Convert between tablespoons, teaspoons, and milliliters. 1 tbsp = 3 tsp = 14.787 mL. Free kitchen measurement conversion calculator.
Quickly convert between tablespoons (tbsp), teaspoons (tsp), and milliliters (mL). The key relationships are simple: 1 tablespoon = 3 teaspoons = 14.787 mL. This tool does the math for any quantity.
Spoon measurements are the most common volume units in cooking and baking recipes. Whether you are halving a recipe, scaling up for a crowd, or converting an international recipe to US measurements, this converter makes it easy.
The converter also shows cup equivalents and fluid ounce values, so you can work easily between all small-volume cooking units.
Integrating this calculation into regular planning habits ensures that work priorities reflect actual data about where time and energy produce the greatest results each week. Precise measurement of this value supports better personal and professional planning, helping you make informed decisions about how to prioritize tasks and manage competing demands.

When scaling recipes or converting between US and metric cooking measurements, spoon conversions come up constantly. This tool prevents common mistakes like confusing tablespoons and teaspoons, which can ruin seasoning or leavening in a recipe. Data-driven tracking enables proactive schedule management, helping professionals protect focused work time and reduce the cognitive overhead of constant task-switching throughout the day.
1 tablespoon (US) = 3 teaspoons = 14.787 mL = 0.5 fl oz 1 teaspoon (US) = 4.929 mL 1 cup = 16 tablespoons = 48 teaspoons = 236.588 mL
Result: 12 tsp / 59.15 mL
4 tablespoons × 3 tsp/tbsp = 12 teaspoons. 4 tablespoons × 14.787 mL/tbsp = 59.148 mL. This also equals 1/4 cup or 2 fluid ounces.
The teaspoon originated as the amount held by a small tea-stirring spoon in 18th century England. The tablespoon was the larger serving spoon. These were standardized in the US to exactly 1/6 and 1/2 fluid ounce respectively, creating the clean 1:3 ratio we use today.
For salt, spices, and leavening agents (baking powder, baking soda), the difference between a teaspoon and a tablespoon is enormous — three times the amount. Accidentally using a tablespoon of salt instead of a teaspoon will make food inedible. Always double-check your spoon size.
The US tablespoon (14.787 mL) and the UK/metric tablespoon (15 mL) are nearly identical. The Australian tablespoon (20 mL = 4 tsp) is notably larger. When following Australian recipes (common for pavlova, lamingtons, etc.), be aware of this difference.
There are exactly 3 US teaspoons in 1 US tablespoon. This is a defined relationship in the US customary system. So if a recipe calls for 1 tablespoon and you only have teaspoons, use 3 teaspoons.
One US tablespoon equals 14.787 mL. This is often rounded to 15 mL for convenience. One US teaspoon equals 4.929 mL, often rounded to 5 mL.
There are 16 US tablespoons in 1 US cup. This means 1 tablespoon = 1/16 cup. Common fractions: 4 tbsp = 1/4 cup, 8 tbsp = 1/2 cup, 12 tbsp = 3/4 cup.
No. A US tablespoon is 14.787 mL (~15 mL). An Australian tablespoon is 20 mL. A UK tablespoon is 15 mL (same as rounded US). Always check which standard your recipe uses, especially for Australian recipes.
Both are used. "tbsp" or "Tbsp" means tablespoon, while "tsp" or "t" means teaspoon. Capital "T" for tablespoon and lowercase "t" for teaspoon is a common convention, but always verify. Mixing these up is a frequent cooking mistake.
Not reliably. Eating spoons vary widely in size. A proper measuring tablespoon holds exactly 14.787 mL. An eating tablespoon might hold anywhere from 10 to 20 mL. For accuracy, always use calibrated measuring spoons.
