Body weight (lb) divide by 2 seems to be the consensus general number of ounces I've seen from people like Dr Rhonda Patrick. And the more physically active you are, the more you should drink.

Eg: A 200lb person should drink 100oz+ of water a day.

In metric units: a 90kg person should drink about 3L of water a day.

Thank you for SI units. Some of us not living in the great country run by the universal moron understand this now better.
