Tablespoon to Grams: Every Ingredient Converted
Quick answer: 1 tablespoon is NOT always 15 grams — that's only true for water. A tablespoon of flour weighs about 8g, butter is 14g, honey is 21g, and salt is 18g. The ingredient matters more than the spoon.
I used to think a tablespoon was a tablespoon. Then I tried baking French macarons using a recipe that called for "3 tablespoons almond flour" — I scooped loosely and got about 18g. The recipe actually needed 30g. Those macarons came out flat, cracked, and sad. That's when I finally bought a $12 kitchen scale, and my baking improved overnight.
But not everything needs a scale. For most cooking — sauces, marinades, seasonings — tablespoon measurements are fine. You just need to know the actual weight when precision matters.

Why Tablespoon Weights Vary So Much
A tablespoon is a volume measurement — exactly 15 milliliters. But grams measure weight. A tablespoon of feathers and a tablespoon of lead take up the same space but weigh completely different amounts.
The same is true in the kitchen:
- Flour is light and fluffy: 8g per tablespoon
- Honey is dense and heavy: 21g per tablespoon
- Water is exactly 15g per tablespoon (because 1ml of water = 1 gram, by definition)
The Salt Problem
Notice the salt section in the chart? Kosher salt brands weigh dramatically different for the same tablespoon. Morton kosher salt is 15g per tablespoon. Diamond Crystal is 9g — almost half.
This is the #1 reason recipes taste too salty or too bland when you follow them exactly. If a recipe says "1 tablespoon kosher salt" and doesn't specify the brand, they almost always mean Diamond Crystal (it's the restaurant industry standard). If you're using Morton, use about 60% of the amount called for.
Or just use a scale. Problem solved forever.
When Tablespoons Are Fine vs. When to Use a Scale
Tablespoons are perfectly fine for:
- Cooking (sauces, soups, stir-fries, marinades)
- Adding oil or butter to a pan
- Measuring spices for a recipe that serves 4+
- Any recipe where you'll adjust to taste anyway
- Baking (especially pastries, bread, macarons, anything finicky)
- Recipes from European or professional sources that give weights
- Small-batch baking where a few grams matters
- Coffee (if you're into that)
- Any recipe you've tried twice and it keeps coming out wrong
How to Measure a Tablespoon Correctly
If you're using tablespoons, at least do it right:
For dry ingredients: Spoon the ingredient into the tablespoon, then level it off with the back of a knife or a straight edge. Don't scoop directly from the container — that packs the ingredient and gives you 20-30% more than intended.
For sticky ingredients: Spray the tablespoon with cooking spray before measuring honey, maple syrup, or peanut butter. Everything slides right out instead of leaving half the measurement stuck to the spoon.
For liquids: Fill until the liquid just barely domes over the edge. Don't hold it over the bowl — fill it over the counter, then move it.
FAQ
How many tablespoons in a cup?
16 tablespoons = 1 cup. So 8 tablespoons = 1/2 cup, 4 tablespoons = 1/4 cup, and 2 tablespoons = 1/8 cup. Check our cups to grams guide for full cup conversions.
Is a tablespoon the same worldwide?
Almost. The US, UK, and most countries define 1 tablespoon as 15ml. Australia uses 20ml tablespoons. If you're following an Australian recipe, their tablespoon is 33% larger — adjust accordingly.
How many teaspoons in a tablespoon?
3 teaspoons = 1 tablespoon. This is useful when a recipe calls for 1/2 tablespoon — that's 1.5 teaspoons.
Can I convert tablespoons to ounces?
1 tablespoon = 0.5 fluid ounces (for liquids). For dry ingredients, the weight in ounces varies — use the chart above and divide grams by 28.35 to get ounces.
