1 inch = 333', or 111 yards, or about 3" per 1000' of RPG range 1 MDC = Main body MDC / 25 (rd up) 1 MD = Maximum weapon damage / 20 (rd up) 1 Turn = 9 seconds 1 MP = 25 mph (rd normal)
Weapon ranges are often modified towards a 12-24" range (either added or reduced) to make it more friendly to most tabletop gamers.
Speeds are often increased or decreased to a 5-10" range, so things aren't too slow or too fast.
MDC/MD are almost always right on.
Note that RRT uses the SECOND EDITION RPG statistics, not the 1st. For example in 1E the Veritech had 250 MDC, while in 2E the Valkyrie has 350 MDC. Don't bother trying to use 1E stats, they changed a lot. Heck, a Regult in 1E had 50 MDC and now its 125!
