Example 2: different formulas to convert celsius to fahrenheit

function fahrenheitToCelsius(fahrenheit) {
  return (((fahrenheit - 32) * 5) / 9).toFixed(1);
} // Using toFixed returns a decimal value

function celsiusToFahrenheit(celsius) {
  return ((9 * celsius) / 5 + 32).toFixed(1);
} // Better to multiply in this order for celsius
