Understanding fluid ounces to milliliters: a helpful guide for home cooks
Learn how to convert 1 oz to ml in your kitchen for precise results
Whether you're baking cookies, mixing cocktails, or preparing salad dressings, knowing how to convert 1 oz (fluid ounce) to milliliters (ml) can help you follow recipes from around the world with ease. In this guide, we explore how many milliliters are in 1 oz and how that measurement applies to various ingredients in real cooking scenarios.
How many mls in 1 oz of water for cooking?
When converting water, 1 fluid ounce equals approximately 29.57 ml. For practical purposes in the kitchen, this is usually rounded to 30 ml. Water’s consistent density makes it one of the simplest ingredients to convert. You’ll often use this conversion when measuring liquids for boiling pasta, making rice, or steaming vegetables.
Converting 1 oz of milk to ml – what’s the right amount for baking?
Milk shares a similar density with water, so 1 oz of milk is also around 29.57 ml. This is helpful when you're trying to replicate American baking recipes that require small amounts of milk in ounces. Using the correct amount ensures your batter or dough consistency remains accurate.
How many milliliters is 1 oz of olive oil in salad dressings?
Olive oil is slightly lighter than water, but the difference is minimal. For most cooking purposes, 1 oz of olive oil equals about 29.5 ml. In salad dressings, precise measurement can impact both the flavor and texture, especially when emulsifying with vinegar or citrus juices.
What is 1 oz of melted butter in ml when baking cookies or cakes?
Melted butter converts similarly to oil, so 1 oz is approximately 28.5–30 ml depending on temperature and brand. Since butter solidifies when cooled, it’s important to measure it in its liquid form if the recipe specifies melted butter.
How many mls in 1 oz of lemon juice for marinades or drinks?
Freshly squeezed or bottled, 1 oz of lemon juice equals about 29.5 ml. This is commonly used in marinades for poultry or fish, and in lemon-based beverages. Consistency in acidity is key, so sticking to precise measures helps maintain a balanced flavor.
How to convert 1 oz of vinegar to ml for sauces and dressings?
Most culinary vinegars (like white, apple cider, or balsamic) have densities close to water. So 1 oz vinegar = ~29.5 ml. When preparing vinaigrettes or pickling solutions, using the right ratio of vinegar to other liquids is essential for preserving taste and safety.
1 oz to ml for heavy cream – ideal measurements for desserts
Heavy cream or whipping cream is slightly thicker, but still close in density to milk. For conversions, 1 oz = roughly 29.3 ml. In desserts like ganache, panna cotta, or mousse, precision in cream quantity affects texture and richness.
How many ml in 1 oz of wine for cooking sauces?
When cooking with wine, especially in sauces or reductions, 1 oz = 29.5 ml. Whether it’s white wine for chicken piccata or red wine for a stew, knowing the right amount prevents overpowering the dish or wasting wine.
How much is 1 oz of honey in ml for sweet recipes?
Honey is denser than water, so 1 oz of honey is about 21.3 ml. This is due to its thickness and sugar content. Measuring honey correctly ensures that your desserts or glazes aren’t overly sweet or sticky.
1 oz of soy sauce to ml – measuring correctly for stir fry and Asian dishes
Soy sauce is slightly lighter than water, coming in at around 29 ml per ounce. It’s widely used in Asian cuisine, where balance between sweet, salty, and umami flavors is crucial. Proper conversion helps replicate the authentic taste.
How many ml in 1 oz of tomato paste or puree for pasta sauces?
Tomato paste is thick and dense, so 1 oz equals about 28 ml. This is often important in pasta sauces, stews, and braises, where tomato paste provides concentrated flavor and color.
1 oz of coconut milk in ml – essential for curries and exotic dishes
Coconut milk’s consistency varies depending on brand and fat content, but on average 1 oz = 29.5 ml. In Thai curries, rice dishes, or smoothies, using the correct amount ensures creamy texture and flavor integrity.
How many milliliters in 1 oz of whiskey for cocktails?
In mixology, precision is everything. 1 oz of whiskey = 29.57 ml. Whether you're making an Old Fashioned, Manhattan, or Whiskey Sour, converting this correctly maintains the intended strength and balance of the drink.
Converting 1 oz of orange juice to ml – right dose for smoothies or drinks
Orange juice, like water, converts easily at 1 oz = 29.5 ml. Used in smoothies, breakfast drinks, or glazes for meats, this conversion ensures you get the right level of sweetness and acidity.
How many ml is 1 oz of broth or stock in soups and stews?
Broth and stock vary slightly in density based on fat content, but a general rule is 1 oz = 29.5 ml. Whether it’s vegetable broth in risotto or beef stock in stews, converting accurately helps maintain liquid-to-solid ratios.

With this knowledge, you can confidently cook and bake with recipes from any region, without compromising on texture, taste, or proportions.
