Cups to tablespoons converter: the quick chart
For US customary measures, multiply cups by 16 for tablespoons or by 48 for teaspoons. Divide tablespoons by 16 to get cups. Use measuring spoons rather than an ordinary eating spoon.
| Cups | Tablespoons | Teaspoons |
|---|---|---|
| 1/4 | 4 | 12 |
| 1/3 | 5 1/3 | 16 |
| 1/2 | 8 | 24 |
| 3/4 | 12 | 36 |
| 1 | 16 | 48 |
Teaspoons in a tablespoon
One US tablespoon contains three US teaspoons. Half a tablespoon is 1 1/2 teaspoons. The chart and calculator use US customary spoons; a tablespoon with a different stated mL capacity needs its own measure.
Check which cup the recipe means
A US customary cup is approximately 236.588 mL. A metric cup is 250 mL. US nutrition-label measures use a 240 mL cup, as do some recipes. Those amounts are different: when a recipe gives both cups and mL, keep its stated measurement system instead of replacing it with a new conversion.
For a 240 mL cup, enter the amount in millilitres. For a 250 mL cup, choose “Metric cups.” US fluid ounces measure volume; ounces without “fluid” in this tool measure weight.
Grams to ounces converter: use weight with weight
Grams and weight ounces can be converted without knowing the ingredient. Divide grams by about 28.3495 to get ounces, or multiply ounces by that amount to get grams. For example, 100 g is approximately 3.527 oz and 8 oz is approximately 226.796 g.
A cup of flour and a cup of chocolate chips need different weights. This calculator does not convert cups to grams. Use the recipe’s own gram amount or an ingredient-specific weight from a reliable source, keeping preparation details such as chopped, sifted or packed.
Celsius to Fahrenheit oven conversion
Multiply Celsius by 9/5, then add 32 for Fahrenheit. For the reverse, subtract 32 from Fahrenheit and multiply by 5/9. An oven set to 180°C corresponds to 356°F; 350°F corresponds to approximately 176.667°C. Set the nearest suitable mark on your oven and follow the recipe’s doneness cues.
| Fahrenheit | Celsius |
|---|---|
| 300°F | 148.9°C |
| 325°F | 162.8°C |
| 350°F | 176.7°C |
| 375°F | 190.6°C |
| 400°F | 204.4°C |
| 425°F | 218.3°C |
Changing the temperature unit does not adjust a conventional oven recipe for a fan oven. Keep the recipe’s fan or conventional setting, rack position and checking instructions separate from the arithmetic.
Changing the number of servings as well?
Use the recipe serving size calculator to multiply an ingredient list for your table, then convert an individual unit here if needed. The dinner-scaling guide explains why pan space and cooking time need a separate check.

Measurement sources
Volume relationships follow NIST’s household measurement table. US customary volume and avoirdupois weight factors are based on NIST’s SI conversion factors. The temperature formulas follow NIST’s exact temperature conversions. Source review: October 22, 2026.
