                   There are so many beautiful and amazing animals all over the world! Unfortunately,
                   some  of them  are endangered.  It is  important  to  protect  these  animals  if we
                   want to save our planet, Earth. In India, some animals are also endangered, and
                   a few are even on the verge of extinction. A list of such animals is given below.

                      1.  Look at the standard lengths or heights (in m) and weights (in  kg) of some
                          of the endangered animals and express them in other units as directed.
