The Math of Water

For those of you trying to increase your water intake for each day what goals are you trying to meet? I personally like the gallon a day goal and would like to one day up it to two gallons a day but I am not holding my breath on that.

So how do you know if you’re getting a gallon a day? Easy. Math. I know, math is everywhere and in everything it would seem but this one is easy. If you cook, bake or do any of those things you already know a little something about measuring.

8 ounces = 1/2 gallon. So if you want to do a gallon you will need to do twice the amount in ounces–16 ounces for 1 gallon. (Thanks to the Betty Crocker cookbook for verifying that bit of math on the 1/2 gallon for me.)

So the next question is how many ounces are in the cup/glass you are using for your water. For me I use a glass that has 1 1/2 cups of water in it. Math again, 1 1/2 cup + 1 1/2 cup = 3 cups. (If you don’t know how much your cup/glass holds use a measuring cup to pour water into the glass and find out.)

So how do you keep up with the cups drank? That’s up to you but there are two ways that I can think of and both will depend on your memory. You can put down a mark on paper for every glass…you’ll need to remember to do this with every glass and then remember to do the math based on the ounces in each glass.


You could  write down the numbers 1-16 on the calendar or paper and scratch them off with each glass of water you pour (you’ll have to drink it before pouring another in the same glass).

If you are using a glass that holds 1.5 cups of water then 1 glass+1 glass will = 3 (1.5+1.5=3… in case you missed the math on the 1.5 cups in 1 glass thing.)

It’s really not complicated and kind of comes down to memory if you are going to try to document how much water you are drinking a day. A simpler method is to use a container that holds 1 gallon of water and finish the entire container before filling it up. This works if you don’t have somebody in the house who will gladly take your container and start drinking out of it.

And of course if you don’t care about your water intake then you don’t need to do any of this…just make sure you drink plenty of water to keep your body, skin, and health on the upward track to good instead of the downward track to dehydrated.

Stay Healthy
