What size of sharkbite should I use on 10mm copper pipes in old mobile trailer?

[ELY_M]

I know sharkbite fittings and valves come in inches for sizes.
I am not sure what size would fit 10mm OD old copper pipes.
I need to set up new water lines with new valves under kitchen sink.
the copper pipes are 10mm OD according to the measurement caliper I have.
The mobile home was made in early 70s. I have been here for many years.
