Volvo probably stores the data in the Flash memory as Kilometers.
Most car manufacturers outside the USA do this.
The display of the mileage is then easily adapted to Miles by a simple mathematical calculation.
But that is not your issue.
You issue is wanting to fitted a 2nd hand DIFFERENT instrument cluster to the vehicle, and thus you will end up with a configuration in the vehicle that was not anticipated by the vehicle manufacturer.
The cluster you fit will have a different part number to the original cluster, and it will be not the anticipated cluster for the vehicle.
Volvo never anticipate that a vehicle be reconfigured from eg a USA market to a European market, or a Japanese to a European market, etc.
You MAY thus have firmware and software controls in place that cause further problems.
I say MAY as I am not sure if the cluster itself is a programmable item.
I am not sure what your results will be.
The DIM inside the cluster IS programmable, and must be coded with the correct data for the market that the car operates in. This holds some basic info such as time and date format, display in °C or °F, etc.
But how does the cluster handle differences in vehicle coding when it comes out of vehicle A and is fitted to vehicle B?
I don't know.
Even if you do swap of the cluster from the original cluster in MPH to a cluster in KMPH, you may continue to have problems as the vehicles core market data, as stored in the CEM, contains a coding item that states what type of instrument cluster is fitted (MPH or KMPH) and other market relevant data
So while I am not saying this is impossible, I am saying you need to be prepared for the event that it may be more difficult than you think.
I suggest you find a supplier that is willing to provide you a cluster on a "try and see" basis with some form of money back if not satisfied.
