    Does percentage of uncertainty = uncertainty?

    In general I would say no. But we really need some context to be able to give you a helpfull answer.

    The uncertainty of a particle's position is .100 nm. So, I'm looking for the percentage of uncertainty in its momentum.

    U can find the uncertainty in momentum applying Heisenberg principle,but u need to specify the momentum itself,as the procentage is usually defined as the product of the uncertainty and 100 devided by the measured momentum.

    Where does that rule come from?

    Because by that definition,aren't delta p and p equal?
