Buoyant force of air negligible??

Why are we justified in assuming that the buoyant force on an object in air is generally negligible. Can you please explain using some example equations?

Many thanks.

Depends on the weight of the object and how accurate you need to be. Why not calculate the buoyant force on something and compare it to that something's weight.
