Tablespoons to ml — Cooking Measurement Conversion Guide
If you have a recipe using tablespoons and a measuring jug marked in milliliters, or a recipe calling for milliliters and only spoons to hand, this conversion is something you will hit often in the kitchen. It is a small conversion with a few complications — mainly because a "tablespoon" is not exactly the same size everywhere in the world.
The Volume Converter handles tablespoons, milliliters, fluid ounces, cups, and more in one place. This article explains the exact numbers, the regional variations, and gives you a practical reference table.
The US Tablespoon
1 US tablespoon = 14.787 ml
This is the standard used in American recipes, and it is the tablespoon most people mean when cooking from English-language recipes published in the US.
ml = tablespoons × 14.787
tablespoons = ml ÷ 14.787
The US tablespoon is defined as exactly 1/2 US fluid ounce, which equals 1/16 of a US cup (236.588 ml ÷ 16 = 14.787 ml). So there are exactly 16 tablespoons in a US cup.
The Metric Tablespoon (UK, Australia, New Zealand)
1 metric tablespoon = 15 ml
Australia, New Zealand, and most countries that have metricated their cooking measurements use a 15 ml tablespoon. UK recipes have largely moved to metric tablespoons at 15 ml as well, though older UK cookbooks sometimes referenced an imperial tablespoon of about 17.76 ml.
ml = tablespoons × 15
tablespoons = ml ÷ 15
The difference between 14.787 ml and 15 ml is small — about 1.4%. For most recipes, this does not matter. But if you are scaling a large recipe or doing chemistry, it is worth knowing.

| ¼ tbsp | 3.70 ml | 3.75 ml |
| ½ tbsp | 7.39 ml | 7.5 ml |
| 1 tbsp | 14.79 ml | 15 ml |
| 1½ tbsp | 22.18 ml | 22.5 ml |
| 2 tbsp | 29.57 ml | 30 ml |
| 3 tbsp | 44.36 ml | 45 ml |
| 4 tbsp | 59.15 ml | 60 ml |
| 5 tbsp | 73.93 ml | 75 ml |
| 6 tbsp | 88.72 ml | 90 ml |
| 8 tbsp | 118.29 ml | 120 ml |

| 12 tbsp | 177.44 ml | 180 ml |
| 16 tbsp | 236.59 ml | 240 ml |
Note: 16 US tablespoons = 1 US cup (236.59 ml). 16 metric tablespoons = 240 ml.

How the Tablespoon Relates to Other Measurements
In US cooking:
- 3 teaspoons = 1 tablespoon (a teaspoon is 4.929 ml; metric: 5 ml)
- 2 tablespoons = 1 fluid ounce (29.574 ml)
- 4 tablespoons = ¼ cup (59.147 ml)
- 16 tablespoons = 1 cup (236.588 ml)
- 48 teaspoons = 1 cup
In metric cooking:
- 3 teaspoons = 1 tablespoon (5 ml teaspoon; 15 ml tablespoon)
- 1 tablespoon = 15 ml exactly
- 16.67 tablespoons ≈ 1 cup (250 ml metric cup)
The metric system is more consistent because the numbers are round. 15 ml per tablespoon, 5 ml per teaspoon, 250 ml per cup — all clean multiples. The US system has slightly awkward numbers (14.787, 4.929) because it was inherited from pre-metric English measures rather than designed from scratch.
Measuring Without a Measuring Spoon
If you need to approximate a tablespoon with household items:
- A standard soup spoon holds about 10–15 ml — close to one tablespoon but varies by spoon
- A shot glass is typically 44 ml (US) or 25–35 ml (UK/EU) — 3 US tablespoons is 44.4 ml, so one shot ≈ 3 tablespoons
- A standard yogurt pot lid is often designed to hold 15 ml — check if there is a measurement stamped on it
These are rough guides. For anything where precision matters — baking leaveners, medicine, cocktails — use an actual measuring spoon or syringe.
When the Difference Between US and Metric Tablespoons Actually Matters
For most everyday cooking, the 1.5% gap between 14.787 ml and 15 ml is meaningless. A tablespoon of olive oil in a salad dressing, a tablespoon of soy sauce in a stir-fry — the small difference has no noticeable effect.
Where it can matter:
Baking: Baking is sensitive to ratios, particularly for leaveners. A recipe calling for 3 tablespoons of baking powder — already a lot — would be 44.36 ml (US) vs 45 ml (metric). That is not a meaningful difference.
Scaling up significantly: If a recipe is multiplied by 20, a 1.5% error per tablespoon accumulates. 20 × 1 tablespoon of vanilla extract = 20 tablespoons. In US measure that is 295.7 ml; in metric, 300 ml. Still only a 4.3 ml difference on a large batch — not likely to affect flavour.
Chemistry and pharmacy: Here you need to know exactly which tablespoon definition is being used. Medication instructions written in tablespoons should always specify the volume in ml as well, because kitchen measuring spoons are imprecise and the US/metric difference compounds with measuring error.
Tablespoons vs Fluid Ounces
For US recipes, tablespoons and fluid ounces are closely related:
- 1 US fluid ounce = 2 US tablespoons = 29.574 ml
- ½ fluid ounce = 1 tablespoon = 14.787 ml
This conversion is exact. So if you have a measuring jug marked in fluid ounces and need to measure tablespoons, every 2 tablespoons = 1 fluid ounce. Most liquid measuring cups show both fl oz and ml scales, which is the easiest way to bridge US recipes and metric measuring equipment.
For volume conversions beyond tablespoons — cups, liters, pints, gallons — the Volume Converter covers the full range.
