What does this phrase mean in french "isn't it so"?

Question

and this one 'to be correct"

Answer 1

A context would have helped a lot!!

"isn't it so"?  = n'est-ce pas? n'en est-il pas ainsi?

'to be correct" = pour être juste

But really I can't say without a precise sentence and context

Edit : "how is the weather?" = quel temps fait-il

Answer 2

usually it would be either "non" or "oui", like "c'est bon oui?"

Answer 3

Isn't it so, is another term meaning isn't this correct ? to be correct is another term for: if asked who is the president of the United States ? "to be correct" would be just to answer yes.

Answer 4

"isn't it so" : "n'est-ce pas"

"to be correct" : depending on the context "être correct" or the adverb "correctement".

Answer 5

isn't it so could be translated to "n'est-ce pas" or just "non"

to be correct "être exact"

how is the weather is "quel temps fait-il"

Answer 6

Another way :

C'est pas vrai?

Pour être exact, juste, correct. Depends on context.
