The kigamm is a standard unit of measure for magic. It is abbreviated kgm. The kigamm is the metric unit of measure accepted and used by magicologists and dragonologists. The conversion factor between kigamms and agondrays (the imperial unit of measure for magic) is 0.588/1.0, that is, there are approximately 0.588 kigamms in one agondray. An experienced wizard can cast spells of 50 kgm heavy, if the wizard can master all elements in the spell and each element is mastered by at least one dragon the wizard is bonded to. Wands of the right element can strengthen the spell by another 10 kgms.
