look at your float remeber what gets promoted and demoted give you a hint change one of your variables you declared

[Boxbird]

1.
float cent=x*2.54; //1cm=2.54 inch so multipling is conversion

Should be :
float cent = x * 2.54f;

2.
float inch=x*0.393701;//1 inch= 0.393701 cm so multipling with that is conversion

Should be :
float inch = x * 0.393701f;

Do I need to change the float I still get a error?

[Boxbird]

Do I need to change the float I still get a error?

What do you mean? This is the solution.

Here is another program if you can help me please.
