What are some key considerations when calculating and displaying humidity-related values in PHP scripts for weather data processing?

When calculating and displaying humidity-related values in PHP scripts for weather data processing, it is important to ensure that the values are formatted correctly and accurately represent the humidity level. Additionally, it is crucial to consider the units of measurement being used (e.g., percentage, grams per cubic meter) and to properly handle any conversions that may be necessary. Finally, displaying the humidity values in a clear and user-friendly manner can enhance the overall user experience.

// Example code snippet for calculating and displaying humidity values in PHP

// Assuming $humidity is the raw humidity value retrieved from weather data
$formatted_humidity = number_format($humidity, 2) . "%"; // Format humidity value with 2 decimal places and add percentage sign

echo "Current humidity level: " . $formatted_humidity; // Display the formatted humidity value
