Great, glad to be of help :)

Ok, good to know you're still working on the project! I'll clone that
repo and continue from there.

Thanks, it would be great to get metric units for us here in Europe :)

I have some experience with C, and believe I will be able to implement 
it. I was thinking of writing a couple of functions for distance, 
altitude, speed etc.

My first suggestion would be something like
const char *format_distance(struct state*state, const char *format, 
float dist);

The format string would be something like "%.2f %s", passed directly to 
snprintf(). This solution would give us some flexibility regarding 
formatting of values (most notably, number of digits I guess) and at the 
same time minimize the noise of dealing with two unit systems.

I guess will also could do this compile time, but I believe it will be 
easier for users if it's a config option.

What do you think, any thoughts?
