To be called a rope it needs to be more than 1 inch in circumference.

A long thin piece of material that cannot be reduced in width without physically breaking it is called a fibre; steel wire is a good example, uncomposited carbon fibre another, solid nylon fishing line a third.
If you take two or more fibres and simply twist them together to form a thicker, stronger piece of material this called a strand; pre-stressed concrete (PSC) steel strand is a good example where 6 wires are wrapped round a slightly thicker core (king) wire. In a gardening context a thin strand would be called twine.
If you take two or more strands and twist them together to obtain a thicker, stronger piece of material this is called a rope.
In other words it not about size or thickness it's about construction. Old fashioned string is a special case of a thin rope. Polypropylene 'string' is composed of fibres simply twisted together and is, therefore, strand or twine.

The strongest string or wire thats really thin is fishing wire, that can hold alot of pressure. Applying more strands and twisting will strengthen it and probally be the best darn rope I can think of.

Good question! I suppose if it's strong enough to hold a person or a boat or whatever then it's a "rope"!

it depends on the purpose really
you wouldnt use rope to bundle a parcel up now
and on the other hand you wouldnt use string to go climbing with either
