200 micron to mm: 0.2 mm
200 microns is 0.2 mm, or 0.00787 inch. As a sieve opening it is about 73 mesh on the ASTM E11 series. For a wedge wire screen, specify it directly as a 200 micron (0.2 mm) slot.

Equivalent wedge wire slot: 200 micron (0.2 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 200 micron opening
As a general reference on the Wentworth grade scale, particles smaller than 200 µm pass: very fine sand, 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 200 micron (0.2 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.
