You're both upvoted. I'm going to try the Fibonacci version for a while.

(Though perhaps as is suggested with languages, it's better to start applying the new system directly, instead of performing a conversion step first.)

Yes! What is a meter? One Yard! 1km = 10 football fields (no end-zones)

I find that meters are better for thinking about walking measures, why does our system even have a yard? Think in units, metric is good. I learned this in American Public School. I was very lucky.
