Using kilometers to measure a whale is totally pointless. Blue whales typically grow to 85ft but they can grow to 100ft. Let take 100ft, convert that to km is 0.03048 kilometers. Pointless to measure a whale in km.
The width can varies and is different for individuals of a species. In terms of length, is is 82 feet for largest species of whale on average. That would be a blue whale. They can measure upwards to 110 feet.
This depends on the subspecies of right whale. Southern right whale can measure to 59 feet. Northern right whale can measure to 60 feet.
The average length of a blue whale is to 82ft for males. Female blue whales can measure 85ft. The largest whale measured at 98ft.
No whale measures at that 13000 cm. 13000 cm is equal to over 400 feet. The largest known whale measure to 110 feet at most.
Any sensibly sized unit of length, such as feet, yards or metres.
A killer whale is much bigger than beluga. A beluga whale is about 4-6.1 metres in length whereas an adult male killer whale can measure from 6-9.1 metres. :)
A good measure would be Tons (2,000 pounds)
The length of a blue whale can be up to 30ft. So 30ft is equivalent to 9800cm at most roughly.
The length of a adult is around 50ft. Newborns measure to around 15 feet. They have known to grow to 60 feet.
I would measure it with a ruler.
a maximum length of a whale is 900 metres
the average length for an adult whale shark would be roughly around 13 metres
