If the UK ends up metricating our roadways, which will happen after HS2 is finished, I propose the following simplifications:

Distances up to 1 mi are rounded to the nearest 100 m.
eg 100 yd = 100 m, ⅓ mi = 500 m, ½ mi = 800 m, ⅔ mi = 1 km

Distances from 1 mi up to and incl 6 mi are rounded to the nearest 500 m.
1 mi = 1.5 km, 2 mi = 3 km, 3 mi = 5 km, 4 mi = 6.5 km, 5 mi = 8 km, 6 mi = 10 km

The spacing between each “mile” is slightly inconsistent, but an error rate of 100 - 200 m per mile is less than the tolerance rate for distance signs in the UK anyway

7 mi and above are converted to the nearest km

Once we fully metricate, new distance road signs will be measured to km scale, so the conversions above only matter to existing signs that would have to be relabelled

For speed limits:

20 mph = 30 km/h (-2 km/h)

30 mph = 50 km/h (+2 km/h)

40 mph is abolished and replaced with either 60 or 70 km/h, because speed limits must be in multiples of ten

50 = 80 km/h (± 0 km/h)

60 = 100 km/h (+4 km/h)

70 = rounded up to 120 km/h (~75 mph, +8 km/h) instead of down to 110 km/h (-2 km/h)

In addition, because all units will be in metric, there will be no need to duplicate languages in Wales, where signs must display English and Welsh words for imperial units, but won’t have to do the same for metric units since they’re symbols and not abbreviations
