What is an attonewton (aN)?

An attonewton is an SI unit of force equal to 10⁻¹⁸ newtons, used to represent extremely small forces at atomic and sub-atomic levels.

Why convert attonewtons to pound-force?

Conversion helps translate tiny atomic-scale forces into commonly understood Imperial units used in mechanical and aerospace applications.

Does this conversion assume gravity differences?

Yes, the pound-force unit assumes standard gravity conditions when defining force.
