Why is the currency converter not converting money into (k) = (thousand) or (M) = (million)?

SO when I reach $1000 in my idle game, i want to to turn into $1K, same with the millions. But there are no errors and it doesnt convert? here is the code. using UnityEngine; using System.Collections;

public class CurrencyConverter : MonoBehaviour {

 private static CurrencyConverter instance;
 public static CurrencyConverter Instance{
     get{
         
         return instance;
     }
 }
 
 void awake(){
     CreateIntance();
 }
 
 void CreateIntance(){
     if (instance == null) {
         instance = this;
     }
 }
 
 public string GetCurrencyIntoString(float valueToConvert, bool currencyPerSec, bool currencyPerClick){
     string converted;
     if (valueToConvert  >= 1000000) {
         converted = (valueToConvert / 1000000f).ToString ("F3") + " M";
     } else if  (valueToConvert >= 1000) {
         converted = (valueToConvert / 1000f).ToString ("F3") + " K";
     } else {
         converted = "" + valueToConvert;
     } 
     
     if (currencyPerClick == true) {
         converted = converted + " tpc";
         
     }

     return converted;
 }

}

IS there something wrong in the code? Plz reply with the best feedback as possible, thanks.
