Estimate a tablespoon measure from a weight, or find the weight of a spoonful for a recipe. Choosing US, metric, or Australian spoons matters, especially for small quantities and concentrated ingredients.
Choose the ingredient and tablespoon
Select the conversion direction and enter your weight or spoon count. Then choose the spoon volume and ingredient. White granulated sugar is the initial preset; change it before converting flour, oil, salt, or another food.
Use a measuring tablespoon with a marked capacity. An ordinary serving spoon, a dessert spoon, or a heaped spoon is not a substitute for the specified volume. Custom density and recipe scaling are available in the options.
Why Australian recipes need attention
A 20 mL Australian tablespoon contains one third more than a 15 mL metric tablespoon. Four Australian tablespoons total 80 mL, while four metric tablespoons total 60 mL. Select the convention explicitly rather than assuming all recipes use the same spoon.
Examples
Convert a small amount of sugar
With white granulated sugar and US tablespoons, 2 tablespoons is approximately 24.75 g. Conversely, 24.75 g is approximately 2 tablespoons using the same reference.
Compare tablespoon volumes with water
For the approximate water preset, 3 metric tablespoons is about 45 g. Three Australian tablespoons is about 60 g. The difference comes from spoon volume, not a different water density.
Formula
Grams = tablespoons × tablespoon mL × ingredient density
Tablespoons = grams ÷ (tablespoon mL × ingredient density)
For the US option, one tablespoon is exactly one sixteenth of a US customary cup in this model. Metric and Australian options use 15 mL and 20 mL respectively.
Reading fractional spoon results
An output such as 1.5 tablespoons means one and a half of the selected tablespoon. If your measuring set cannot measure the fraction accurately, weigh the amount or use the teaspoons tool with the correct convention. Do not assume a tablespoon always equals three teaspoons: a 20 mL spoon equals four 5 mL teaspoons.
References and uncertainty
Ingredient quantities are based on King Arthur Baking’s ingredient weight chart, normalized to US recipe measures before scaling by spoon size. NIST’s household measurement guidance discusses common kitchen measures, and Taste’s chart lists the Australian 20 mL tablespoon. Packing and product differences remain even when the arithmetic is precise.
