International Culinary Volumetric Standards (NIST & ISO)

Tablespoon volumes differ slightly across international borders:

• US Customary Tablespoon: 0.5 US fl oz = 3 tsp = 14.786765 mL

• Metric / UK / Canada / NZ / US FDA: 15.000 mL Exact = 3 Metric tsp

• Australian Tablespoon: 20.000 mL Exact = 4 Metric tsp = 0.676 fl oz

Primary Culinary Conversion Benchmarks Table

• 0.5 tbsp (1.5 tsp): 7.39 mL = 0.25 fl oz

• 1.0 tbsp (3.0 tsp): 14.79 mL = 0.50 fl oz

• 2.0 tbsp: 29.57 mL

• 4.0 tbsp: 59.15 mL

• 8.0 tbsp: 118.29 mL = 1 Stick Butter

• 16.0 tbsp: 236.59 mL

Equations

• Milliliters (mL) = Tablespoons (tbsp) × 14.7868

• Tablespoons (tbsp) = Milliliters (mL)14.7868

How to Use This Calculator

Enter your Volume Value to Convert (e.g. 2), Regional Tablespoon Standard — choose from US Customary (14.787 mL / 0.5 fl oz / 3 tsp), Metric, UK, Canada & NZ (15.000 mL Exact), Australian Standard (20.000 mL / 4 tsp), Culinary & Kitchen Benchmark — choose from Custom Volume Value, 0.5 tbsp (7.39 mL / 1.5 Teaspoons), 1.0 tbsp (14.79 mL / 3 Teaspoons / 0.5 fl oz), and Conversion Direction — choose from Tablespoons to Milliliters (tbsp → mL), Milliliters to Tablespoons (mL → tbsp).

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
