Fetch the label from custom field label:

<apex:outputLabel value="{!$objecttype.account.fields.Acct_Recon_Full__c.label}"></apex:outputLabel>

If custom label is part of managed package, then we also need to use namespace for accessing custom label in our custom apex code which is not part of managed package. Lets say DemoLabel is part of managed package and managed package namespace is ‘myName’. Then we need to use following code to access DemoLabel in apex code.

1	String customLabelValue = System.Label.myName.DemoLabel;

To create Custom Label, click Your Name | Setup | App Setup | Create | Custom Labels. You only can add translation language for a custom label based on languages supported in Translation Workbench.

And this is the final formula, it is just $Label.Label_Name
