A level teaspoon of sugar is roughly 5 grams, and 500 mg is about 1/10 (on tenth) of 5 grams. So 470 mg would be about one tenth of 1 teaspoon or slightly closer to 1/11.
But remember that a teaspoon is not a scientifically precise measurement. There is no sense to arguing about just what fraction of a teaspoonful 470 mg would be.
It depends on the density of the material being measured. Very dense material like uranium will occupy less space than less dense material like carbon so there is no universal answer to this question. You need to indicate what material is being measured.
