If you have ever followed a baking recipe and wondered exactly how many grams are in a tablespoon or a cup, you are not alone. The tbsp to grams and cups to grams conversions are among the most searched cooking questions on the internet — and for good reason. Baking is precise chemistry, and even small volume variations can cause cookies to spread too thin, cakes to collapse in the center, or artisan bread to turn into a dense brick. This comprehensive guide covers everything you need to know about converting tablespoons to grams, grams to tablespoons, cups to grams, and why ingredient density is the secret to bakery-quality results.
The short answer: it depends entirely on the ingredient's physical density. 1 tbsp to grams varies widely because a tablespoon is a unit of volume (14.8 ml in the US, 15.0 ml in the metric system), not weight. A tablespoon of water weighs about 14.8 grams, while 1 tablespoon of all-purpose flour is only 7.8 grams, 1 tablespoon of granulated sugar is 12.5 grams, and 1 tablespoon of honey is a dense 21.3 grams. The formula is simple: Grams = Tablespoons × Density (grams per tablespoon).
Here are the most frequently searched tablespoon-to-gram conversions for everyday kitchen recipes:
- 2 tbsp to grams (⅛ cup / 1 fl oz): 15.6g flour, 25g sugar, 28.4g butter, 15g powdered sugar, 42.6g honey
- 3 tbsp to grams: 23.4g flour, 37.5g sugar, 42.6g butter, 22.5g powdered sugar, 63.9g honey
- 4 tbsp to grams (¼ cup / 2 fl oz): 31.2g flour, 50g sugar, 56.8g butter, 30g powdered sugar, 85.2g honey
- 5 tbsp to grams: 39g flour, 62.5g sugar, 71g butter, 37.5g powdered sugar
- 6 tbsp to grams (⅜ cup): 46.8g flour, 75g sugar, 85.2g butter, 45g powdered sugar
- 8 tbsp to grams (½ cup / 1 stick butter): 62.4g flour, 100g sugar, 113.6g butter, 60g powdered sugar
- 10 tbsp to grams: 78g flour, 125g sugar, 142g butter, 75g powdered sugar

- 16 tbsp to grams (1 full cup): 120g flour, 200g sugar, 227g butter, 120g powdered sugar, 340g honey
When scaling up recipes, measuring in cups is standard in North American cooking. Because 1 cup equals 16 tablespoons (236.6 ml), converting cups to grams requires multiplying the ingredient's cup density:
- 1 cup of all-purpose flour: 120 grams (spooned and leveled). ½ cup flour = 60g, ¾ cup = 90g, ¼ cup = 30g, 2 cups = 240g.
- 1 cup of granulated sugar: 200 grams. ½ cup sugar = 100g, ¾ cup = 150g, ¼ cup = 50g, 2 cups = 400g.
- 1 cup of packed brown sugar: 220 grams. ½ cup = 110g, ¾ cup = 165g, ¼ cup = 55g.
- 1 cup of powdered sugar (confectioners): 120 grams (sifted). ½ cup = 60g, ¾ cup = 90g, ¼ cup = 30g, 2 cups = 240g, 3 cups = 360g, 4 cups = 480g.
- 1 cup of unsalted butter: 227 grams (2 sticks). ½ cup (1 stick) = 113.4g, ¼ cup = 56.7g.
- 1 cup of cocoa powder: 100 grams. ½ cup = 50g, ⅓ cup = 33.3g, ¼ cup = 25g.
- 1 cup of rolled oats: 80 grams. ½ cup = 40g, 1 cup = 80g, 2 cups = 160g.
- 1 cup of honey or maple syrup: 340 grams (honey) or 320 grams (maple syrup). ½ cup = 170g / 160g.
Butter is one of the most frequently converted ingredients because packaging differs globally. In the United States, butter is sold in sticks:
- 1 Stick of Butter: 8 tablespoons = ½ cup = 4 ounces = 113.4 grams.
- 2 Sticks of Butter: 16 tablespoons = 1 cup = 8 ounces = 227 grams (half a pound).
- ½ Stick of Butter: 4 tablespoons = ¼ cup = 2 ounces = 56.7 grams.
- 1 European Butter Block (250g): Approximately 17.6 tablespoons (1.1 cups or ~2.2 sticks).
