Why would you need to know; any specific requirement for landing?
The approach RVR limits (first third) are primarily associated with having the required visual reference at DH, which will be sufficient for the type of operation; auto-land, or manual-land reversion, etc.
Lower RVRs (mid, end) generally consider the ability to maintain directional control when on the runway; e.g. auto rollout revert to manual, or manual, etc. (As per FlightDetent #9)
The different tasks are reflected in the RVR values, and also that during landing the aircraft is decelerating.
There may be a different interpretation for takeoff, e.g. having to maintain directional control for an RTO.
Most airports limit operations to 75m RVR due fire rescue limitations.
Use the highest autobrake setting.
