Kitchen Conversion Chart: Cups to Grams, Ounces, Tablespoons, and Milliliters

Overview

This guide is designed as a practical kitchen conversion chart rather than a one-off list. The goal is simple: give you a clear reference you can return to when a recipe calls for volume, your scale reads weight, or an ingredient needs a more precise measurement than “about a cup.”

The most important principle comes first: weight is usually more consistent than volume, especially in baking conversions. A cup of flour can vary depending on whether it was scooped, spooned, sifted, or compacted. A scale removes that uncertainty. Volume still has its place for liquids and quick everyday cooking, but when you want repeatable cakes, breads, cookies, or pastry, grams are often the easiest path to consistency.

Here are the base conversions worth memorizing:

• 1 tablespoon = 15 ml
• 1 teaspoon = 5 ml
• 1 cup = 240 ml in most U.S. recipe contexts
• 1 fluid ounce = about 30 ml
• 1 ounce = about 28 g
• 1 pound = 16 ounces = about 454 g

Those base figures help with liquids and general recipe reading, but ingredients such as flour, sugar, butter, cocoa powder, rice, and oats each convert differently from cups to grams. That is why a conversion chart for ingredients is more useful than a simple math table.

Use this article when you need to:

• Convert cups to grams for baking
• Convert ounces to grams for packaged ingredients
• Convert tablespoons to ml for sauces, dressings, and liquids
• Scale recipes with fewer errors
• Move between metric and U.S. measurements with more confidence

Topic map

This section collects the conversions home cooks use most often and organizes them by task. Think of it as the quick-look center of the hub.

Core liquid conversions

For water-like liquids, these volume conversions are the most dependable starting point:

• 1 teaspoon = 5 ml
• 2 teaspoons = 10 ml
• 1 tablespoon = 15 ml
• 2 tablespoons = 30 ml
• 4 tablespoons = 60 ml
• 1/3 cup = 80 ml
• 1/2 cup = 120 ml
• 2/3 cup = 160 ml
• 3/4 cup = 180 ml
• 1 cup = 240 ml
• 2 cups = 480 ml
• 4 cups = 960 ml
• 1 liter = 1000 ml

These are especially useful for stock, milk, cream, water, juice, and similar liquids. For thicker ingredients such as honey, yogurt, sour cream, or nut butter, volume conversions still work, but weight may be more accurate if texture matters.

Ounces to grams conversion

Recipes, packaging, and imported ingredients often switch between ounces and grams. This quick table covers the most common amounts:

• 1 oz = 28 g
• 2 oz = 57 g
• 3 oz = 85 g
• 4 oz = 113 g
• 5 oz = 142 g
• 6 oz = 170 g
• 8 oz = 227 g
• 10 oz = 283 g
• 12 oz = 340 g
• 16 oz = 454 g

For many home recipes, rounding to the nearest gram is more than accurate enough. If a packaged ingredient says 8 ounces, treating it as 227 grams is standard kitchen practice.

Cups to grams chart for common baking ingredients

This is where a general cooking conversion chart becomes a truly useful baking tool. Cup weights vary by ingredient, so convert based on what the ingredient actually is, not just the container size.

• All-purpose flour: 1 cup = about 120 g
• Bread flour: 1 cup = about 120 to 127 g
• Cake flour: 1 cup = about 110 to 115 g
• Granulated sugar: 1 cup = about 200 g
• Brown sugar, packed: 1 cup = about 220 g
• Powdered sugar: 1 cup = about 120 g
• Butter: 1 cup = 227 g
• Cocoa powder: 1 cup = about 85 g
• Rolled oats: 1 cup = about 90 g
• Rice, uncooked: 1 cup = about 185 to 200 g
• Honey: 1 cup = about 340 g
• Greek yogurt: 1 cup = about 240 g

These figures are practical kitchen averages, not rigid laws. Brand, grind, moisture level, and packing method can shift the result slightly. When a recipe gives both cups and grams, follow the grams first.

Butter conversions

Butter appears in many forms across recipes: sticks, tablespoons, ounces, cups, and grams. A dedicated chart removes guesswork.

• 1 tablespoon butter = about 14 g
• 2 tablespoons = about 28 g
• 4 tablespoons = 1/4 cup = about 57 g
• 8 tablespoons = 1/2 cup = about 113 g
• 1 cup = 227 g

Butter is one of the easiest ingredients to convert because it behaves predictably by weight. For pastry and cookies, weighing butter is often more reliable than working from spoon marks alone.

Dry spoon conversions

Small measurements matter, especially in baking basics and seasoning blends.

• 1 tablespoon = 3 teaspoons
• 1/2 tablespoon = 1 1/2 teaspoons
• 1/4 cup = 4 tablespoons
• 1/3 cup = 5 tablespoons + 1 teaspoon
• 1/2 cup = 8 tablespoons
• 3/4 cup = 12 tablespoons
• 1 cup = 16 tablespoons

These are the conversions many cooks use when halving or doubling recipes without a full recipe scaler. They are also useful when you need to measure from tools you already own.

