Liters to Fluid Ounces (L to fl oz) Converter
Use this liters to fluid ounces converter to instantly convert L to fl oz with accurate results. Enter a volume in liters, adjust decimal precision, and get the equivalent fluid ounces value immediately.
This converter uses the formula fl oz = L × 33.814 for US fluid ounces. One liter is approximately 33.8 fluid ounces — the conversion you need when reading metric bottle sizes and translating them into the fluid ounce measurements used in US recipes, nutrition labels, and retail packaging.
Formula used: fl oz = L × 33.814

Liters to Fluid Ounces Formula
To convert liters to fluid ounces, multiply by 33.814.
Formula: fl oz = L × 33.814
For example, 0.75 L × 33.814 = 25.36 fl oz.
One US fluid ounce = 29.5735295625 mL exactly, so 1000 ÷ 29.5735295625 = 33.8140226... fl oz per liter. The commonly used factor of 33.814 is accurate to within 0.001% for any practical measurement. For reference: 1 liter is 33 fl oz plus about 0.8 of a fl oz, meaning it's slightly more than 4 cups (32 fl oz) but less than 4.25 cups.
Standard Bottle Sizes in Fluid Ounces
The liters-to-fluid-ounces conversion is especially useful for understanding bottle sizes, which are often labeled in liters but sold and consumed in fluid-ounce quantities. The 750 mL wine bottle contains 25.36 fl oz — roughly 5 standard 5-oz pours. The 1-liter spirits bottle holds 33.81 fl oz — about 22 standard 1.5-oz shots. The 1.75-liter handle holds 59.17 fl oz — approximately 39 shots. These relationships matter for bar inventory management, party planning, and per-serving cost calculations.
- 0.375 L (split/half bottle) = 12.68 fl oz
- 0.75 L (standard bottle) = 25.36 fl oz
- 1 L = 33.81 fl oz
- 1.5 L (magnum) = 50.72 fl oz
- 1.75 L (handle/half-gallon) = 59.17 fl oz

When to Convert Liters to Fluid Ounces
Beverages and spirits bottle sizing: Liquor and wine are sold globally in metric bottles (0.375 L, 0.75 L, 1 L, 1.75 L) but measured and served in fluid ounces in the US. A bar manager ordering 1.75 L handles needs to know that each bottle provides 59.17 fl oz — about 39 standard 1.5-oz shots — for inventory calculations and cost-per-drink analysis. Converting accurately prevents ordering errors and ensures cocktail pricing reflects actual pour costs.
Cooking with metric liquid ingredients: European and Asian recipes specify liquid quantities in liters and milliliters. A recipe calling for 1.5 liters of broth needs 50.72 fl oz — just over 6 US cups (48 fl oz) with a couple of extra tablespoons. US measuring tools calibrated in cups and fluid ounces can be used accurately once the liter volume is converted, preventing the common mistake of rounding 1.5 L down to 6 cups and under-measuring by nearly 3 tablespoons.
Nutrition and health tracking: Daily fluid intake recommendations are often expressed in liters or milliliters globally (e.g., "drink 2 liters of water per day") but health apps and US-centric wellness advice uses fluid ounces (e.g., "drink 64 oz per day"). The two recommendations are close but not identical: 2 liters = 67.63 fl oz, while 64 fl oz = 1.893 liters. Understanding this conversion helps people set accurate hydration targets regardless of which unit system their tracking app uses.
Cosmetics and personal care products: Imported skincare, hair care, and beauty products are sized in liters and milliliters. US consumers comparing a 250 mL (0.25 L) bottle — 8.45 fl oz — to a domestic 8 fl oz bottle (236.6 mL) will see that the imported bottle is slightly larger. For products sold by the ounce, this comparison requires converting the liter size to fluid ounces to determine the true price per fluid ounce.
FAQ
How many fl oz is 1 liter?
1 liter ≈ 33.814 US fluid ounces. This is slightly more than 4 cups (32 fl oz) — a 1-liter bottle is essentially 4 cups plus about 1.8 tablespoons extra.
How many fl oz is 2 liters?
2 liters ≈ 67.63 US fluid ounces. A standard 2-liter soda bottle contains about 67.6 fl oz — commonly approximated as "just over 67 ounces" or a little under half a gallon (64 fl oz = 0.5 gallon).
How many fl oz is a 1.75L bottle?
1.75 L ≈ 59.17 fl oz. The 1.75-liter "handle" of spirits has traditionally been marketed as "a half-gallon" in US terms, but a true half-gallon is 64 fl oz — so the 1.75 L handle is actually about 7.5% less than a true half-gallon.
How many fl oz is 0.5 liters?
0.5 liters (500 mL) ≈ 16.91 fl oz. This is just under 1 US pint (16 fl oz = 473 mL) by about 27 mL — roughly 1.8 tablespoons more than a pint.
US vs UK fluid ounces in liter conversions?
A US fluid ounce = 29.5735 mL, so 1 liter = 33.814 US fl oz. A UK fluid ounce = 28.4131 mL, so 1 liter = 35.195 UK fl oz. When reading British labels or recipes, be aware the fluid ounce is slightly smaller, meaning the same liter quantity converts to a higher number of UK fl oz than US fl oz. This converter uses US fluid ounces.
