error invalid conversion from 'float*' to 'int' [-fpermissive]

Ok so, i'm trying to covnert some number into others via function. The vector "tempc" contains 7 celsius numbers. The type "tempf" will contain fahrenheit. But i get this error in the title "error invalid conversion from 'float*' to 'int' [-fpermissive]". I'm new to programming , so i'm kinda really newbie. Sorry for the code but it's in italian 

#include <iostream>
using namespace std;

//dichiarazione variabili e vettori
float tempc[7] = {23,25,22,19,18,20,16};
float tempf[7];
const int MAX_GRADI = 7;

//funzione conversione
int ConversioneInF ()
{
    for (int i=0;i<MAX_GRADI;i++)
        tempf[i]=(9/5)*tempc[i]+32; //C in F
    return tempf;

}

int main () 
{
    ConversioneInF();
    for (int i=0;i<MAX_GRADI;i++)
        cout<<"La temperatura in fahrenheit e' :"<<tempf[i]<<endl;

    return 0;
}

void ConversioneInF ()
{
    for (int i=0;i<MAX_GRADI;i++)
        tempf[i]=(9.0/5.0)*tempc[i]+32;
}

Anyway, tempf is global, you don't need to return it.

In your function ConversioneInf you are returning tempf. This is a float-array, which in c++ is a pointer to float (float*) This type cannot be converted to the specified return type int. As you are not using the return value, just change it to void:

void ConversioneInF ()
