The Ultimate Guide: How Many Ounces (oz) Are In 375 ML? (And Why This Bottle Size Matters)

Understanding volume measurements is crucial in many aspects of modern life, from following a precise cooking recipe to correctly sizing up a beverage container. As of today, December 12, 2025, the most common conversion question involving this specific volume is: "How many ounces are in 375 ml?" The short, definitive answer for the United States standard is that 375 milliliters (mL) is precisely equal to 12.68 US fluid ounces (fl oz).

This seemingly simple conversion opens up a fascinating world of standard container sizes, especially within the global beverage industry. The 375 mL bottle is not just a random volume; it is a standardized, highly significant size known by different names—the "Half-Pint" in liquor or the "Demi" in wine—making its ounce equivalent essential knowledge for bartenders, home cooks, travelers, and connoisseurs alike.

The Definitive 375 mL to Ounce Conversion Chart (US vs. Imperial)

When converting milliliters (mL) to ounces (oz), you must first clarify which type of ounce you are using: the US Fluid Ounce or the Imperial Fluid Ounce. The US system is prevalent in the United States, while the Imperial system is used in the UK and some Commonwealth nations. The difference is small but critical for accuracy.

• The US Fluid Ounce (US fl oz): The conversion factor is 1 mL ≈ 0.033814 US fl oz.
• The Imperial Fluid Ounce (Imp fl oz): The conversion factor is 1 mL ≈ 0.035195 Imp fl oz.

Using these precise conversion factors, here is the breakdown of 375 mL in both systems:

For almost all practical purposes, especially in North America, the 12.68 US fluid ounces figure is the one you need to remember. This volume is half the size of the standard 750 mL bottle, which is approximately 25.36 US fl oz.

The Many Identities of the 375 mL Bottle: Half-Pint, Split, and Demi

The 375 mL size is one of the most common and versatile container volumes in the beverage world, far exceeding its simple mathematical conversion. Its small, convenient size has earned it several distinct and important names depending on the product it contains. Knowing these names is a key part of understanding the world of wine and spirits.

375 mL in the Liquor Industry: The Half-Pint

In the spirits and liquor industry, the 375 mL bottle is almost universally known as the Half-Pint. This name is a nod to historical measurement systems, even though an actual US liquid pint is closer to 473 mL (16 US fl oz). The 375 mL size is popular because it offers a perfect mid-range option between the smaller 200 mL (miniature) and the standard 750 mL bottle.

• Common Spirits: Whiskey, Vodka, Rum, Tequila, and specialty liqueurs are often sold in this size.
• Consumer Intention: It is ideal for sampling a new brand, moderate consumption, or for consumers who do not want to commit to the larger, more expensive 750 mL 'Fifth' bottle.

375 mL in the Wine & Champagne World: The Demi or Half-Bottle

In the world of viticulture, the 375 mL bottle has a more elegant set of names: the Demi or the Half-Bottle. It is also sometimes referred to as a "Split" when discussing Champagne or sparkling wine, though a true Split/Piccolo is often 187.5 mL.

• Perfect for Two: The 375 mL size holds approximately 2.5 standard glasses of wine, making it the perfect volume for sharing a couple of glasses over dinner without opening a full 750 mL bottle.
• Specialty Wines: This size is particularly popular for dessert wines, fortified wines like Port and Sherry, and high-end vintages, as it allows consumers to try a premium product at a lower price point.
• Hospitality Use: The Demi is a staple in the hospitality sector, frequently found in hotel minibars, on airline carts, and aboard cruise ships due to its convenient single- or double-serving size.

Practical Applications: From Bartending to Baking

Knowing the 375 mL to oz conversion is more than just academic; it has direct, real-world utility in several key areas. These practical applications highlight why this specific volume is so important in global commerce and daily life.

How Many Shots Are in a 375 mL Bottle?

For anyone stocking a home bar or planning a party, the most common practical question is "how many shots are in a Half-Pint?"

The industry standard for a single shot in the United States is 1.5 fluid ounces.

Given that 375 mL is 12.68 US fl oz, the calculation is straightforward:

12.68 US fl oz / 1.5 US fl oz per shot = 8.45 Shots

Therefore, a 375 mL bottle provides approximately 8 standard shots of liquor. This is a neat, easily remembered number that is exactly half the 16 shots found in a standard 750 mL bottle.

375 mL to Ounces for Cooking and Baking

In the kitchen, the conversion from metric (mL) to imperial (oz) is a frequent necessity, especially when dealing with international recipes. While 375 mL is 12.68 US fl oz, it is often more useful to convert it to cups for easy measurement with standard kitchen tools.

• Cups Conversion: Since 1 US cup is 8 US fl oz, 375 mL (12.68 oz) is equivalent to approximately 1.58 US cups.
• Weight vs. Volume: It’s important to remember that this is a volume conversion. If a recipe calls for "ounces by weight" (like flour or sugar), the conversion will change based on the density of the ingredient. However, for liquids like water, milk, or broth, the 12.68 fl oz conversion is highly accurate.

Step-by-Step Guide to Milliliter to Ounce Conversion

If you ever need to perform this conversion for other volumes, the process is simple. Use the conversion factor as your key:

Formula: Volume in Ounces = Volume in Milliliters × Conversion Factor

Step 1: Choose Your Ounce Type

Decide whether you need US or Imperial ounces. For most people in the US, the US Fluid Ounce factor is the correct choice.

• US Factor: 0.033814
• Imperial Factor: 0.035195

Step 2: Apply the Formula

For 375 mL to US Fluid Ounces:

375 mL × 0.033814 = 12.679875 US fl oz (Rounded to 12.68 fl oz)

Step 3: Quick Checks and Rounding

For quick mental math or estimations, you can use the approximation that 30 mL is roughly 1 US fl oz. This provides a fast, though slightly less precise, result:

375 mL / 30 mL per oz ≈ 12.5 US fl oz

This quick estimation is very close to the actual 12.68 fl oz, making it a handy trick for on-the-spot calculations when a calculator isn't available.

The Importance of Metric and Imperial Standards

The need for conversions like 375 mL to oz highlights the ongoing coexistence of the metric system and the US customary system. The metric system, based on units of ten (milliliters, liters), is used by the vast majority of the world's population, making it the global standard for scientific and international trade. The US customary system, which includes fluid ounces, pints, and quarts, remains the standard for consumer goods and personal use within the United States.

The 375 mL bottle size is a perfect example of a metric standard that has been fully integrated into the US market. By understanding its equivalent of 12.68 US fluid ounces, you bridge the gap between these two measurement worlds, making you a more informed consumer, a more accurate cook, and a more efficient bartender.
