java - 如何将英尺转换为米？

Question

import java.util.Scanner;

public class feetToMeters {
    public static void main (String [] args) {
        final double feetToMeters = 0.305;
        Scanner input = new Scanner (System.in);

        System.out.println ("Enter a value for feet: ");
        double value = input.nextDouble();

        System.out.println (value + " feet is " + " meters " + meters);
    }
}

我还需要添加什么才能将英尺转换为米？谢谢！

Answer 1

您就在那里获得了转化价值，0.305. 这个数字表示多少米等于 1英尺，所以要计算多少米等于value英尺数，我们只需乘以：

double meters = value * feetToMeters;

Answer 2

With your variable names, you would need:

double meters = value * feetToMeters;

Answer 3

import java.util.Scanner;

public class feetToMeters {

  public static void main (String [] args) {   
  Scanner input = new Scanner (System.in);

  System.out.println ("Enter a value for feet: ");
  double value = input.nextDouble();
  double meters = value/3.2808;
  System.out.println (value + " feet is " + meters + " meters ");

    }
}
