Measurement & Unit Conversion
Convert tablespoons to US cups, teaspoons, fluid ounces and millilitres for recipes, batching, meal prep and classroom worksheets, with scaling, rounding and a printable kitchen measurement record.
Measurement & Unit Conversion
Base tablespoons = tablespoons + extra teaspoons ÷ 3. Scaled tablespoons = base tablespoons × recipe scale multiplier. US cups = scaled tablespoons ÷ 16. US fluid ounces = scaled tablespoons ÷ 2. Millilitres ≈ scaled tablespoons × 14.78676478125.
This is the method behind the answer, so the result can be checked rather than simply trusted.Visual grid
Length, area, volume and material estimates are grid problems too: measure the space, account for edges and allowances, then turn the pattern into a number you can use.
Space calculations turn a real surface, room, run or volume into cells, edges and allowances that can be quoted, ordered or checked.

For 24 tablespoons and no extra teaspoons, cups = 24 ÷ 16 = 1.5 US cups. If the recipe is doubled, scaled tablespoons = 24 × 2 = 48 tablespoons, so cups = 48 ÷ 16 = 3 cups, or about 709.76 mL.
Master’s Tip: when converting a recipe, print the original spoon amount and the scaled cup result together. That makes it easier to reverse the change if the recipe texture needs adjusting later.
Standard or basis: US customary kitchen volume conversion. This page is for cooking, batching and classroom records, not laboratory calibration, medicine dosing, nutrition-label compliance or trade-for-legal-measurement use.
Methodology & Accuracy
CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.

Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.Master’s Tip: when converting a recipe, print the original spoon amount and the scaled cup result together.

There are 16 US tablespoons in 1 US customary cup.
Divide tablespoons by 16. For example, 24 tablespoons ÷ 16 = 1.5 cups.
There are 3 teaspoons in 1 US tablespoon, so extra teaspoons are divided by 3 before being added to the tablespoon total.
No. This calculator uses US customary cups and tablespoons. Metric cups and some regional tablespoons use different volumes.
Print the tablespoons, extra teaspoons, scale multiplier, exact cups, rounded cups, metric cross-check, formula, assumptions, page URL, date and notes about the recipe or worksheet.
Kitchen spoon-to-cup conversion is practical arithmetic, but the record matters because regional cup and tablespoon conventions are not identical. Naming the US customary basis keeps the conversion honest.
Sauces, spices, oils and baking ingredients may be written in tablespoons, while larger batch notes are easier to manage in cups. Dividing by 16 makes that scale change clear.
The same words can point to different volumes in different recipe traditions. A visible source basis prevents a US tablespoon conversion from being mistaken for every tablespoon system.
A filed conversion note with tablespoons, cups, scale multiplier and assumptions helps a cook, student or prep team repeat the same batch instead of rebuilding the conversion from memory.
