## Functions

# Nested Functions

This is a follow up to Writing Functions.

Measuring things using the metric system is great for us scientists, but when
you call your grandmother this weekend (*you do call your grandmother every
weekend don’t you?*) you’d like to tell her that you’re taking this awesome
class where you learned how to program a computer to calculate how much
dinosaurs weigh (*if you phrase it like this she’ll have something really cool
to brag about to her friends*), and that you calculated the weight of a
Stegosaurus (*no need to scare grandma by talking about the totally awesome, and
really scary, Spinosaurus*). The problem is that your grandmother doesn’t really
know what a kilogram is, she wants to know what it weighed in pounds. So, hook
your grandmother up and write a function that converts kilograms into pounds
(there are 2.205 pounds in a kilogram). Use that function along with your
dinosaur mass function to estimate the weight, in pounds, of a 12 m long
Stegosaurus (*12 m is about as big as they come and we want grandma’s story to
be as wild as possible*). In *Stegosauria*, `a`

has been estimated as `10.95`

and `b`

has been estimated as `2.64`

(Seebacher 2001).
