Nice solution! I like this small footprint :-)

Sorry my english is not so good. Which part of the description you don't understand?

Sorry, i've forgot to test x,x4 / x,x6 problem. I've edited the kata so this solution fails.

I assumed that you would normally rounded that way.

I have now added a note due to multiple desire with respect to the liter / gallon - problem.

I don't think it is an issue mora a simplification. But i added a note ;-) So please comment by the "issue" below.

That was actually intended. The warrior must think about the difference between europe standards and us standards. I've edited my fauxpas with Array and Objects (thanks for your note) and added a Note for all wrriors about litre

Try it again. I think i've fixed the issue

Thank you for your response i would fix the test's

It's very nice kata. There are 2 possible solutionsways. That's very nice :-)

I love your idea. I would try to create a Kata ;-)
