To anyone
have this Celsius to Fahrenheit program but when I enter a number 10 in the textbox it gives me 42 instead of 50
here is the formula to use for the program code.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace CelsiusandFahrenheitconverter
public partial class Form1 : Form
public Form1()

private void button1_Click(object sender, EventArgs e)
double celsius,tempconversion,fahrenheit;

celsius = double.Parse(textBox1.Text);
tempconversion = celsius*(9 / 5) + 32;
fahrenheit = tempconversion;
textBox2.Text = fahrenheit.ToString();
