Daily Fluid intake requirement

So How Much Water do you Really Need?

The most common advice is 2-3 liters of fluids, but no one ever told you the precise quantity.

You’re probably thinking, does a precise quantity exist?

Yes and it’s varies for each person.

The good news is… it’s easy to calculate.

I’m about to show you exactly how much fluid you need to consume everyday.


Before I show you how to calculate your fluid intake requirment I need to clarify something.

Many people assume fluid refers to water.

Water is an awesome drink, but it’s not the only fluid you can drink.

Why didn’t anyone tell you this before?

Great question.

Not sure, but it could be they just wanted to give you flexibility.

Nevertheless, some doctors from health.com have provided an equation to calculate the exact amount of fluids you should drink.

How do you calculate it?

Your weight in pounds divided by two. Now drink that amount in ounces.

Here’s an example:

Let’s say you weigh 180 pounds.

Divided by two = 90

That means you should drink 90 ounces a day.

You may want to convert to Liters.

So that’s 2.55718 Liters

Approx. = 2.6 Liters or 2600 ml

What’s that in glasses?

The average glass of water contains 250 ml.

That means you get the total amount in ml and divide that by the glass size (250 ml)

So, according to our example it would be this:

2600 / 250 = 10.4 glasses of water

To be on the safe side let’s say 11 glasses of water?

Resources to Convert

If you don’t know how to convert ounces to liters or kilograms to pounds then just head over to google and type:
