is there anyone who can explain me difference between the reduced Planck's constant and Planck's constant? SIMPLY. I know equation between this but... I don't understand it.

If I express the Planck's length by √(hG/c), it is bad? There have to be reducet Planck's constant, bud why?

Thanks very much,

sorry for my bad English
