The ToMetric method is a static extension method in the SandboxSystemExtensions class. It converts an integer value into a human-readable metric string representation, using the specified number of decimal places. This is useful for displaying large numbers in a more compact and understandable format, such as converting 1000 to "1K".

To use the ToMetric method, call it on an integer value, passing the desired number of decimal places as the second argument. This method is particularly useful when you need to display large numbers in a more readable format.
