Teaspoons to Tablespoons Converter - Convert tsp to tbsp Instantly

About Teaspoons to Tablespoons Conversion

Teaspoons (tsp) and tablespoons (tbsp) are both volume measures used widely in recipes, nutrition guidance, beverage formulation, and small-volume lab work. In the US customary system, the relationship is exact: 1 tablespoon = 3 teaspoons. That means you can convert tsp to tbsp simply by dividing by 3, which keeps your calculations reproducible and easy to audit.

Keep in mind that not all regions use the same tablespoon size. A US tablespoon is 14.78676478125 mL, while a metric tablespoon is 15 mL, and an Australian tablespoon is 20 mL (which equals 4 metric teaspoons of 5 mL). This page targets the US relationship specifically.

Teaspoons to Tablespoons Formula

Use the direct ratio:

tbsp (US) = tsp (US) ÷ 3

Example:

7.5 tsp ÷ 3 = 2.5 tbsp (US)

To convert in the opposite direction: tsp (US) = tbsp (US) × 3.

US vs Metric vs Australian Spoons

The US teaspoon is 4.92892159375 mL and the US tablespoon is 14.78676478125 mL, preserving the 3:1 ratio. A metric teaspoon is 5 mL and a metric tablespoon is 15 mL, also 3:1. An Australian tablespoon is 20 mL, which produces a 4:1 ratio with the 5 mL metric teaspoon. Always check which standard your recipe or device uses.

What is a Teaspoon?

A teaspoon is a small kitchen measure for liquids and fine dry ingredients. In the US customary hierarchy, it equals 1/3 of a tablespoon and 1/48 of a US cup. Its exact relationship to tablespoons is why the tsp→tbsp conversion is a simple divide-by-3.

What is a Tablespoon?

A tablespoon is a larger kitchen measure used for liquids and some dry ingredients. In the US system it equals 3 teaspoons and 1/16 of a US cup. It’s a convenient unit for scaling recipes and simplifying small measurements.

Step-by-Step: Converting tsp to US tbsp

1. Write down your volume in US teaspoons (tsp).
2. Divide by 3.
3. Express the result in US tablespoons (tbsp).

Example walkthrough:

Input:  8.5 tsp (US)
Divide: 8.5 ÷ 3 = 2.83333
Output: 2.83333 tbsp (US)

Precision, Rounding & Significant Figures

For everyday cooking, 2–3 decimals are usually enough, but this tool defaults to 5 for consistency across pages. In professional contexts (R&D, QA, clinical), match significant figures to your instruments and reporting standards to avoid rounding bias in chained calculations.
