Cooking Measurement Converter

One tablespoon is approximately 14.79 milliliters, though most recipes round this to 15 ml for simplicity. In cooking, this rounding is perfectly fine — the small difference won't affect your dish. However, for baking where precision matters more, you might want to use the exact conversion. Three teaspoons make one tablespoon, and 16 tablespoons make one cup. These relationships are consistent across both US customary and metric systems.

Converting cups to grams depends on the ingredient because different ingredients have different densities. One cup of all-purpose flour weighs about 120-125 grams, while one cup of granulated sugar weighs about 200 grams, and one cup of butter weighs about 227 grams. A cup is a volume measurement while a gram is a weight measurement, so the conversion factor changes based on what you're measuring. For the most accurate results, look up a conversion chart specific to the ingredient you're using, or use a kitchen scale to weigh ingredients directly.

A US customary cup is 236.59 milliliters, while a metric cup (commonly used in Australia, New Zealand, and some other countries) is 250 milliliters. This difference of about 13.5 ml per cup can add up in recipes that use multiple cups of liquid. For most everyday cooking, the difference is negligible, but in baking where ratios matter more, it can affect the texture and consistency of your results. When following a recipe, try to identify which cup measurement the author is using based on their location or the other units in the recipe.

To convert Fahrenheit to Celsius, subtract 32 then multiply by 5/9. For Celsius to Fahrenheit, multiply by 9/5 then add 32. Common baking temperatures: 350°F equals 177°C, 375°F equals 190°C, and 400°F equals 204°C. Many ovens have both scales marked, but if yours doesn't, this converter handles it instantly. Keep in mind that oven temperatures are approximations — most home ovens vary by 10-25 degrees from the set temperature, so an oven thermometer is a worthwhile investment for serious bakers.

Weight measurements (grams, ounces) are more accurate than volume measurements (cups, tablespoons) because they aren't affected by how tightly you pack an ingredient, humidity, or how you scoop. A cup of flour can vary by 30% or more depending on whether you scoop directly from the bag or spoon it into the measuring cup. Professional bakers and many European recipes use weight for this reason. If you're serious about consistent results, especially in baking, investing in a digital kitchen scale (they cost around $10-15) and using weight-based recipes will dramatically improve your cooking.
