Quick Answer
2 liters is equal to 67.628 ounces. To convert liters to ounces, multiply the liters value by 33.814.
Detailed Answer
When converting between liquid measurements, it’s important to understand the definitions of each unit. A liter is a unit of volume in the metric system. One liter is defined as the volume occupied by a cube with edges of exactly one decimeter or 10 centimeters. This comes out to exactly 1,000 cubic centimeters.
An ounce is a unit of volume in the US customary system. One fluid ounce is defined as exactly 1/128 of a US gallon.
To convert between these units, we need to know the conversion factor relating them. According to the NIST Reference on Constants, Units, and Uncertainty, one liter is equivalent to 33.814 fluid ounces.
Using this conversion factor, we can calculate how many ounces are in 2 liters:
2 liters x 33.814 ounces/liter = 67.628 ounces
So 2 liters is equal to 67.628 fluid ounces. Let’s go through the step-by-step calculation:
Step-by-Step Calculation
1. Start with the amount we want to convert: 2 liters
2. Multiply by the conversion factor:
2 liters x 33.814 ounces/liter
3. The liters unit cancels out, leaving just ounces
4. The result is: 67.628 ounces
To summarize:
- 2 liters
- x 33.814 ounces/liter
- = 67.628 ounces
So 2 liters is equivalent to 67.628 fluid ounces.
Converting Other Volumes
Using the liter to fluid ounce conversion factor, we can easily convert any volume between liters and fluid ounces. For example:
- 5 liters x 33.814 oz/liter = 168.07 oz
- 0.5 liters x 33.814 oz/liter = 16.907 oz
- 10 liters x 33.814 oz/liter = 338.14 oz
This conversion factor works both ways too. To convert fluid ounces to liters, simply divide by 33.814 instead of multiplying. For example:
- 168 oz / 33.814 oz/liter = 4.972 liters
- 84.5 oz / 33.814 oz/liter = 2.5 liters
- 507 oz / 33.814 oz/liter = 15 liters
Converting Smaller Volumes
When converting very small volumes, it can be helpful to use milliliters and fluid ounces. One milliliter is equal to 0.033814 fluid ounces.
Here are some examples of converting small volumes:
- 250 mL x 0.033814 oz/mL = 8.4535 oz
- 5 mL x 0.033814 oz/mL = 0.16907 oz
- 100 mL x 0.033814 oz/mL = 3.3814 oz
Again, we can go the other way too:
- 1 oz / 0.033814 oz/mL = 29.5735 mL
- 12 oz / 0.033814 oz/mL = 354.868 mL
- 0.5 oz / 0.033814 oz/mL = 14.7868 mL
Using milliliters and fluid ounces allows us to easily convert and work with small liquid volumes.
Converting Between Quarts, Pints, Cups, and Ounces
When cooking, we often need to convert between cups, fluid ounces, pints, and quarts. Here are some common liquid conversion factors:
- 1 cup = 8 fluid ounces
- 1 pint = 2 cups = 16 ounces
- 1 quart = 2 pints = 4 cups = 32 ounces
Using these conversion factors, we can convert measurements in recipes as needed. For example:
- If a recipe calls for 2 cups of milk, that’s equivalent to 16 fluid ounces
- If you only have a pint of cream, that’s the same as 2 cups or 16 ounces
- A quart of stock converts to 4 cups or 32 fluid ounces
Being able to easily convert between cups, fluid ounces, pints and quarts allows flexibility when cooking or following recipes.
Converting Liters to Gallons
When dealing with larger volumes of liquid, it can be useful to convert between liters and gallons. Here is the conversion factor:
- 1 liter = 0.26417 gallons
Using this, here are some example conversions:
- 5 liters x 0.26417 gallons/liter = 1.32085 gallons
- 15 liters x 0.26417 gallons/liter = 3.96255 gallons
- 0.5 liters x 0.26417 gallons/liter = 0.132085 gallons
And going from gallons to liters:
- 5 gallons x 3.78541 liters/gallon = 18.92705 liters
- 1 gallon x 3.78541 liters/gallon = 3.78541 liters
- 2.5 gallons x 3.78541 liters/gallon = 9.463525 liters
Being able to convert between liters and gallons allows us to work with volumes for tasks like filling up containers, determining capacity, mixing solutions, and more.
