The internet's standard advice is to weigh everything. It is good advice, and it is delivered with a certainty that does not quite survive contact with a Tuesday evening. Here is the honest version.
The case for grams
- Reproducible. 250 grams is 250 grams whether you are rushing, distracted, or using someone else's measuring cups. There is no technique variable at all.
- Faster than it sounds. Bowl on the scale, press tare, pour until the number is right, press tare again for the next ingredient. No levelling, no second cup, nothing extra to wash.
- Fewer things to wash. Most of a baking recipe can go into one bowl on a scale. Cup measuring means a nested set plus spoons.
- Scales cleanly. Multiplying 250 by 1.5 is trivial. Working out what one and a half cups plus two thirds of a cup comes to, and then measuring it, is not.
- Handles sticky ingredients. Honey, syrup and peanut butter weighed straight into the bowl beats scraping them out of a measuring cup and guessing how much stayed behind.
- Travels. A gram is a gram in every country. A cup is not.
The case for cups
Cups are not indefensible, and pretending otherwise makes the advice easy to dismiss:
- No equipment barrier. Every kitchen already has them. A scale is one more thing to buy, store and keep batteries in.
- Faster for liquids in everyday cooking. Nobody needs to weigh the water for rice or the stock for a soup.
- Fine for forgiving food. Most savoury cooking does not care about a 10% variance in anything.
- Matches the recipes you already have. If your entire collection is in cups, working in grams means converting constantly, which introduces its own errors.
- Better for very small amounts. Most domestic scales resolve to 1 gram, which is useless for 2 grams of yeast. Measuring spoons win here outright.
Where the difference genuinely bites
Volume measuring fails when two things are true at once: the ingredient is compressible, and the recipe is sensitive to ratios.
| Ingredient | Volume measuring | Why |
|---|---|---|
| Flour | Poor | Compresses; 27% spread by technique |
| Brown sugar | Poor | Packing changes it by a third |
| Cocoa, powdered sugar | Poor | Fine powders that clump and compress |
| Chopped nuts, shredded cheese | Poor | Depends on the cut |
| Granulated sugar | Good | Hard crystals that do not compress |
| Butter | Good | Sold in marked sticks or blocks |
| Water, milk, stock | Good | Liquids fill the cup completely |
Bread is the clearest case for weighing. Hydration — the ratio of water to flour by weight — determines how the dough behaves, and you cannot control a ratio when one side of it varies by 27% depending on how you filled a cup.
A practical middle ground
You do not have to pick a side. What most experienced home bakers actually do:
- Weigh flour, sugar, butter, and anything you need more than about a cup of.
- Use cups for water, milk, stock and anything in a forgiving savoury dish.
- Use spoons for salt, spices, vanilla, yeast and leavening — quantities too small for a domestic scale to resolve.
That gets you nearly all the accuracy benefit without turning dinner into a laboratory exercise.
If you buy one thing
A digital scale with a tare button, ideally reading in 1 gram increments and switchable between grams and ounces. They are among the cheapest items in a kitchen shop, take up less drawer space than a set of measuring cups, and pay for themselves the first time a loaf comes out the way it was supposed to.
What to look for in a scale
Most of the features scales advertise do not matter. The ones that do:
- A tare button. Non-negotiable. It zeroes the display so you can weigh ingredients one after another into the same bowl.
- 1 gram resolution. Anything coarser is useless for baking. Finer is unnecessary unless you are weighing yeast.
- A capacity of at least 5 kg. You need headroom for the bowl before the ingredient goes in.
- A flat top. Easier to clean and takes larger bowls than a recessed platform.
Things you can ignore entirely: body-fat-style extras, app connectivity, nutritional databases. They add cost and failure points to a device that needs to do one thing.
Two common objections
"It is another thing to wash." It is the opposite. Weighing into one bowl replaces a nested set of cups and a set of spoons. Wipe the scale afterwards.
"My recipes are all in cups." True at first, and it fades. Convert each recipe once as you cook it, note the grams in the margin, and within a few months the collection has migrated itself.
Converting the recipes you already have
You do not need to convert your whole collection at once. Convert a recipe the next time you make it, write the gram figures in the margin, and keep the original alongside for the first bake. After one successful run the gram version becomes the one you use.
Our recipe converter will take a whole ingredient list at once, and the cups to grams converter handles individual lines if you would rather work through them one at a time.
