Going to be starting up a program soon that will run about 8 weeks long that is requiring me to drink 1 liter of water per 30 lbs of weight. My main goal is to consume 2 gallons of water per day, but I know some days that will just not be possible. Used to drink 1 full gallon every day no problem, but 2 will be tough. So anyway the minimum is 1 liter per 30 lbs so how many liters is in a gallon? Thanks.
