The newborn blue whale calf weighs about 2.5 metric tons (2.8 short tons) and is around 7 metres (23 ft) in length.
A newborn sperm whale calf is about 13 feet (4 m) long and weighs about 1 ton (0.9 tonnes).
A whale normally weights upto 150 tons and mesures 30 meters.
The mass varies drastically. They can weigh up to 209 tons. On average they weigh between 100-150 tons. Females tend to grow a bit bigger.
Blue whales are difficult to weigh because of their size. Most blue whales killed by whalers were not weighed whole, but cut up into manageable pieces first
This varies drastically depending on the species. Blue whales can weigh upto 209 tons which is about 200,000kg. Dwarf Sperm whales can grow to 600 pounds which is 272 kilograms.
the mass of a blue whale is 390 g
Male: 8 tonsFemale: 4 tons
It would depend on the species

5.91 double decker traditional routemaster London buses would appear to be the equivelent to a blue whale. Assuming the laden weight of a routemaster to be 23000 kilo's, and a fully grown blue whale to be 136000 kilos.Answera blue whale is longer as three buses.

Blue whale. Nothing is bigger than a Blue whale it is the largest animal on the planet. The above answerer is being ignorant. Amphicoelias fragilimus potentially can have vastly more mass and legth than a blue whale.
You would have to know the mass and the volume of your blue whale in order to find the density, or have the average density of the whale given to you. If you have the mass and the volume, then you can find the density using the equation D=mv, where D= Density, m=mass, and v=volume. Or, you can Douglas Adams it and say 42.
A fully grown blue whale has a mass probably reaching over 181 tonnes (181000 kilos) and a length of about 30 metres.
A blue whale has a mass of over 100 tons.
