A tablespoon of honey weighs nearly three times as much as a tablespoon of flour. That single fact explains why “just convert it” is never simple, and why so many bakers get frustrated. To convert grams to tablespoons, here is the key insight: there is no universal conversion because a tablespoon measures volume while a gram measures weight.
The fix is a simple formula that works for every ingredient. In this guide you’ll learn the exact formula, a ready-made chart for the 12 ingredients you convert most, and a one-line method that makes tablespoon math instant.

Grams to Tablespoons: The Direct Answer
Grams to tablespoons refers to converting a weight measurement (grams) into a volume measurement (US tablespoons) for a specific ingredient. One US tablespoon holds 14.79 milliliters, so the gram weight of a tablespoon depends entirely on the ingredient’s density. Water is the baseline: one tablespoon of water weighs 15 grams.
Quick Answer: To convert grams to tablespoons, divide the grams by the ingredient’s grams-per-tablespoon value. One tablespoon of water equals 15 grams, one tablespoon of all-purpose flour equals about 8 grams, and one tablespoon of granulated sugar equals about 12.5 grams. There is no single multiplier that works for everything.
Why Tablespoons and Grams Do Not Convert 1:1
A gram measures mass. A tablespoon measures volume. Converting between them requires knowing how much mass fits in that volume, which is the ingredient’s density. Dense ingredients like honey pack more grams into a tablespoon than airy ones like flour. Any chart that gives one universal number is wrong, and honestly, those charts cause more ruined recipes than any other measuring myth.
US vs Metric Tablespoons
A US tablespoon equals 14.79 milliliters. A metric tablespoon, used in the UK and Australia, equals 15 milliliters, and an Australian tablespoon is actually 20 milliliters. The differences are small but they add up across a whole recipe. This guide uses US tablespoons throughout.
Convert Grams to Tablespoons: The Formula
The 14.8 Density Method
Here is my original framework for every tablespoon conversion: the 14.8 Density Method. It has one formula:
Tablespoons = grams / (14.8 x density in g/ml)
Since one US tablespoon holds 14.8 milliliters (rounded), multiplying by the ingredient’s density gives you the grams in one tablespoon. Divide your grams by that number and you have tablespoons. Three inputs, one answer, every ingredient, every time.
Worked Example: 100 Grams of Flour
All-purpose flour has a density of about 0.53 g/ml. Plug it in: 100 / (14.8 x 0.53) = about 12.8 tablespoons. In practice, round to 13 tablespoons or just weigh the flour. The same formula turns 50 grams of honey (density 1.42) into about 2.4 tablespoons. Notice how density does all the work.
Q: Can I convert grams to tablespoons without knowing the density? A: Not accurately. You need the density or a published grams-per-tablespoon value. The chart below covers the most common ingredients, so most cooks never look one up.
The Reverse: Tablespoons to Grams
Flip the formula: grams = tablespoons x 14.8 x density. Two tablespoons of butter (density 0.95) gives about 28 grams, which matches the familiar “2 tablespoons = 1 ounce” kitchen rule.

|---|---|---|---|
| Water, milk | 15 g | 3.3 tbsp | 6.7 tbsp |
| Butter | 14 g | 3.6 tbsp | 7.1 tbsp |
| Vegetable oil | 14 g | 3.6 tbsp | 7.1 tbsp |
| Honey | 21 g | 2.4 tbsp | 4.8 tbsp |
| All-purpose flour | 8 g | 6.3 tbsp | 12.5 tbsp |
| Granulated sugar | 12.5 g | 4 tbsp | 8 tbsp |
| Powdered sugar | 7.5 g | 6.7 tbsp | 13.3 tbsp |
| Table salt | 18 g | 2.8 tbsp | 5.6 tbsp |
| Cocoa powder | 6 g | 8.3 tbsp | 16.7 tbsp |
| Peanut butter | 16 g | 3.1 tbsp | 6.3 tbsp |
| Rolled oats | 5.6 g | 8.9 tbsp | 17.9 tbsp |
| Baking powder | 12 g | 4.2 tbsp | 8.3 tbsp |
How to Use This Chart in 4 Steps
- Find your ingredient’s grams-per-tablespoon value in the chart.
- Divide your gram amount by that value.
- Round to the nearest half tablespoon for cooking, or quarter tablespoon for baking.
- For ingredients missing from the chart, use the 14.8 Density Method with a quick density lookup.

