesh count. Quote the slot in mm or microns.
Your inputs and results go into the quote form, so an engineer can check them against your operating conditions.

What passes a 100 micron opening
As a general reference on the Wentworth grade scale, particles smaller than 100 µm pass: silt, clay. Real separation also depends on particle shape, the screen's open area and how the screen is loaded.
The wedge wire equivalent
A wedge wire screen is specified by its slot, so the equivalent is a 100 micron (0.1 mm) slot. Because the V-shaped wire widens behind the slot, particles that pass the face do not wedge in it. See mesh to micron and slot size and how to choose slot and open area.
