Infinite While Loop Help

[DarkCode91]

I've tried looking up a fix but I haven't been able to find anything. Entering the loop is fine and I can input the values I need too but when it goes back into the loop I am unable to input anymore values. I can't seem to figure the problem out and I don't see any errors in my code that would cause it to make me unable to input any values with cin >>. I tried to reset Weight_Test to 1 to make it restart the loop but it still wont let me input values. When I put Weight_Test = 0 at the end of the loop it will stop the loop. Thank you for your time!

#include <iostream>
using namespace std;

int main()
{

	double Weight_Test = 1, Weight, Conversion, Weight_Unit;

		while(Weight_Test != 0)
		{
			
			cout << "Enter weight value (0 to stop): ";
			cin >> Weight_Test;
			cout << "Was the weight value in o)unces or p)ounds? ";
			cin >> Weight_Unit;
			Weight = Weight_Test;
			if ('P')
			{
				Conversion = Weight * 0.062500;
				cout << Conversion << " ounces = " << Weight << " pounds" << endl;
			}
				else
			if ('O')
			{
				Conversion = Weight * 16.000;
				cout << Weight << " ounces = " << Conversion << " pounds" << endl;	
			}
			
			Weight_Test = 1;
		}

Line 15. You are reading a double. If you type a character, the std::cin will have fail-flag set. All following input will automatically fail, unless you clear the error and discard offending content from the stream.

Do you want a double or a char?


Conditions on lines 17 and 23 do not make sense. They are both true.

YES! That worked. I didn't notice I had it on a double. Silly me haha. Thanks so much! I'm also about to fix my if statements right now. I've been more worried about the infinite loop. Thanks again!
