Ok, I'm trying to figure this out. I recently noticed that a few add-ons have used the word "meter", including Badspot. In /cleearfarawaybricks, it mentions the word meter, and has 1000 as a distance. So, as soon as I remembered to do it, I'm converting the box train stuff into MPH with several options on July 31.
Here is what I have, X being the speed in half-BPS(bricks per second).
half-BPS's are just the default speed measurement.
X would be meters per second
x = x / 1000 / 1.6093
(this isn't a scripting example)
1000 = meters in a kilometer
1.6093 = kilometers in a mile
Ok, now we have miles per second.
x = x * 60 * 60
Now we have miles per minute, then miles per hour(of course we can use times 360)
Now, does it all sound right? My calculation appears to be correct.
