온도에는 섭씨, 화씨 및 켈빈의 세 가지 측정 단위가 있습니다. 이 튜토리얼은 모든 유형의 측정 단위에 대해 온도를 한 단위에서 다른 단위로 변환하는 방법을 보여줍니다.
Java에서 온도 변환기 만들기
단위에 따라 한 단위에서 다른 단위로의 변환에는 6가지 유형이 있습니다. 각 변환에는 다른 공식이 있습니다.
아래 표는 온도 변환에 대한 모든 공식을 보여줍니다.
| 변환 | 공식 |
|---|---|
| 섭씨 받는-사람 화씨 | °F = (°C × 9/5) + 32 |
| 섭씨 에서 켈빈으로 | °K = °C + 273.15 |
| 화씨 받는-사람 섭씨 | °C = (°F − 32) × 5/9 |
| 화씨에서 켈빈으로 | °K = (°F − 32) × 5/9 + 273.15 |
| 켈빈에서 섭씨로 | °C = °K − 273.15 |
| 켈빈에서 화씨로 | °F = (°K − 273.15) × 9/5 + 32 |
이 6가지 공식을 Java로 구현하여 온도를 변환할 수 있습니다. 우리는 범용 온도 변환기를 만들기 위해 하나의 프로그램에서 6가지 공식을 모두 구현했습니다.
예를 참조하십시오.

public class Temprature_Converter {
static Scanner sc = new Scanner(System.in); // Scanner Class

}
// Driver Method

System.out.println("\nEnter Your Temperature Choice Number: ");
int Temprature_Choice = sc.nextInt();
double Choice_Number = 0;
switch (Temprature_Choice) {
case 1:
Choice_Number = Input_Temperature("Celcius");

case 2:

case 7:

}
} while (true);
}
}
위의 코드는 사용자로부터 선택 숫자로 입력을 받은 다음 변환할 온도를 받은 다음 선택에 따라 변환합니다.
