About this converter
Maximum sounded depths run 505 to 1,642 meters across rift, glacial and caldera lakes. Toba sits at 505, Quesnel at 511, Hornindalsvatnet at 514 as Europe deepest, General Carrera at 586, Matano at 590, Crater at 594 as USA deepest, Great Slave at 614 as North America deepest, Issyk-Kul at 668, Malawi at 706, O Higgins at 836 as Americas deepest, Caspian at 1,025, Tanganyika at 1,470 and Baikal at 1,642. Vostok subglacial estimates near 900 to 1,000 stay out since ice buries direct soundings. Tanganyika splits 1,470 and 1,471 by survey rounding.
How to use it
Pick two lakes and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try 1 Baikal against Toba to see the three point two to one gap. Switch to feet for imperial maps.
Caspian counts as an endorheic salt lake with no ocean outlet despite the sea name. Sarez ties Toba at 505 as landslide dammed and stays out to keep one anchor. Issyk-Kul cites 665 to 668 across sources with 668 most cited. Remote old soundings vary a few meters per basin.
