Return to Question

So I recently started "coding" and I'm really really into the beginning and this is one of my first "projects". It is supposed to be SI converter where you can type value, its unit and the unit you want it to be converted.

Can you give me some opinions about the code and how can I improve? P.S I repeat I'm still beginner in programming so I don't know much.

I did some things to the code what about now?

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Program { class Program { static void Main() { decimal one = 1; decimal milli = 0.001m; decimal micro = 0.000001m; decimal nano = 0.000000001m; decimal pico = 0.000000000001m; decimal kilo = 1000; decimal mega = 1000000; decimal giga = 1000000000; decimal tera = 1000000000000; decimal answer; while (true) { Console.WriteLine("SI converter!\nPlease, enter value: "); decimal value = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("\nFactors: \n1.One \n2.Milli(m)\n3.Micro(µ)\n4.Nano(n)\n5.Pico(p)\n6.Kilo\n7.Mega\n8.Giga\n9.TeraEnter factor: "); decimal factor = int.Parse(Console.ReadLine()); switch (Convert.ToInt32(factor)) { case 1: factor = one; break; case 2: factor = milli; break; case 3: factor = micro; break; case 4: factor = nano; break; case 5: factor = pico; break; } Console.WriteLine("\nFactors: \n1.One \n2.Milli(m)\n3.Micro(µ)\n4.Nano(n)\n5.Pico(p)\nEnter the second factor: "); decimal factor2 = Convert.ToInt32(Console.ReadLine()); switch (Convert.ToInt32(factor2)) { case 1: factor2 = one; answer = factor * value; Console.WriteLine("The answer is "+ answer); break; case 2: factor2 = milli; break; case 3: factor2 = micro; break; case 4: factor2 = nano; break; case 5: factor2 = pico; break; } answer = value * factor / factor2; Console.WriteLine("The answer is : " + answer); Console.WriteLine("Go again?\nY / N"); char ans = char.Parse(Console.ReadLine()); if (ans == 'n') { break; } if (ans == 'y') { Console.Clear(); } } } } }
