How to Measure Ingredients Accurately Without a Scale

Start with the conversion, not the guesswork

Every gram amount has a cup equivalent, as long as you know what you are measuring. That is what the tables on this site are for.

Ingredient — 100 g — 200 g — 250 g

All-purpose flour — ¾ cup — 1⅔ cups — 2 cups

Bread flour — ¾ cup — 1½ cups — 2 cups

Cake flour — 1 cup — 2 cups — 2½ cups

Granulated sugar — ½ cup — 1 cup — 1¼ cups

Brown sugar (packed) — ½ cup — 1 cup — 1⅛ cups

Butter — ½ cup — ⅞ cup — 1⅛ cups

Water or milk — ⅖ cup — ⅘ cup — 1 cup

Look the amount up rather than estimating it. Estimation is where the error comes from, not the cups themselves.

The spoon-and-level method

This is the whole technique for dry ingredients, and it is worth doing properly because it is the difference between 125 g and 150 g in the same cup.

Stir the flour in its container to loosen it.

Spoon it into the measuring cup — never drag the cup through the bag.

Let it heap above the rim.

Sweep it level with the back of a knife in one pass.

Done this way, a cup of all-purpose flour is 125 g, which is what every conversion on this site assumes. Scooped from the bag, the same cup holds 140–150 g, and a recipe using three cups ends up nearly 75 g of flour over.

Use tablespoons for small amounts

A tablespoon is too small to pack badly, which makes it more reliable than a cup for anything under about a quarter cup. Sixteen tablespoons make a cup, so the arithmetic is easy.

Ingredient — Grams per level tablespoon

All-purpose flour — 7.8 g

Granulated sugar — 12.5 g

Brown sugar (packed) — 13.8 g

Butter — 14.2 g

Cocoa powder — 5.3 g

Honey — 21.3 g

Water — 14.8 g

So 40 g of cocoa powder is about 7½ tablespoons — awkward to say, easy to count out.

Packaging is a measuring device

Manufacturers print the net weight on the pack, which turns the pack itself into a scale.

Butter. A US stick is 113 g and the wrapper is marked in tablespoons. European blocks are usually 250 g and can be cut into quarters of 62.5 g by eye with reasonable accuracy.

Yeast. A standard packet is 7 g, about 2¼ teaspoons.

Cream cheese. US blocks are 8 oz, which is 227 g.

Chocolate. Bars are commonly 100 g with scored squares — count the squares.

Tinned goods. The drained weight is printed on the label.

Bags of flour or sugar. A 1 kg bag halved gives 500 g more accurately than you can measure 500 g in cups.

Water is your calibration tool

Water weighs almost exactly 1 gram per millilitre. That single fact solves every liquid measurement without a scale: 250 ml of water is 250 g, 100 ml is 100 g.

It works closely enough for milk (a little heavier, about 1.03 g/ml), stock, wine, juice and coffee. It does not work for oil (about 0.92 g/ml), honey (about 1.44) or syrup. Those need the grams to millilitres converter, which knows each ingredient's density.

The awkward cases, solved

Half an egg. Crack it, beat it until uniform, then take half by volume. A large egg is about 50 g shelled, or roughly 3 tablespoons beaten, so half is 1½ tablespoons.

Sticky things. Oil or spray the cup before you measure honey, syrup, molasses or nut butter, and it slides out cleanly instead of leaving a tenth of itself behind. For butter, the wrapper markings are more accurate than a cup.

Brown sugar. Press it firmly into the cup with the back of a spoon until it holds the shape of the cup when tipped out. That is "packed", and it is what recipes mean.

Powdered sugar. If the recipe says sifted, sift first and then measure. Sifting after you measure gives you a different amount.

Grated cheese. How coarsely you grate changes the volume by a lot. Finely grated parmesan is about 100 g per cup; coarsely shredded cheddar is about 113 g.

What you genuinely cannot do without a scale

Be honest about the limits.

Bread hydration. Baker's percentages are ratios of weights. There is no volume equivalent, and a 5% error in water changes the dough noticeably.

Laminated pastry. Croissants and puff pastry depend on precise butter-to-dough ratios.

Tempering chocolate. The seed ratio matters and chocolate does not measure sensibly by volume.

Anything scaled to a large batch. A 5% error on one cake is invisible; on ten it is not.

For everything else — cakes, cookies, brownies, muffins, quick breads, pancakes, most cooking — careful volume measuring works fine. Millions of excellent bakes happened before domestic scales were common.

When you are ready, the cup fractions to grams page gives you the weight of every fraction, and the recipe scaler will convert a whole ingredient list at once.

Frequently asked questions

How accurate can I get without a scale?

Within about 5% for most ingredients if you spoon and level carefully. That is fine for cakes, cookies and almost all everyday cooking. Bread and laminated pastry are where the gap starts to show.

How do I measure 100 g of flour without a scale?

100 g of all-purpose flour is about ¾ cup, or 12 tablespoons plus a touch. Spoon it in and level it off rather than scooping.

Can I use a tablespoon to measure everything?

For small amounts, yes, and it is often more accurate than a cup because a tablespoon is too small to pack badly. It becomes tedious above about a quarter of a cup.

How do I measure half an egg?

Beat the egg until the yolk and white are fully combined, then measure out half. A large egg is about 50 g out of the shell, or roughly 3 tablespoons beaten, so half is 25 g or 1½ tablespoons.

Is a cheap scale worth buying?

Yes. Even an inexpensive one removes every problem on this page. The main things to check are that it reads in single grams and has a tare button.
