从所有温度到一个温度

Question

我如何将此程序“从转换所有温度”更改为转换“我想要的温度”

import java.util.Scanner;


public class Suhu {

    static double suhuawal;
    static double suhuakhir;

    static double CelToFah(double suhuawal) {
        double cf;
        cf = ((suhuawal*1.8)+32);
        return cf;
    }

    static double CelToRem(double suhuawal) {
        double cr;
        cr = (suhuawal*0.8);
        return cr;
    }

    static double CelToKel(double suhuawal) {
        double ck;
        ck = suhuawal+273.15;
        return ck;
    } 

    public static void main(String[] args) {
        double x;
        Scanner in = new Scanner(System.in);
        System.out.print("Masukkan suhu awal: ");
        x = in.nextDouble();
        suhuakhir = CelToFah(x);
        System.out.println("Suhu Akhir Fahrenheit: "+suhuakhir);
        suhuakhir = CelToRem(x);
        System.out.println("Suhu Akhir Reamur: "+suhuakhir);
        suhuakhir = CelToKel(x);
        System.out.println("Suhu Akhir Kelvin: "+suhuakhir); 
    }

}

请不要更改身体结构，只需添加方法或其他可以帮助我的方法

        chosen=in.nextInt();
        switch (chosen) {
  case 1:

  default:

if(-1==chosen)System.out.print("Wrong choice! ");
else

    }
