Take a look at EGHG for example, 16-1. You will see both RVR and CMV posted.
CMV on Approach plates
AOM for take-off and landing are either shown on Jeppesen instrument approach or aerodrome charts or on a separate minimums listing. Landing minimums will be shown as RVR, but values above 2000m will be designated as Converted Meteorological Visibility, prefixed “CMV”. Take-off minimums are shown without prefix because they are either RVR or VIS. Circling minimums are always visibilities which is indicated in the circling minimums box. For the separate minimums list- ings RVR, CMV and VIS are abbreviated as R, C and V. The following table is used to convert a reported VIS into RVR/CMV.
