程序将厘米转换成像素

给定一个整数厘米(代表以厘米为单位的长度)，任务是将其转换为以像素为单位的等效值。

例子：

Input: centimeter = 10
Output: pixels = 377.95

Input : centimeter = 5.5
Output : pixels = 207.87

方法：可以根据以下数学关系来解决问题：

1 inch = 96 px

1 inch = 2.54 cm

Therefore, 2.54 cm = 96 px
=> 1 cm = ( 96 / 2.54 ) px
=> N cm = ( ( N * 96) / 2.54 ) px

下面是上述方法的实现：

C++

// C++ program to convert centimeter to pixels
#include 
using namespace std;
  
// Function to convert
// centimeters to pixels
void Conversion(double centi)
{
  
    double pixels = (96 * centi) / 2.54;
    cout << fixed << setprecision(2) << pixels;
}
  
// Driver Code
int main()
{
  
    double centi = 15;
    Conversion(centi);
    return 0;
}

Java

// Java program to convert
// centimeter to pixels
  
import java.io.*;
  
class GFG {
  
    // Function to convert
    // centimeters to pixels
    static double Conversion(double centi)
    {
        double pixels = (96 * centi) / 2.54;
        System.out.println(pixels);
        return 0;
    }
  
    // Driver Code
    public static void main(String args[])
    {
        int centi = 15;
        Conversion(centi);
    }
}

Python3

# Python program to convert
# centimeters to pixels 
  
# Function to convert
# centimeters to pixels 
def Conversion(centi):
  
    pixels = ( 96 * centi)/2.54 
    print ( round(pixels, 2)) 
# Driver Code 
centi = 15
Conversion(centi)

C#

// C# program to convert
// centimeter to pixels
using System;
  
class GFG {
  
    // Function to convert
    // centimeter to pixels
    static double Conversion(double centi)
    {
        double pixels = (96 * centi) / 2.54;
        Console.WriteLine(pixels);
        return 0;
    }
  
    // Driver Code
    public static void Main()
    {
        double centi = 15;
        Conversion(centi);
    }
}

输出：

566.93
