Essential Baking Measurement Conversions
A comprehensive reference for converting baking measurements between cups, grams, ounces, and tablespoons for all common ingredients.

Introduction: Why Baking Demands Precision
Baking is chemistry. Unlike cooking, where you can adjust seasoning to taste, baking requires precise ratios of flour, sugar, fat, liquid, and leavening agents. Too much flour makes bread dense; too little sugar and cookies will not brown. The challenge is that American recipes use volume measurements (cups, tablespoons) while professional bakers and international recipes use weight (grams, ounces). This guide provides the essential conversions you need to follow any recipe accurately, regardless of which measurement system it uses.
Why Weighing Beats Measuring by Volume
A “cup of flour” can weigh anywhere from 120 grams (spooned and leveled) to 150 grams (scooped and packed). That 25% variation can make or break a recipe. Professional bakers always weigh ingredients because it eliminates technique-dependent variability. If you are serious about baking, invest in a kitchen scale that reads in grams. In the meantime, use the conversions below as your reference.
Common Dry Ingredient Conversions
| Ingredient | 1 US Cup | 1 Tablespoon |
|---|---|---|
| All-purpose flour | 125 g (4.4 oz) | 8 g |
| Bread flour | 130 g (4.6 oz) | 8 g |
| Cake flour | 115 g (4.1 oz) | 7 g |
| Granulated sugar | 200 g (7.1 oz) | 12.5 g |
| Brown sugar (packed) | 220 g (7.8 oz) | 14 g |
| Powdered sugar | 120 g (4.2 oz) | 7.5 g |
| Cocoa powder | 85 g (3.0 oz) | 5 g |
| Rolled oats | 90 g (3.2 oz) | 6 g |
| Salt (table) | 288 g (10.2 oz) | 18 g |
Butter and Fat Conversions
- 1 US stick of butter = 113 g = 4 oz = 1/2 cup = 8 tablespoons
- 1 cup of butter = 227 g = 8 oz = 2 sticks
- 1 tablespoon of butter = 14 g = 0.5 oz
- 1 cup of vegetable oil = 218 g = 7.7 oz
- 1 cup of coconut oil = 218 g = 7.7 oz
Liquid Conversions
- 1 US cup = 236.59 mL = 8 fl oz
- 1 tablespoon = 14.79 mL = 0.5 fl oz
- 1 teaspoon = 4.93 mL
- 1 cup of water = 236 g (water weighs approximately 1 g per mL)
- 1 cup of milk = 245 g
- 1 cup of honey = 340 g (12 oz) — significantly heavier than water
Worked Examples
Example 1: A recipe calls for 2 cups of flour. How many grams?
2 × 125 g = 250 grams of all-purpose flour. This is the foundation of many cookie and cake recipes.
Example 2: A British recipe calls for 250 g of sugar. How many cups?
250 ÷ 200 = 1.25 cups (1 and 1/4 cups) of granulated sugar.
Example 3: Converting 3/4 cup of butter to grams
3/4 × 227 = 170 grams, or 1 and 1/2 sticks of butter.
Oven Temperature Conversions
| Description | Fahrenheit | Celsius | Gas Mark |
|---|---|---|---|
| Very low | 250°F | 120°C | 1/2 |
| Low | 300°F | 150°C | 2 |
| Moderate | 350°F | 175°C | 4 |
| Moderately hot | 375°F | 190°C | 5 |
| Hot | 400°F | 200°C | 6 |
| Very hot | 450°F | 230°C | 8 |
Real-World Applications
- Following international recipes: British, French, and Australian recipes use grams and milliliters. This chart lets you convert to cups or vice versa.
- Scaling recipes: Doubling or halving recipes is far easier with weight measurements than volumes.
- Professional baking: Bakeries use “baker's percentages” based on weight, where all ingredients are expressed as a percentage of the flour weight.

Frequently Asked Questions
How many grams are in a cup of flour?
One US cup of all-purpose flour weighs approximately 125 grams when measured with the spoon-and-level method. Scooping directly from the bag can yield 140-150 grams, which is why weighing is more accurate.
Why is weighing ingredients better than using cups?
Cup measurements vary depending on how you scoop, pack, or level the ingredient. A cup of flour can weigh anywhere from 120 to 150 grams depending on technique. A kitchen scale eliminates this variability entirely.
How many grams are in a stick of butter?
One US stick of butter equals 113 grams (4 ounces or 1/2 cup). A full standard US butter package contains 4 sticks totaling 454 grams (1 pound).
