300 micron to mm: 0.3 mm
300 microns is 0.3 mm, or 0.0118 inch. As a sieve opening it is 50 mesh on the ASTM E11 series. For a wedge wire screen, specify it directly as a 300 micron (0.3 mm) slot.

Equivalent wedge wire slot: 300 micron (0.3 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.

What passes a 300 micron opening
As a general reference on the Wentworth grade scale, particles smaller than 300 µm pass: fine sand, 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 300 micron (0.3 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.
