samizdat said:MPASquared implies MPA multiplied by itself. The square root of MPASquared would in fact be MPA. MPA times two would be simply 2MPA although of course if MPA equals 2 then 2MPA would equal MPA squared but certainly not the square of MPA.Ok, maybe it is just my semantics and we still arrive at the same result? Let say MPA is the numeric 3. Then MPAsquared is 9 (3 times 3)?
