LCD Programming with Arduino
This is what I ended up with.

#include &lt;Wire.h&gt; 
#include &lt;LiquidCrystal_I2C.h&gt;
LiquidCrystal_I2C lcd(0x27,16,2);  

void setup() {}

void loop()
{ lcd.init();                      
lcd.backlight();

int VoltsInput = A0;
int VoltsRange = 0;
int VoltsPercent = 0;

VoltsRange = (5.0/1023.0) * analogRead(VoltsInput);
VoltsPercent = (((5.0/1023.0) * analogRead(VoltsInput)) / 5) * 100;

lcd.print(VoltsRange);
lcd.print("V    ");

lcd.print(VoltsPercent);
lcd.print("%");}
