Apparently a new study of the volume and average depth of the oceans. http://blog.taragana.com/science/2010/05/19/how-deep-is-the-ocean-13785/ http://news.softpedia.com/news/Oceans-Get-Their-Volume-and-Depth-Calculated-142449.shtml
The above articles use primarily metric data. Some other versions use various roundings and conversions. Even the metric articles combine large counting words (billion) with metric prefixes. Why not just use 1.332 Mm³, or use scientific notation, 1.332E18 m³? Average depth is 3.6822 km.
