1 BPS is 0.5 units/second ...
And MPH is irrelevant in Blockland...
But it's pretty much possible to calculate RL scale distances if you compare the size of a blocko player?
A blocko head is 1 brick and a third wide.
A blocko head is 2/3 units.
A real head is 7 inches.
1 foot = 1.142857142857142857142857142
8571 units
1 yard = 3.428571428571428571428571428
5714 units
1 mile = 6034.285714285714285714285714
2857 units
(yes I'm aware that it's currently in x per second, not hour)
I suppose that that is a just way to scale a mile.
1 unit = 0.875000000000000000000000000
00011 ft
I'll just knock off all of those 0's.
