程序将Pixels转换为rem和em

给定一个整数像素，以像素为单位表示框的宽度，任务是将像素转换为以rem和em单位度量的等效值。

例子：

Input: pixel = 45
Output: em = 2.812500, rem = 2.812500

Input: pixel = 160
Output: em = 10, rem = 10

方法：可以根据以下数学关系来解决问题：

For modern browsers,

• 1 rem = 16 px
  Therefore, 1px = 0.0625 rem
• 1 em = 16 px
  Therefore, 1 px = 0.0625 em

请按照以下步骤解决问题：

• 通过将像素乘以0.0625来计算像素的rem和em中的等效值。
• 以rem和em为单位打印等效的像素值。

下面是上述方法的实现：

C++

// C++ program to convert
// pixels to rem and em
#include 
using namespace std;
  
// Function to convert
// pixels to rem and em
void Conversion(double pixels)
{
  
    double rem = 0.0625 * pixels;
    double em = 0.0625 * pixels;
  
    cout << fixed << setprecision(6)
         << "The value in em is " << em << endl;
  
    cout << fixed << setprecision(6)
         << "The value in rem is " << rem << endl;
}
  
// Driver Code
int main()
{
    // Input
    double PX = 45;
    Conversion(PX);
    return 0;
}

Java

// Java program to convert pixel to rem and em
  
import java.io.*;
  
class GFG {
  
    // Function to convert pixel to rem and em
    static double Conversion(double pixel)
    {
        double rem = 0.0625 * pixel;
        double em = 0.0625 * pixel;
        System.out.println("The value in rem is " + rem);
        System.out.println("The value in em is " + em);
        return 0;
    }
  
    // Driver Code
    public static void main(String args[])
    {
        double pixels = 45;
        Conversion(pixels);
    }
}

Python

# Python program to convert pixel to rem and em
  
# Function to convert pixel to rem and em
  
  
def Conversion(pixel):
    rem = 0.0625 * pixel
    em = 0.0625 * pixel
    print "The value in em is", round(em, 2)
    print "The value in rem is", round(rem, 2)
  
  
# Driver Code
pixel = 45
Conversion(pixel)

C#

// C# program to convert pixel to rem and em
using System;
  
class GFG {
  
    // Function to convert pixel to rem and em
    static double Conversion(double pixel)
    {
        double rem = 0.0625 * pixel;
        double em = 0.0625 * pixel;
        Console.WriteLine("The value in em is " + em);
        Console.WriteLine("The value in rem is " + rem);
  
        return 0;
    }
  
    // Driver Code
    public static void Main()
    {
        double pixel = 45;
        Conversion(pixel);
    }
}

输出：

The value in em is 2.812500
The value in rem is 2.812500
