Convert grams to tablespoons and back for butter, oil, honey, peanut butter, flour, sugar and more than 30 other ingredients, in US, metric or Australian tablespoons, or use the grams-per-tablespoon figure from a nutrition label.
tablespoons = grams ÷ grams per tablespoon
A tablespoon is a volume, about 15 mL, and grams are weight. A level US tablespoon holds about 14.2 g of butter, 7.8 g of flour and 21 g of honey, so there is no single grams-to-tablespoons number. Pick the ingredient and the converter divides by its weight per tablespoon.
Only water comes close to the "1 mL = 1 g" shortcut, at 14.8 g per US tablespoon. Oils are lighter than water, and syrups and nut butters heavier.
Level US tablespoons. The last column answers the common metric-recipe question "how much is 30 g?". Flour and sugar weights match this site's cup converters (1 cup = 16 tbsp). Spices and leaveners are on the grams to teaspoons page.
| Ingredient | g per tbsp | 30 g in tbsp |
|---|---|---|
| Butter | 14.2 | 2.1 |
| Vegetable or olive oil | 13.6 | 2.2 |

| Cornstarch | 8 | 3.8 |
| Rolled oats | 5.1 | 5.9 |
A US stick of butter is ½ cup, 8 tablespoons or 113 g (4 oz), and the wrapper is marked in tablespoons, so cutting along the lines is the easiest way to measure grams without a scale. In the UK, Europe and Australia butter comes in 250 g blocks with no markings, so you'll more often need the reverse.
| Butter | Tablespoons | Measure out | US sticks |
|---|---|---|---|
| 10 g | 0.7 | 2 tsp + ⅛ tsp | 0.09 |
| 15 g | 1.1 | 1 tbsp + ⅛ tsp | 0.13 |
| 20 g | 1.4 | 1 tbsp + 1 tsp + ¼ tsp | 0.18 |
| 25 g | 1.8 | 1 tbsp + 2 tsp + ¼ tsp | 0.22 |
| 30 g | 2.1 | 2 tbsp + ¼ tsp + ⅛ tsp | 0.26 |
| 50 g | 3.5 | 3 tbsp + 1 tsp + ½ tsp + ⅛ tsp | 0.44 |
| 75 g | 5.3 | 5 tbsp + ½ tsp + ¼ tsp + ⅛ tsp | 0.66 |
| 100 g | 7 | 7 tbsp + ⅛ tsp | 0.88 |
| 113 g | 8 | 7 tbsp + 2 tsp + ½ tsp + ¼ tsp + ⅛ tsp | 1 |
| 125 g | 8.8 | 8 tbsp + 2 tsp + ¼ tsp + ⅛ tsp | 1.1 |
| 250 g | 17.6 | 17 tbsp + 1 tsp + ½ tsp + ¼ tsp + ⅛ tsp | 2.2 |
A jar says "Serving size 2 tbsp (32 g), 190 calories". You spread some on toast and the scale reads 45 g. How many tablespoons is that, and how many calories?
Step 1: Grams per tablespoon from the label
Step 2: Convert what you weighed
Step 3: Scale the calories by weight, not spoons
A generous "tablespoon" of peanut butter is often closer to two. Using the label's grams, as in step 3, is more reliable than counting spoons, because a heaped spoon of a thick spread can hold far more than a level one. Choose Custom in the converter to use any label's figure.
US Nutrition Facts labels must give the serving in a household measure and in grams. For labeling, the FDA defines a tablespoon as exactly 15 mL and a teaspoon as 5 mL, slightly larger than the 14.8 mL cooking tablespoon. The grams figure comes from the manufacturer weighing its own product, so it's the best grams-per-tablespoon number for that exact product.
Serving sizes follow FDA reference amounts: oils, butter and mayonnaise are labelled per 1 tbsp, while peanut butter and other nut butters are labelled per 2 tbsp. That's why one jar may say 2 tbsp (32 g) and the butter next to it 1 tbsp (14 g).
Most countries use a 15 mL tablespoon and the US one is within 2% of it, so they can be swapped in any recipe. Australia is the exception: its tablespoon is 20 mL, or four teaspoons, so an Australian recipe's tablespoon holds a third more.
| Tablespoon | mL | Teaspoons | Butter (g) | Flour (g) |
|---|---|---|---|---|
| US tablespoon | 14.8 | 3 | 14.2 | 7.8 |
| Metric tablespoon | 15 | 3 | 14.4 | 7.9 |
| Australian tablespoon | 20 | 4 | 19.2 | 10.6 |
Every figure on this page is for a level tablespoon. How you fill the spoon changes the weight more than the spoon size does:
About 7 US tablespoons (7.05). That is just under one US stick, which is 113 g.
About 13.6 g. Oil is lighter than water, so a tablespoon weighs less than its 14.8 mL volume suggests.
About 4 level tablespoons of granulated sugar (12.5 g each). For powdered sugar, 50 g is closer to 6⅔ tablespoons.
Only for ingredients about as dense as water. It is 15 mL, but the weight runs from about 5 g for cocoa to 21 g for honey.
