About this tool
Convert US cups to tablespoons instantly. Free, bidirectional, and fully in-browser.
1 us cup equals 16 tablespoons — enter any us cup value to convert it to tablespoons instantly. This US cup to Tablespoon converter is a client-side tool: it applies a single multiplication (tbsp = cup × 16) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert tablespoons back to US cups. A reference table lists common us cup values already converted, and nothing you enter is sent to a server.
Open US cup to Tablespoon Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the US cup field.
Read the equivalent in tablespoons in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert tablespoons to US cups.
The result updates as you type, and the swap button flips the conversion to tablespoon → us cup without reloading.
The conversion uses the precise factor (tbsp = cup × 16), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.

Yes. Press the swap button, or type into the tablespoon field, and the tool converts tablespoons to US cups using the inverse of the same relationship.
It uses the standard volume and capacity definition (tbsp = cup × 16), not a rounded approximation, so results are exact to the number of decimal places you select.
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
