I enjoyed looking at the page with the alien being shown metric measures and would love show it to the children I teach. However, the spelling of litre in english is different from the US spelling - liter. As I wouldn't want to confuse some of the young children with spelling differences (they have enough just learning the maths!) would it be possible to do an english conversion just as there is with the US standard on the page.:)
This is a big problem for me. I get visitors from all over the world and so never know quite what to do about spelling.

Perhaps you underestimating your young children. Why not explain a little multicultural spelling to them.
If it ain't broke, fix it until it is.
No great discovery was ever made without a bold guess.
