In this tutorial, you will learn how to convert temperature from Celsius to Fahrenheit and vice versa. Here is an example where we have created three functions celcius(), fahrenheit() and display table. It prints the chart in tabular format and shows the conversion of the Fahrenheit equivalents of all Celsius temperatures from 0 to 100 degrees in 4 degree intervals and the Celsius equivalents of all Fahrenheit temperatures from 32 to 212 degrees in 10 degree intervals.
Example
import java.util.*;
import java.text.*;
class Degrees
{
public static double fahrenheit(int temp) {
return (1.8 * temp) + 32;
}
public static double celsius(int temp) {
return (temp - 32) / 1.8;
}
public static void displayTable(){
DecimalFormat df=new DecimalFormat("##.#");
System.out.println("Celcius (C) Fahrenheit (F)");
for(int i=0;i<=100;i+=4){
System.out.println(i+"\t | "+df.format(fahrenheit(i)));
}
System.out.println("Fahrenheit (F) Celcius (C) ");
for(int i=32;i<=212;i+=10){
System.out.println(i+"\t | "+df.format(celsius(i)));
}
}
public static void main(String[] args)
{
displayTable();
}
}
Output:
Celcius (C) Fahrenheit (F) 0 | 32 4 | 39.2 8 | 46.4 12 | 53.6 16 | 60.8 20 | 68 24 | 75.2 28 | 82.4 32 | 89.6 36 | 96.8 40 | 104 44 | 111.2 48 | 118.4 52 | 125.6 56 | 132.8 60 | 140 64 | 147.2 68 | 154.4 72 | 161.6 76 | 168.8 80 | 176 84 | 183.2 88 | 190.4 92 | 197.6 96 | 204.8 100 | 212 Fahrenheit (F) Celcius (C) 32 | 0 42 | 5.6 52 | 11.1 62 | 16.7 72 | 22.2 82 | 27.8 92 | 33.3 102 | 38.9 112 | 44.4 122 | 50 132 | 55.6 142 | 61.1 152 | 66.7 162 | 72.2 172 | 77.8 182 | 83.3 192 | 88.9 202 | 94.4 212 | 100
