Hi there @mutwakil96.

Your code mostly works fine. The only thing I noticed was that the check for using UK measurements instead of US wasn’t quite right. I updated it as follows, and it was fine:

if(document.getElementById("uk").checked) {
  let weight = Math.round(300 * 0.071428571428571) + " stone";
  let temperature =  Math.round((94 - 32) * 5/9) + " centigrade";
  newStory = newStory.replace("94 fahrenheit", temperature);
  newStory = newStory.replace("300 pounds", weight);
}
