(First off, I believe module names must start with an uppercase
letter, i.e. call it MetricCalc.)
It depends on what you mean more exactly.
You can use `ghci` to load the source file directly:
~~~
Prelude> :l MetricCalc.hs
*MetricCalc>
~~~
If you use Cabal you can compile it and place it in a library which
you subsequently can install, so that you can use it from other
projects you work on.

Excellent! I can recommend reading the ghc docs[1], they are good and
very readable. Then peruse Hackage to find examples of how things
work.
