    Please Help me with this (if) code

    I am practising the if code and decided to do a converter of different units of different types. It is not finished yet but I am running into a problem, when I select 2 then 9, 10, 11,12 it always starts with 8. It reads off 8 then goes 9... Help will be appreciated. Here is the code ...
    Code:
    #include <stdio.h>
    #include <conio.h>
    int main(void)
    {
      int Type_of_conversion;
      float fahrenheit;
      float celsius;
      int f_or_c;
      printf("Temperature......................1\n\n");
      printf("Mass.............................2\n\n");
      printf("Type The Corresponding Number To Select The Type of Conversion: ");
      scanf("%d" ,&Type_of_conversion);
      if (Type_of_conversion ==1)
        {
        printf("\n");
        printf("Fahrenheit to Celsius.......1\n");
        printf("Celsius to Fahrenheit.......2\n");
        printf("\n");
        printf("Type the corresponding number for the unit of conversion: ");
        scanf("%d" ,&f_or_c);
        if (f_or_c == 1) {
            printf("Enter the Temperature in Fahrenheit:  ");
            scanf("%f" ,&fahrenheit);
            celsius = (fahrenheit-32)*(5.0/9.0);
            printf("%f degrees celsius", celsius);
        }
        if (f_or_c == 2) {
            printf("Enter the Temperature in Celsius:  ");
            scanf("%f" ,&celsius);
            fahrenheit = celsius*(9.0/5.0) + 32;
            printf("%f degress fahrenheit", fahrenheit);
        }
       }
       if (Type_of_conversion ==2) {
        printf("                             \n");
        printf("Kilograms to Pounds.........1\n");
        printf("Pounds to Kilograms.........2\n");
        printf("Kilograms to Ounces.........3\n");
        printf("Ounces to Kilograms.........4\n");
        printf("Pounds to Ounces............5\n");
        printf("Ounces to Pounds............6\n");
        printf("Grams to Kilograms..........7\n");
        printf("Kilograms to Grams..........8\n");
        printf("Grams to Pounds.............9\n");
        printf("Pounds to Grams.............10\n");
        printf("Grams to Ounces.............11\n");
        printf("Ounces to Grams.............12\n");
        printf("                             \n");
        printf("Type the corresponding number for the unit of conversion: ");
        int type_of_mass;

    Look at line 98. Misplaced semi-colon.
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Sunshine, and read this, this, and this before posting again.

    do while loop... that way you can have a final menu item to exit the program

    Try reading your textbook, or any introductory material, about the "do while loop".
