What are the core baking conversions?
One US cup is 16 tablespoons or 48 teaspoons. One tablespoon is 3 teaspoons or ½ fluid ounce. One gallon is 256 tablespoons. For weight, one ounce is 28.35 grams. Volume conversions like these never depend on the ingredient — only weight-to-volume conversions do. That distinction is the one worth committing to memory. Cups, tablespoons, teaspoons, fluid ounces, pints and gallons all measure volume, so the ratios between them are fixed by definition and hold for water, flour and honey alike. The moment grams or ounces of weight enter, density decides the answer and the ingredient has to be named: one cup is always 16 tablespoons, but one cup is 200 g of sugar and only 120 g of flour. Note too that a fluid ounce measures volume while an ounce measures weight — unrelated units that happen to share a word.
This is the reference hub for every conversion that does not involve a specific ingredient's density. Cups to teaspoons, tablespoons to fluid ounces, gallons to tablespoons, grams to ounces — all fixed ratios that hold regardless of what you are measuring.
It also covers the international differences that cause the most trouble: the US cup at 236.6 ml against the metric cup at 250 ml, and the Australian tablespoon at 20 ml against everyone else's 15 ml. Getting either of these wrong will visibly change a bake.
For conversions that do depend on the ingredient — anything turning grams into spoons or cups — use the ingredient-aware calculators linked at the bottom of this page.
The fixed ratios
US customary volume units are defined in terms of each other, so these ratios are exact rather than approximate.
Teaspoons to tablespoons
3 teaspoons in 1 tablespoon. This holds in US, metric and imperial systems alike.
Tablespoons to cups
16 tablespoons in 1 US cup, which is also 48 teaspoons.
Cups to gallons
16 cups in 1 US gallon, giving 256 tablespoons or 768 teaspoons.
Grams to ounces
1 ounce is 28.3495 grams. This is a weight conversion, so it is the same for every ingredient.
| 1 tablespoon | 3 tsp = ½ fl oz = 14.79 ml |
|---|---|
| 1 US cup | 16 tbsp = 48 tsp = 8 fl oz = 236.6 ml |
| ½ cup | 8 tbsp = 24 tsp = 4 fl oz |
| ⅔ cup | 10⅔ tbsp = 32 tsp |
| ⅓ cup | 5⅓ tbsp = 16 tsp |
| ¼ cup | 4 tbsp = 12 tsp = 2 fl oz |
| 1 pint | 2 cups = 32 tbsp = 473 ml |
| 1 quart | 4 cups = 64 tbsp = 946 ml |
| 1 US gallon | 16 cups = 256 tbsp = 768 tsp = 3.785 l |
| 1 ounce (weight) | 28.35 g |
| 1 pound | 16 oz = 453.6 g |
| 1 stick of butter | 8 tbsp = ½ cup = 113 g = 4 oz |
Worked examples
The unit questions that come up most often outside grams and cups.
Tablespoons in a gallon
= 256
16 cups × 16 tablespoons. Also 768 teaspoons, which is worth knowing when scaling a recipe to catering volume.
Teaspoons in ½ cup
= 24
8 tablespoons × 3 teaspoons. Useful when a recipe gives a large quantity in teaspoons.
⅔ cup in teaspoons
= 32
10⅔ tablespoons × 3. A rare case where the thirds cancel out to a whole number.
1 tablespoon in fluid ounces
= 0.5 fl oz
By definition. This is why 2 tablespoons is 1 fluid ounce and ¼ cup is 2.
130 g in ounces
≈ 4.59 oz
130 ÷ 28.35. A weight-to-weight conversion, so the ingredient is irrelevant.
5 g in teaspoons
≈ 1.2 tsp sugar
This one does depend on the ingredient: 5 g is 1.2 tsp of sugar but 1 tsp of water.
Accuracy and assumptions
All volume conversions use US customary units unless explicitly labelled otherwise. Within that system the ratios are exact by definition, so there is no rounding error to accumulate.
The metric cup of 250 ml is used across Europe, Australia and New Zealand and is 5.7% larger than the US cup. Measuring-cup sets rarely state which standard they follow, so if yours came from outside the US, assume metric.
The Australian tablespoon of 20 ml is the largest single trap in this chart. It holds 4 teaspoons rather than 3, so any recipe converted with the wrong spoon will be off by a third on every spoon measurement.
Weight conversions between grams and ounces are exact: 1 oz = 28.349523125 g. Only the display is rounded.
Key facts
256 tablespoons in a US gallon
16 cups × 16 tablespoons. The imperial gallon used in the UK is larger at 4.546 litres, giving 307 US tablespoons.
24 teaspoons in half a cup
Because there are 48 in a full cup. Teaspoon figures scale linearly with cups, unlike weight.
A tablespoon is half a fluid ounce
Which makes 2 tablespoons exactly 1 fl oz, and a US cup exactly 8 fl oz.
An ounce of weight is not a fluid ounce
28.35 g of weight against 29.57 ml of volume. They coincide only for water, and only by accident of definition.
A US stick of butter is 8 tablespoons
½ cup, 113 g, or 4 oz. The four figures on a US butter wrapper, all describing the same block.
Metric cups are 5.7% larger than US cups
250 ml against 236.6 ml. On a four-cup recipe that is more than half a cup of difference.
Quick answers
Direct answers to the unit questions searched for most.
How many tablespoons are in a gallon?
256 tablespoons in a US gallon. That is 16 cups, or 768 teaspoons. An imperial (UK) gallon holds about 307 US tablespoons.
How many teaspoons are in ½ cup?
24 teaspoons, since there are 48 teaspoons in a full US cup.
How many teaspoons are in ⅔ cup?
32 teaspoons — one of the few cup fractions that gives a whole number.
1 tablespoon equals how many ounces?
Half a fluid ounce by volume. By weight it depends on the ingredient: a tablespoon of sugar is 0.44 oz and a tablespoon of butter is 0.5 oz.
What is 130 g in ounces?
About 4.59 ounces. Divide grams by 28.35 to convert.
How many teaspoons is 5 grams?
About 1.2 teaspoons of granulated sugar, 1 teaspoon of water, or 1.7 teaspoons of flour. This conversion does depend on the ingredient.
How many tablespoons are in a cup?
16 in a US cup, for any ingredient, since both units measure volume.
What does tsp mean?
Teaspoon. Tbsp means tablespoon, and one tablespoon is three teaspoons. The abbreviations are easy to misread, so recipes often capitalise T for tablespoon and leave t lowercase for teaspoon.
