Practical guide
Know what a kitchen conversion does—and does not—change
Start with the kind of measurement
Kitchen conversions fall into two distinct groups. Volume units describe how much space something occupies, while weight units describe its mass. Cups can be converted to milliliters, and ounces of weight can be converted to grams. Moving from cups to grams requires the identity and density of the ingredient; this general converter does not supply a universal answer for that jump. Understanding that boundary prevents the common mistake of treating a cup of flour, a cup of oil, and a cup of chopped nuts as interchangeable weights.
Check the label before entering numbers
Read the recipe's unit carefully, including whether ounces mean fluid ounces or ounces of weight. Enter the amount, choose compatible starting and destination units, and keep the unrounded result until you decide how to measure it. US customary cups are not the same as every international cup convention. If a recipe is written around a 250-milliliter cup, preserve that convention instead of assuming its cups match the tool's US-volume setting. For ingredient-specific cup-to-gram estimates, use the baking converter or the recipe author's own weight measurements.
Use the result in a real meal
For a household of four, a sauce recipe might need 750 milliliters of stock while your jug shows US cups. Convert the volume, measure it in the jug, and reserve a little liquid if the recipe expects you to adjust consistency at the end. For six people, scale the recipe's quantities first, then convert the final amounts into convenient units. Keep tablespoons and teaspoons clearly labeled when preparing small bowls of seasonings. A written prep list is more reliable than switching repeatedly between recipe instructions, mental arithmetic, and a crowded counter.
Avoid false precision at the stove
A conversion can be mathematically precise while your measuring equipment is not. A large pitcher is a poor way to measure a teaspoon, and a scale reading in whole grams cannot reliably resolve every tiny spice quantity. Choose equipment appropriate to the amount. Converting a soup's liquid does not predict evaporation, saltiness, or the pot capacity required after vegetables are added. Check that the saucepan can comfortably hold the complete batch, and allow extra heating time for a larger quantity. Taste and texture remain cooking decisions; the converter's job is to put equivalent measurements in a usable form.

Methodology
How we calculate this
Compatible measurements are converted through a shared base unit. Weight and volume stay separate because density is ingredient-specific.
The math
- Converted amount = amount × source base factor ÷ target base factor
- US volume base = cups
- Mass base = grams
Worked example
One US cup × 1 cup ÷ 0.00422675 cup per mL equals about 236.6 mL.
Frequently asked questions
Helpful answers
How many tablespoons are in 100 mL?
One hundred milliliters is about 6.8 US tablespoons, or approximately 6 tablespoons plus 2 teaspoons.
Can I convert one cup of chopped nuts to grams exactly?
Not exactly. The variety, chop size, and packing change the weight, so use a published weight for the specific nut and cut as a starting point.
Why can't cups of flour or sugar be converted to grams with one universal formula?
A cup measures volume while grams measure weight. Different ingredients have different densities, and packing or measuring technique can change how much fits in the cup.
A practical starting point
Use the result as a planning estimate, then trust the ingredients, your thermometer, and the food in front of you. This tool is designed to make the first calculation easier—not to replace good kitchen judgment.