Related subtopics

Measurements are only part of the story. A good conversion hub should also help you understand where kitchen math intersects with technique, ingredients, and equipment.

Why cups to grams matters more in baking than in savory cooking

In a soup, stew, pan sauce, or weeknight skillet dinner, small variation often disappears into the final dish. In a sponge cake or lean bread dough, the same variation can affect rise, tenderness, spread, or crumb. That is why baking conversions deserve more care than a casual dinner recipe.

If your muffins turn out dense or your cookies spread too much, inaccurate flour and sugar measurement may be part of the problem. Switching from cups to grams can tighten up your results without changing the recipe itself.

Ingredient density changes the answer

One cup does not mean one weight across ingredients. Flour is lighter than sugar. Brown sugar weighs more when packed. Oats are light and airy compared with honey. Cocoa powder can clump. This is the central reason “1 cup = X grams” is not a universal statement.

When in doubt, look up the exact ingredient rather than relying on a generic cup-to-gram formula.

How measuring style changes volume results

Even if two people use the same measuring cup, their results can differ. Common methods include:

• Scooping directly from the bag: often packs more into the cup
• Spoon-and-level: usually gives a lighter, more consistent flour measure
• Sifting first: changes volume significantly for some ingredients
• Packing: expected for brown sugar, not for flour

This is one reason conversion charts are best treated as guides paired with good measuring habits.

Metric vs U.S. recipes

Recipes from different regions may define a cup differently, and they may rely more heavily on weight or volume. For a home cook, the easiest way to reduce confusion is to decide early whether you are following the recipe in metric or in U.S. customary terms, then convert carefully and consistently rather than mixing systems halfway through.

Temperature and time still matter

A precise measurement helps, but it does not replace attention to oven behavior, pan material, mixing method, or ingredient temperature. If you are converting a baking recipe, try to keep everything else as stable as possible. A conversion chart works best when it supports technique instead of replacing it.

How to use this hub

The best way to use a conversion guide is not to memorize every number. It is to build a quick routine that reduces friction in the kitchen.

1. Start by identifying the ingredient type

Ask whether you are converting a liquid, a fat, a powder, a grain, or a sweetener. Water and milk follow volume rules neatly. Flour and sugar do not share the same weight. Butter has its own dependable chart. This first step prevents the most common mistake: treating all cups as equal.

2. Use grams for baking whenever possible

If your recipe includes grams, use them. If it does not, convert carefully and write the result directly on your printed recipe card or notes app. The second time you make the recipe, you will not need to repeat the work.

3. Round sensibly

Home cooking does not require laboratory precision. Rounding 113.4 grams to 113 grams is fine. Even 112 or 114 grams is unlikely to affect most recipes. The bigger risk is using the wrong ingredient conversion altogether.

4. Keep a short personal chart

Every cook returns to the same ingredients: flour, sugar, butter, oats, rice, milk, oil. Build a small personal reference from the chart above and keep it where you cook. A note inside a cabinet door, recipe binder, or phone note can save a surprising amount of time.

5. Scale recipes by weight, not volume

If you halve or double a cake, bread, or cookie recipe, scaling by grams is usually cleaner than trying to divide awkward spoon and cup measures. This is where a simple conversion table turns into a practical serving size calculator method: convert first, then scale second.

6. Mark assumptions when needed

If a recipe is vague, note your assumption. For example: “flour measured as 120 g per cup” or “brown sugar packed.” That single line can help you troubleshoot later if the texture is off.

7. Pair the chart with stronger kitchen habits

Conversions are most useful when your overall method is steady. Level dry measures, preheat fully, use the pan size specified, and avoid crowding several changes into one recipe attempt. Good conversion habits work best inside a consistent cooking routine.

When to revisit

This hub is meant to be revisited, not read once and forgotten. Return to it whenever your cooking becomes more precise, your ingredient list expands, or your recipes begin moving across regions and measurement systems.

It is worth revisiting when:

• You start baking more often and want repeatable results
• You buy a kitchen scale and want to convert favorite recipes
• You begin using imported cookbooks or international websites
• You work with ingredients not listed in your usual notes
• You scale recipes for meal prep, parties, or smaller households
• You notice recurring problems with texture, rise, or consistency

A practical next step is to create your own living chart. Start with ten ingredients you use every week. Add exact gram notes after each successful bake or recipe test. Over time, that personal list becomes faster and more trustworthy than a generic chart because it reflects your ingredients, your tools, and your cooking style.

If you want this hub to work harder for you, do three things today:

1. Save or print the core conversion list
2. Choose one recipe you make often and rewrite it in grams
3. Keep a short note of any ingredient-specific weights you confirm in your own kitchen

That small effort pays off every time you cook under time pressure, substitute measuring tools, or move between recipe formats. A good kitchen conversion chart is not just a reference page. It is a quiet piece of kitchen infrastructure that makes everyday cooking smoother and baking more dependable.
