Example: One cup of water and one cup of flour occupy approximately the same volume, but they don't weigh the same. That's why “1 cup = a fixed number of grams” is not a universal cooking conversion.

For flour, sugar and similar ingredients, use dry measuring cups designed to be filled to the top and leveled. A recipe may specify a special method—follow it when it does.

1. Fluff: Stir flour gently in its container to loosen it before measuring.
2. Spoon: Spoon flour into a dry measuring cup without pressing it down.
3. Level: Sweep a straight edge across the cup to remove the excess.
4. Don't pack unless instructed: Brown sugar is frequently measured packed, but flour usually isn't.

Why it matters: Scooping flour straight from a bag can compact it, so two people measuring “one cup” may end up with different amounts. A scale avoids much of that variation.

Small amounts: For a teaspoon of vanilla or a tablespoon of oil, use a measuring spoon instead of trying to estimate the amount inside a large jug.

These familiar U.S. kitchen relationships are useful when you need to substitute one measuring tool for another.

Recipe reminder: Cup and spoon conventions differ internationally. A metric cup is often 250 mL, while the U.S. customary cup is about 237 mL. Australian tablespoons are commonly 20 mL, rather than roughly 15 mL. Check the recipe's country of origin when precision matters.

Scales are particularly helpful in baking and for sticky or awkward ingredients. They let you measure directly in grams without relying on an ingredient-specific cups-to-grams estimate.

1. Place an empty bowl or container on the scale.
2. Press Tare or Zero to remove the container's weight.
3. Add the ingredient until the display reaches the recipe's required weight.
4. Tare again before the next ingredient, if your recipe and mixing method allow it.

Example: If a recipe says “120 g flour,” weigh 120 g. Don't assume every cup of flour is exactly 120 g; that conversion depends on the flour and measuring method.
