Just how fast is that thing?

For all you old-schooler and retro gamers out there who don't want to do the math and play games with 10 second rounds but are curious as to just what those movement speeds actually mean. I present this handy dandy table:

Movement per round to MPH
move .... mph
10 .... 1.136 mph
20 .... 2.3 mph
30 .... 3.4 mph
40 .... 4.5 mph
50 .... 5.7 mph
60 .... 6.8 mph
90 .... 10.2 mph
120 .... 13.6 mph
150 .... 17 mph
180 .... 20.5 mph
240 .... 27.3 mph

The math: feet per round x 600 / 5280 = mph

How about for really fast things rated in mph converted to ft per round?
Well here we go.

MPH to movement per round
mph .... ft/round
10 .... 88
20 .... 176
30 .... 264
40 .... 352
50 .... 440
60 .... 528
70 .... 616
80 .... 704
90 .... 792
100 .... 880
150 .... 1320
200 .... 1760
300 .... 2640
400 .... 3520
500 .... 4400
600 .... 5280

If rounds are 10 seconds long that means there are 600 rounds in an hour. So mph to feet per round is : mph x 5280 / 600
