With all the different metrics circling around today, it can be quite a challenge to easily know all of them well enough to convert between them on the fly. Health experts recommend that you drink 2 liters of water a day to remain properly hydrated. However, despite knowing how many liters this is, it can be tricky to know how many ounces or imperial fluid ounces this is. So, how much is 2 liters of water, actually?

How Many Bottles Of Water Are Two Liters?

In the US, the standard size of a water bottle is 16.9 fl oz. This is equivalent to 500 milliliters (ml) which is half a liter.

I am sure you do not need this pointed out, yet to reach your daily target of 2 liters of water – you will need to drink 4 water bottles of this size. The entire bottle needs to be filled and drank otherwise you will be running short.

Bottled water is easy to buy in bulk which can help you have more motivation to drink it as some people struggle with this. It is also fresh water and can be incredibly refreshing.

Water Measurements

While it may be tricky to convert liters to fluid ounces, it is surprisingly easier than you think once you get the base value of their conversion rate.

A single liter is equivalent to 33.814 fluid ounces (fl oz). This means that for every liter you have to, or want to, drink – just multiply it by 34 (it is generally safe to round up in this instance).

So, for 2 liters of water, you are looking at roughly 68 fluid ounces.

This might seem like a lot but it is important to remember that you have 24 hours to do this and it is only a recommendation. Health experts cannot define the perfect amount of how much water each person needs to drink.

To do this easier, it can be beneficial to buy a water bottle that can hold a liter in it. Some water bottles will also have notes on them next to marking to show how much you should be drinking throughout the day.

A highly recommended way to get your 2 liters of water a day is to drink 8 glasses of water throughout the day. Ensuring your glasses are roughly 8 ounces in capacity will get you almost perfectly hydrated. It is surprisingly easy to prevent dehydration if you break the water consumption down into smaller, and more manageable, doses.

Men and women have different recommended amounts for the water they should be drinking, although everything above is valid as it is better to drink too much than not enough.

One study says that men should drink 125 fluid ounces of water a day. When calculating how many fluid ounces should a woman drink, they came up with the number 90. This is quite a lot less than the man’s intake. Another calculation was that everyone should drink half of their body weight in fluid ounces. So if you weigh 160 pounds, you should be drinking 80 ounces a day.

It is important to note that if you are working out or exerting yourself more than usual, you should equally up your consumption. This goes twice for hot days as it is easy to become dehydrated without realizing it when the weather is hot.

Why is Drinking Water So Good For Us?

It is always said that water is incredibly healthy for us to drink in abundance.

There are many benefits to drinking water and some of them can go quite unnoticed. These benefits are not guaranteed to take effect for every person as all of our bodies and metabolisms are different, but there are strong links to the increased consumption of water and these health benefits listed.

Best Physical Performance

When physically exerting yourself, you can start to sweat quite a lot. Sweat is a natural bodily response to being overworked or overheated in order to cool us down. It also happens to take quite a bit of moisture from our bodies as sweat has to be created.

Losing moisture content in our bodies can have bad effects on how we feel and these become noticeable even after the loss of 2% moisture. The less moisture content you have, the more fatigue you will endure from things like working out or exerting yourself. Working out will also seem physically and mentally more difficult than it normally is.

The muscles are mostly water, like the rest of our bodies, so it makes complete sense that we have to keep ourselves hydrated if we are going to use them.

More Energy and Higher Brain Function

Our mind and how healthy it really depends on hydration. It is so easy to forget how important it is to remain hydrated all the time.

If you lose 1-3% of body weight from moisture loss, you will be surprised at the effects it has on brain function and mood. Not only is brain function affected, but this lack of hydration is also known to cause anxiety in a lot of people when even the slightest bit (1-3%) of fluid is lost.

This amount of fluid can be lost easily throughout the day by doing basic things such as walking or jogging, so it is even more of a risk in the summer when it is incredibly hot.

The amount of water lost throughout the day by completing normal tasks such as walking and shopping is quite surprising, so when it is summer and the weather is hot and you are sweating, you really want to make sure you get enough water. Drinking eight ounces every hour or two is a great way to get how much water you want to drink.

Prevent and Treat Headaches

Hydration and headaches are more closely related than a lot of people assume. Some individuals can experience headaches or migraines when they are dehydrated. This shows that a headache is a sign of dehydration.

For those people who get headaches naturally quite often, water and hydration are known to relieve the pain of these frequent headaches. A lot of studies have been done with results showing that a lot of people in a test group reported feeling better and getting fewer headaches thanks to drinking more water. However, not everyone is in agreement as there have not been enough high-quality studies on this to produce the concrete results wanted.

Relieves Constipation

Constipation is one of those things that a lot of people will experience, and it is never pleasant. While there are many treatments for such a problem, drinking water and remaining hydrated are one of the first ideas you should have.

Remaining hydrated will help decrease constipation as a lack of water consumption is heavily linked as a risk factor for those who suffer from constipation at both young and older ages.

Mineral water is said to be the most beneficial type of water for this singular purpose as the sodium and magnesium it contains can help with bowel movement frequency. You can easily find and buy mineral bottled water at general stores, how many bottles you buy is up to you as there really is not a thing such as too much water.

Treats Kidney Stones

Kidney stones are a crystalized formation of minerals found in the kidney. They are incredibly painful to pass and some people are downright afraid of them, for good reason.

A higher fluid intake is linked to preventing kidney stones as it will cause more water to pass through the kidneys, hence diluting the minerals and stopping them from clumping together and crystallizing.

There is not a definitive scientific voice on this that can answer exactly how many liters or how many ounces you need before the risk is decreased, yet health experts do say there is definitely a benefit in this increased water consumption.

Prevents Hangovers

When drinking a significant amount of alcohol, it is common to wake up with a hangover and feel like you’re a loud noise away from entering the pearly gates.

The reason you get hungover is that alcohol is a diuretic. This means that when you are drinking alcohol, you are losing more water than you can consume. This leads to dehydration which is why you feel so rough in the morning.

It is not the only causing factor for hangovers. Yet it does help cause bad symptoms such as fatigue, thirst, headaches, and a dry mouth.

The best way to counter this is to have a glass of water between each alcoholic beverage. Then a larger drink right before bed. How many liters of water you drink will be determinable by how much alcohol you are drinking. So it is best to match water and alcohol consumption.

Assists Weight Loss

Drinking water and remaining thoroughly hydrated are almost essential to losing weight. While you cannot lose weight by exclusively drinking water, and you still have to put some work in, drinking water can be very helpful in the entire process.

There are two main ways that water helps you with weight loss. The first way is that water increases your metabolic rate. This is the rate at which you metabolize food and burn calories. Increased metabolism will burn more calories a day than the alternative.

The second way that water helps with weight loss is that it satiates you. This means it stops you from being so hungry.

While it depends on how much water you drink, drinking water half an hour before a meal can cause you to feel more full. This way, you do not eat excess food or binge.

So, by drinking water, you are burning more calories and consuming fewer calories.

Converting Liters

The main metrics for measuring a liquid such as water are;

  • Milliliters
  • Liters
  • Fluid Ounces
  • Cups
  • Gallons

Converting milliliters into liters is very simple as 1000 milliliters is equal to a singular liter. One Liter is equal to 33.814 U.s. customary fluid ounces.

Aside from liters and fluid ounces, another measurement is cups and gallons. Cups are usually seen in recipes that call for a gallon of milk or a cup of spinach. A cup is equivalent to 0.24 of a liter and 8.44 fluid ounces.

A gallon is roughly 4.5 liters. The number is quite long and has multiple decimal places, so rounding down to 4.5 is completely fine.
