When it comes to cooking, baking, nutrition, or even shipping, accurate measurements are essential. Ounces (abbreviated as oz) are one of the most commonly used units in both the U.S. customary system and the British imperial system. However, many people get confused between fluid ounces (volume) and dry ounces (weight). That’s where the Oz to Oz Calculator comes in—helping you easily and accurately convert one type of ounce measurement to another.
Oz To Oz Calculator
An ounce (oz) is a small unit of measurement, but it can mean two different things depending on the context:
- Fluid Ounce (fl oz): Used to measure volume, such as liquids like milk, water, or juice.
- Dry Ounce (oz): Used to measure weight, such as flour, sugar, nuts, or other dry ingredients.
This dual meaning often creates confusion. For example, 8 fluid ounces of water equals 1 cup, but 8 ounces of flour by weight is not the same volume as 8 fluid ounces. The Oz to Oz Calculator helps you clarify whether you are working with weight or volume, and ensures your conversions are correct.
What Is an Oz to Oz Calculator?
The Oz to Oz Calculator is an online tool designed to simplify conversions between fluid ounces and dry ounces. It is particularly useful for:

Conversion Formula
While the calculator does the math for you, here are the formulas for better understanding:
- 1 U.S. fluid ounce (fl oz) = 29.5735 milliliters (ml)
- 1 U.S. dry ounce (oz) = 28.3495 grams (g)
Because fluid ounces measure volume and dry ounces measure weight, there is no fixed “1 to 1” formula between them. The conversion depends on the density of the ingredient or liquid.
For example:
- 1 fluid ounce of water ≈ 1.04 ounces by weight.
- 1 fluid ounce of olive oil ≈ 0.91 ounces by weight.
This is why the Oz to Oz Calculator is especially useful—it takes the guesswork out of conversions.
Practical Examples
Example 1: Baking Flour
- A recipe calls for 16 ounces of flour by weight.
- The user mistakenly thinks it means 16 fluid ounces.
- Using the calculator clarifies that 16 dry ounces = 1 pound, not 2 cups of flour.
Example 2: Measuring Water
- A smoothie recipe asks for 8 fluid ounces of water.
- Using the calculator: 8 fl oz = about 236.6 ml = about 8.34 dry ounces by weight.
Example 3: Cooking Oil
- A salad recipe requires 2 fluid ounces of olive oil.
- The calculator shows that this equals about 1.82 dry ounces (by weight).
These examples highlight why having a reliable conversion tool saves time and prevents recipe errors.

Additional Tips for Ounce Conversions
- Always check whether a recipe uses weight (oz) or volume (fl oz).
- For dry ingredients, weighing on a kitchen scale is more accurate than using volume.
- For liquids, fluid ounces are better measured in cups or milliliters.
- Remember: Different liquids weigh differently. For example, honey is heavier than water.