- 100 Grams of Butter: Exactly 7.04 tablespoons (just under ½ cup + 1 tbsp).
For leaveners and intense seasonings like salt, baking powder, baking soda, and vanilla extract, recipes call for teaspoons (1 tbsp = 3 tsp):
- 1 tsp Table Salt: 6.0 grams (½ tsp = 3.0g, ¼ tsp = 1.5g).
- 1 tsp Baking Powder: 4.6 grams (½ tsp = 2.3g, ¼ tsp = 1.15g).
- 1 tsp Baking Soda: 4.6 grams (½ tsp = 2.3g, ¼ tsp = 1.15g).
- 1 tsp Vanilla Extract: 4.33 grams (1 tbsp = 13.0g).
- 1 tsp Ground Cinnamon: 2.6 grams.
If your recipe is written in grams and you only have measuring spoons on hand, our grams to tablespoon converter reverses the calculation: Tablespoons = Grams ÷ Density.
- 5 grams to tbsp: ~0.64 tbsp flour, 0.4 tbsp sugar, 0.35 tbsp butter
- 10 grams to tbsp: ~1.28 tbsp flour, 0.8 tbsp sugar, 0.7 tbsp butter
- 15 grams to tbsp: ~1.92 tbsp flour, 1.2 tbsp sugar, 1.06 tbsp butter
- 20 grams to tbsp: ~2.56 tbsp flour, 1.6 tbsp sugar, 1.41 tbsp butter
- 25 grams to tbsp: ~3.2 tbsp flour, 2.0 tbsp sugar, 1.76 tbsp butter
- 30 grams to tbsp: ~3.85 tbsp flour, 2.4 tbsp sugar, 2.11 tbsp butter
- 50 grams to tbsp: ~6.41 tbsp flour, 4.0 tbsp sugar (¼ cup), 3.52 tbsp butter
- 60 grams to tbsp: ~7.69 tbsp flour, 4.8 tbsp sugar, 4.22 tbsp butter
- 100 grams to tbsp: ~12.8 tbsp flour (0.83 cup), 8.0 tbsp sugar (½ cup), 7.04 tbsp butter
- 125 grams to tbsp: ~16.0 tbsp flour, 10.0 tbsp sugar, 8.8 tbsp butter (standard stick)
A tablespoon is a measurement of space (volume), whereas a gram is a measurement of mass (weight). Two measuring spoons holding the exact same volume of different ingredients can have dramatically different weights:
1. Particle Packing & Aeration: When you scoop flour directly from a sack with a measuring cup or spoon, the flour compacts, packing up to 30% more weight (up to 150g per cup instead of the standard 120g). This makes cakes dense and dry. Sifting or spooning aerates the particles to reach true standard density.
2. Moisture Content & Viscosity: Brown sugar contains hygroscopic molasses, requiring it to be firmly packed into the spoon (13.8g/tbsp) to eliminate air pockets. Honey contains natural viscous fructose sugars, packing 21.3 grams into every tablespoon.
3. Temperature Fluctuations: Fats like butter expand when warm and contract when cold. Melted butter occupies less volume per unit of weight than chilled whipped butter.
If you are cooking from an international blog or cookbook, be aware of regional tablespoon variations:
- US Customary Tablespoon (14.79 ml): Used in standard American kitchen tools and recipe books. Equal to 3 US teaspoons (½ fluid ounce).
- Metric Tablespoon (15.0 ml): Used in the UK, Canada, New Zealand, and throughout Europe. Equal to 3 metric teaspoons.
- Australian Tablespoon (20.0 ml): Unique to Australia! An Australian tablespoon equals 4 metric teaspoons, making it 33.3% larger than standard US/UK tablespoons. (For instance, 1 Australian tbsp of flour weighs 10.4g compared to 7.8g US).
While our conversion tables and calculators provide instant mathematical precision based on standardized culinary densities, professional pastry chefs always recommend using a digital kitchen scale for dry and solid ingredients. Weighing your mixing bowl directly and hitting "Tare" (zero) between each ingredient saves dirtying measuring spoons, prevents over-measuring flour, and guarantees consistent, foolproof results every single bake.
