What are you even trying to say here? Yeah, in real-life use we use “close enough”. I don’t need to know that it’s 1,546 metres to the nearest supermarket. 1.5 km is close enough.
But nobody is suggesting it because it’s “so accurate”. Any system can be accurate, depending on how many sig figs you use. The advantage of metric is on how easy it is to convert between different scales. Use millimetres, metres, or kilometres for the appropriate case, depending on the need you have for precision. And just move the decimal point if you decide you don’t need as much precision…or need more. In archaic measurements, you can’t do that. If you’ve got 342 feet and decide you actually only need to be accurate to the chain, you have to memorise the arbitrary number of 3 feet to a yard, and 22 yards to a chain, and divide 342 by those numbers, to arrive at 5.2 chains.

Aren’t chains only used by railworkers?
