Use the .223 Remington round, which is the civilian version (i.e. freedom variant) of the 5.56 NATO round, and is what’s generally used in the AR15.
I’ll allow the 9mm because it’s used by the FBI and many police departments, but a true patriot would use the .40 round, which is about the same size, just a little shorter, a little stockier, a little heavier, and a bit more gunpowder. So 98425 .40 rounds wide is one km, or round to 100k.
If by “freedom units” you mean football fields, that would be roughly 109,361.33 ff/s.
Most Americans could probably use metric easily if they just remember a meter is about 180 5.56 NATO rounds wide. A kilometer is 111,111 9mm rounds.
Easy.
Why did you use communist units?

Use imperial rounds, not communist metric rounds.
