It matters not which system you use the formula for calculating overall stopping distance is the same, whether you use mph and feet or metres per second and metres.
Overall stopping distance = thinking distance PLUS Braking distance
Thinking distance = v = speed ( either in feet or metres)
Braking distance = v squared divided by 20
It's just easier to do it in feet and mph. No idea what the current Highway Code says but the maths doesn't change.
Please note these are averages. Reaction times vary and so do cars braking abilities.
