sorry about that, that was an error, I usually only mean to implement that before larger javascript scripts. here is the correct code:

// A function that converts Fahrenheit to Celsius
function fahrenheitToCelsius(fahrenheit) {
  // Use the formula C = (F - 32) * 5/9
  let celsius = (fahrenheit - 32) * 5/9;
  // Return the result
  return celsius;
}

// A function that converts Celsius to Fahrenheit
function celsiusToFahrenheit(celsius) {
  // Use the formula F = C * 9/5 + 32
  let fahrenheit = celsius * 9/5 + 32;
  // Return the result
  return fahrenheit;
}
