50-100 feet - the approximate height above water of the iceberg that sank Titanic, as recounted by survivors.
200-400 feet - the estimated length of the iceberg.
10% - the percentage of the total mass of an iceberg that is typically visible above water, as the sheer weight of an iceberg means that most of the bulk is underwater.

1 mile - the likely original length of the Titanic iceberg, but after 12 months scraping and rebounding along a 40 mile length of fjord, by the time it reached the Atlantic it would already have reduced to around half its original length.
1 billion tons - the amount of sea water that the iceberg would have displaced at its original size.
2 weeks - the approximate length of time after the Titanic struck before the iceberg would have finally disappeared, melted away by the warm waters of the gulf stream.
