About this converter
Whale maximum weights run from 1,429 kg to 149,685 kg, which makes every species easy to compare. The Blue Whale tops out near 330,000 pounds, while the Beluga averages 3,150. That means one Blue equals more than 100 Belugas. Every figure on this page is a NOAA Fisheries species page maximum converted to kilograms at 1 pound to 0.45359237 kg. Tons on NOAA pages are US short tons of 2,000 pounds. The Beluga row is an average, not a max, and the table says so. Weights have no dollar conversion, so this page compares kilograms to kilograms.
How to use it
Pick two whales and a unit in the top row. The three boxes below stay linked: one holds a count of the first weight, one the matching count of the second, one the total in the chosen unit. Change any box and the other two update. Try 1 Blue Whale against Belugas to feel the full span, or the Fin against the Bowhead for second place.
The Fin at 72,575 kg is second to the Blue. The Bowhead at 90,718 outweighs the Right at 63,503. Gray and Sperm both land at 40,823 from 90,000 pounds, with the male Sperm max used. Humpback reads about 40 tons for 36,287. Orca at 9,979 is the largest dolphin family member here. Minke at 9,072 is the smallest baleen whale in North American waters. Narwhal uses the 3,530 pound top of its range for 1,601.
