USGS provides batch file conversion scripts (USGS_Raster_Conversion_Scripts) to make it easier to convert The National Map raster staged products from current downloadable formats into other common formats. These scripts require either Geospatial Data Abstraction Library (GDAL) or Esri ArcGIS software for raster data file conversions. The documentation is in HTML and is under the 'How_To' folder. It includes procedures for getting GDAL from http://www.gisinternals.com and Esri based scripts that should work with ArcGIS 10.x.
