How can rounding to two decimal places be implemented in a MySQL query for temperature conversion in PHP?

When converting temperatures in PHP and storing them in a MySQL database, it is common to want to round the result to two decimal places for accuracy. This can be achieved by using the `ROUND()` function in MySQL within the SQL query that inserts or updates the temperature value. 

// Assuming $temperature is the temperature value to be converted and stored in the database
$convertedTemp = ($temperature * 9/5) + 32; // Convert temperature to Fahrenheit
$roundedTemp = round($convertedTemp, 2); // Round to two decimal places

// MySQL query to insert or update the rounded temperature value in the database
$query = "INSERT INTO temperature_table (temperature) VALUES (ROUND($roundedTemp, 2))";
// Execute the query using your preferred method (e.g. mysqli_query or PDO)
