How big is an iceberg underwater?
Q: How much of an iceberg is below water? A: Almost 90% of an iceberg is under water, hence the phrase “tip of the iceberg.” Its maximum width under water is 20-30% larger than you can see at the surface. The average depth, or draught of an iceberg, is slightly less than its apparent length above water.