Gram to Tablespoon Conversions by Ingredient
Flour: The Tricky One
Flour is the hardest common ingredient because its density shifts with humidity, brand, and how you fill the spoon. One tablespoon of spooned-and-leveled flour weighs about 8 grams, but a scooped tablespoon can hit 10. For baking, weigh flour instead of converting.
Sugar: Granulated vs Powdered
Granulated sugar packs neatly at 12.5 grams per tablespoon. Powdered sugar is much airier at about 7.5 grams per tablespoon. Mixing these two up is a classic frosting disaster, so double check which sugar your recipe means.
Butter and Oils
Butter is the easy one: one tablespoon weighs 14 grams, and most US butter sticks are marked in tablespoon lines. Vegetable oil is nearly identical at 14 grams per tablespoon. For bigger batches, our grams to cups oil guide covers cup-scale oil conversions. These are the conversions you can safely do in your head, and a gram or two either way will not change a saute or a cake.
Liquids: Water, Milk, and Honey
Water and milk sit at 15 grams per tablespoon, the baseline everything else is measured against. Honey is the heavyweight at 21 grams per tablespoon. Tip: lightly oil the spoon before measuring honey and it slides right off.
Q: How many tablespoons is 30 grams of butter? A: About 2.1 tablespoons. Butter runs 14 grams per tablespoon, so 30 divided by 14 gives just over 2 tablespoons. Most cooks would round to 2 tablespoons.
Q: Why does my tablespoon of flour weigh 10 grams instead of 8? A: You are scooping instead of spooning. Scooping compresses flour into the spoon and adds 2 to 3 grams. Spoon flour loosely into the tablespoon and level it off for the published 8-gram value.
Pro Tips and Common Mistakes
Pro Tip: When a recipe gives grams and you only have spoons, convert the most sensitive ingredient (usually flour or leavening) and eyeball the rest. Precision matters most where chemistry matters most.
Mistake 1: Using One Conversion for Everything
The number one error is treating “1 tablespoon = 15 grams” as universal. That is only true for water-like liquids. For flour it overstates by nearly double. Always use the ingredient-specific value.
Mistake 2: Confusing Tablespoon and Teaspoon
One tablespoon equals 3 teaspoons. In a rush, cooks sometimes convert grams to teaspoons by mistake and triple the amount. Label your result clearly before measuring.
Mistake 3: Ignoring the Tablespoon Standard
UK and Australian tablespoons can be 15 or 20 milliliters instead of the US 14.79. For spice-heavy recipes the difference is negligible, but for baking it can shift results. When in doubt, check the recipe’s origin.

FAQ
How many tablespoons is 100 grams of flour?
100 grams of all-purpose flour equals about 12.5 tablespoons, since flour runs roughly 8 grams per US tablespoon. For baking, weighing beats converting, because scooping changes flour density.
How many tablespoons is 50 grams of sugar?
50 grams of granulated sugar equals exactly 4 tablespoons at 12.5 grams per tablespoon. For powdered sugar, lighter at 7.5 grams per tablespoon, 50 grams equals about 6.7 tablespoons.
What is the formula to convert grams to tablespoons?
Divide grams by 14.8 times the ingredient’s density in g/ml. In practice, use a chart value: tablespoons = grams / (grams per tablespoon for that ingredient). The chart above lists values for 12 common ingredients.
How many tablespoons is 30 grams of honey?
About 1.4 tablespoons. Honey is dense at 21 grams per tablespoon, so a little volume carries a lot of weight. Lightly oil your spoon first so the honey releases cleanly.
Is a tablespoon of salt really 18 grams?
Yes, for standard table salt. Its fine, dense crystals pack tightly at about 18 grams per US tablespoon. Coarse kosher salt is much lighter per tablespoon, around 10 to 12 grams, because of its hollow flakes.
How many grams is 2 tablespoons of butter?
Two US tablespoons of butter weigh about 28 grams, which is exactly 1 ounce. This is one of the most useful kitchen equivalents to memorize, since butter packaging is often marked in tablespoon lines.
Can I use grams to tablespoons for baking?
You can, but weighing is better for baking. Conversions introduce rounding error, and flour density varies with how you fill the spoon. For cakes, breads, and pastries, a kitchen scale beats any conversion chart.
Why do online converters give different answers for the same ingredient?
They use different density assumptions. One converter may assume sifted flour while another assumes scooped, shifting the answer by 20 percent or more. Pick one trusted source and stay consistent.
Conclusion
Three takeaways: a tablespoon measures volume (14.79 ml), so gram conversions always depend on density; the 14.8 Density Method converts any ingredient with one formula; and the chart above covers the 12 ingredients you will actually convert. Memorize the water baseline of 15 grams and butter at 14, and look up the rest.
Your next steps: memorize the per-tablespoon values for your three most-converted ingredients, bookmark this chart for the rest, and explore our kitchen weight conversions hub when recipes scale up to cup quantities.
