How do you measure a whales weight?
Dead whales, stranded and decaying on beaches, can sometimes be weighed. But weighing a live whale is nearly impossible. Or, at least, it was impossible. Marine scientists have developed an innovative way to accurately estimate the heft of free-living whales by using drones to capture aerial footage of cetacean bodies.
Which unit would be best to use to measure the length of a whale?
Now we know that 1 inch is 2.54 cm hence we will convert the length from inches to centimeters by multiplying 2.54. Hence we have the length of whale in centimeters.
What is the normal weight of a whale?
In the Northern Hemisphere, males weigh an average 100 tonnes (220,000 lb) and females 112 tonnes (247,000 lb). Eastern North Pacific blue whale males average 88.5 tonnes (195,000 lb) and females 100 tonnes (220,000 lb). Antarctic males average 112 tonnes (247,000 lb) and females 130 tonnes (290,000 lb).
How do they know how much blue whales weigh?
130 000 – 150 000 kgAdult

How would you measure a whale?
The Volunteer Reference Manual published by the Quebec Marine Mammal Emergency Response Network explains that “[t]he measurement is taken from the tip of the upper jaw to the notch of the tail. One must not follow the curve of the body, but rather take a straight-line measurement.”
Do whales scale?
Whales even have a little bit of hair on their smooth skin, usually on the top of their head. Fish have scales. So whales are indeed mammals and not fish!
What unit would be best to measure the length of a boat?
In science classes, and anywhere outside of the United States, length is measured with the Metric System. The most common units that we use to measure length in the metric system are the millimeter, centimeter, meter, and kilometer. The millimeter is the smallest commonly used unit in the metric system.
Which unit would be best to measure the length of a swimming pool?
meters
To describe the length of an Olympic-sized swimming pool, a scientist would use meters (m). A meter is the basic SI unit of length. Other SI units of length are larger or smaller than the meter by multiples of 10. For example, if you divide 1 m into 1000 parts, each part equals 1 millimeter (mm).

How many grams does a whale weigh?
Blue whales weigh between 105,000,000 grams. The largest mammal to have ever lived, blue whales feed almost exclusively on krill — tiny invertebrates weighing about 1 gram each. Click here to see how other things compare to 2,730,000,000 grams…
How do scientists measure blue whales?
For whale scientists, this is a big problem. The solution colleagues and I came up with was to use a technique called photogrammetry – where the body size of the whales was measured from aerial photographs taken by drones. We applied this technique to southern right whales in Península Valdés in Argentina.
Which unit would be best to measure a river?
Most countries measure the length of rivers in kilometres, but some still use miles.
How do you measure the length of a whale?
There were 2 ways a whale was measured. One way is to physically measure by capturing it and measuring it. Another common way is to take a aerial photo of it and measure it by scaling it to the length of area that it was taken. Wiki User
How big is the largest whale in the world?
No whale measures at that length. 13000 cm is equal to over 400 feet. The largest known whale measure to 110 feet at most. Which length of measurment would you use to measure the length of a blue whale?
Is it possible to weigh a right whale?
Until now it has only been possible to weigh whales once they have washed up dead on beaches. Now scientists have solved the conundrum, with the help of aerial photographs taken by drones. Their model accurately calculated the body volume and mass of wild southern right whales.
How big is the average size of a blue whale?
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. What is the length of a right whale? This depends on the subspecies of right whale. Southern right whale can measure to 59 feet.
