For those of us in the U.S., 2.7 liters is about 2.8 quarts.

Thanks for following me. It brought me to your profile on Medium and then to this article.

This is news to me. I have been drinking 6 8-oz cups a day, which is what I was told by a nurse would be sufficient. Also news to me was that craving salt is a sign of dehydration. Seems counter-intuitive, but I'll take your word for it and the needed 2.7 liters as well. Thanks for educating me.
