There's also the hg-git Mercurial plugin with which it's possible to convert HG repos to Git repos.
Here's the relevant part from the readme (section "Usage"):
Note that hg-git only understands Mercurial bookmarks, not Mercurial branches!
(because it was designed to convert into both directions, and there's no Git equivalent to Mercurial's named branches - Git branches are more like Mercurial bookmarks)
If your Mercurial repository has named branches that you want to keep, you need to create a bookmark for each of them before the conversion.
I tried GitHub's importer (mentioned in the other answer) as well, but liked hg-git better because I have more control over the end result.
What I didn't like about the GitHub importer is that it creates commits with "strange" email adresses.
Even though the commits in the HG repos have the same email adress as my GitHub user, the importer still asks me to map the commits to an existing GitHub user.
And even though I select my own user and the commits in the GitHub UI look like they were made by my user, the actual adresses in the repo (when I clone it) look something like this:
With git-hg, you can create a text file with "mappings" from the existing HG committers to the desired Git committers.
Example from the link:
So if the HG repository had commits from committer
johnny
, they will automatically be changed toJohn Smith <jsmith@foo.com>
in the converted Git repository.I found https://github.com/frej/fast-export which correctly migrates Mercurial branches to Git branches (in contrast to hg-git which only works with Mercurial bookmarks).
Fast-export works on a local (copy of the) repo so it's not purely online. Fast-export has instructions how to create a new local Git repo and populate it.
In my case, I had left some multiple branch heads in Mercurial, giving this error:
I could use "hg strip 493" or do a merge to get rid of these heads.
I also had to fix the author fields of some commits, using an "authors file" and the -A switch to fast-export to map the ill-formatted author fields, as described in the README.
Afterwards fast-export accepted the repo.
You also need to create a new Bitbucket repository through the Bitbucket web interface.
Then push to Bitbucket. This example sets up using already configured SSH:
I've heard that this script works. Not sure if it converts branches.

The only way I found to convert a Mercurial repo to Git, while keeping all the branches, was to use GitHub's importer. This was also the easiest since it's all done online. Nothing local to install, no command line stuff.
Main idea
Use Github's importer to convert Bitbucket Mercurial repo to GitHub Git repo. Then import that back into Bitbucket.
The steps
In Bitbucket:
Rename the Mercurial repository that you want to convert (if you want the new Git repo to have the same name as your Mercurial repo did). You do this in Settings. For example, name it projectname_mercurial.
Grab the Clone URL of the repository. (On the repo's main page, click Clone and grab just the URL, like https://username@bitbucket.org/username/projectname )
In Github:
If you don't already have an account, create one https://github.com
Use the GitHub importer https://github.com/new/import
Set it to private. Public is default!
NOTE: You can add your password to the URL directly, which will then avoid the need to enter your credentials in the steps below (thanks to @keith-turkowski comment below). So change your bitbucket clone url by adding :password after username, like this: https://username:password@bitbucket.org/username/projectname
Begin Import in Github
WAIT! Do not close the page when it says that you can (We'll email you...). Wait for it to ask you for the repo credentials. This can take several minutes. Then enter the credentials. (Assuming it requires credentials.)
WAIT AGAIN! It's again going to ask for your repo credentials. At least it did for me, every time. (See note above on adding your password directly to URL so it does not ask you.)
Now you wait until it's done. You will get an email.
When it's done, grab the GitHub project URL. It's just the webpage URL when you are on the GitHub project page.
In Bitbucket:
Create a new repository using the "+" > Import > Repository menu option.
In Github:
Delete the imported project: Project's Settings tab > Delete this repository
