Can someone explain the blast radius (from the center outward) of 500 milli creepers? (I assume that 1 creeper = 1000 milli creepers)
I'm asking this because, on the FTB wiki, under power armor, it says the plasma cannon has a blast radius of 500 milli creepers. I'm trying to figure out what that means in an actual measurement.

Millicreepers is a way of measuring blast radiuses (radii?). A creeper's blast radius is an easy to compare to as it is a common vanilla feature. As you said and the FTBWiki states, the blast radius of the plasma cannon is 500 millicreepers (.5 creepers) or 1/2 the radius of a creepers explosion.
Reference this picture:
The explosion on the right is that of a regular creeper (the one on the left is a charged creeper). Now halve that and you have the explosion size for the plasma cannon. Take note that with harder blocks the explosion radius will be smaller. If you are curious you can find the list of block blast resistances here: http://minecraft.gamepedia.com/Explosion#Blast_resistance
Extra Info: On the Explosion page of the Minecraft wiki, the power levels of explosions are also listed. Creepers are listed as having a power level of 3. So the plasma cannon would rate a level of 1.5 which is slightly higher than that of a ghast fireball or wither heads.