Converting Liquid Weight and Volume
In some situations, we need to be able to interconvert between the weight and volume of a liquid. This requires knowing the liquid’s density. Density is defined as mass per unit volume, and is commonly expressed in units of g/mL or g/cm^3.
For water at room temperature, the density is approximately 1 g/mL or 1 g/cm^3. This makes converting easy because 1 mL of water weighs 1 gram.
Here are some example water conversions:
- 250 mL of water weighs 250 grams
- 1 liter of water (1000 mL) weighs 1000 grams = 1 kilogram
- 5 grams of water is equivalent to 5 mL volume
For other liquids like oil, honey, or milk, we would need to know their density values to interconvert weight and volume. Being able to move between liquid weight and volume measurements allows us to adapt recipes, calculate shipping costs, and more. The density provides the crucial link between mass and volume.
Converting Between Metric and Imperial Units
In some applications like global trade, science, or engineering, we need to convert between metric units (liters, mL, grams) and imperial or US customary units (gallons, quarts, ounces).
Here are some key conversion factors between metric and imperial liquid units:
- 1 liter = 1.0567 quarts
- 1 milliliter = 0.033814 fluid ounces
- 1 gallon = 3.785 liters
- 1 fluid ounce = 29.57 milliliters
Using these conversion factors, we can convert measurements like:
- A 500 mL bottle holds 16.9 fluid ounces
- A 4 liter jug is equivalent to 1.057 gallons
- A 50 gallon drum holds approximately 189 liters
- 16 fluid ounces converts to 473 milliliters
Having the ability to move between metric and imperial units allows scientists, engineers, and international traders to communicate and work with measurements from different conventions.
Approximate Conversions
For quick day-to-day conversions, you don’t always need an exact value. Having some rounded equivalents memorized can help convert volumes fast for cooking, cleaning, DIY projects, and more.
Here are some handy rounded liquid conversion estimates:
- 1 liter is slightly more than 1 quart
- 1 gallon is roughly 4 liters
- 1 fluid ounce is approximately 30 milliliters
- 1 cup is nearly 250 milliliters
- 1 pint equals half a liter
So for example, if a furniture stain calls for 2 cups of water, you can estimate that’s around 500 mL. Or if you’re mixing up a batch of homemade cleaner, 1 gallon converts to approximately 4 liters.
Having a sense for these rounded conversions allows faster liquid measurement translation for common household scenarios. Always go with exact conversions when precision is needed, such as baking or chemistry.
Conversion Tables
For easy reference, conversion tables can help provide many liquid measurement equivalents in one place. Here are some common conversion values for liquid volumes:
| US Customary | Metric |
|---|---|
| 1 teaspoon | 5 mL |
| 1 tablespoon | 15 mL |
| 1 fluid ounce | 30 mL |
| 1 cup | 240 mL |
| 1 pint | 470 mL |
| 1 quart | 950 mL |
| 1 gallon | 3.8 L |
Having a printed or digital conversion table allows you to easily lookup whichever liquid conversion you need for the task at hand. No more guessing or complex math required.
Online Conversion Calculators
One final option for effortless liquid conversions is using free online conversion calculators. Sites like Convert-Me.com allow you to quickly enter the liquid volume amount and units you have, select the units you want, and it calculates the converted amount.
Online calculators are convenient for one-off conversions and eliminate the need to memorize conversion factors. They can handle exact conversions between any liquid units including cups, fluid ounces, pints, quarts, gallons, liters, milliliters, etc.
