Baking measurement is CookingCalcs' biggest content area — 9 calculators and 16 articles covering everything from cups-to-grams to egg sizing. This guide is the map: which converter to reach for, the core numbers worth memorizing, and the measuring habits that cause more baking failures than any conversion chart ever will.
Which Converter Do You Need?

| Any liquid measurement (ml, fl oz, cups, tbsp, tsp) | Liquid Converter |
| General weight (g, oz, lb, kg) | Weight Converter |
| Butter — sticks, cups, tablespoons, grams | Butter Converter |
| Egg sizes (small ↔ medium ↔ large ↔ jumbo) | Egg Size Converter |

| An ingredient you're out of (butter, eggs, buttermilk, baking powder...) | Baking Substitutions Calculator |
The Numbers Worth Memorizing
Most baking conversions you'll never need to remember — that's what the calculators are for. But a handful come up often enough to be worth knowing by heart:
- 3 teaspoons = 1 tablespoon. Full detail and a printable chart in the Tablespoons to Teaspoons guide.
- 16 tablespoons = 1 cup. See Cups to Tablespoons for the full ladder up through quarts and gallons, or How Many Cups in a Quart, Pint, and Gallon for the liquid measurement chain.
- 1 cup all-purpose flour ≈ 120g. Varies by flour type — see the full breakdown in How Many Cups in a Pound of Flour.
- 1 cup granulated sugar ≈ 200g. Brown, powdered, and coconut sugar all weigh differently per cup — see How Many Grams in a Cup of Sugar and How Many Cups in a Pound of Sugar.
- 1 stick of butter = 8 tablespoons = 113g = ½ cup. Full chart in How to Measure Butter.
- 4 large eggs ≈ 1 cup. Sizes and volume vary — see How Many Eggs in a Cup and How to Substitute Egg Sizes for converting between small, medium, large, extra-large, and jumbo.
- 350°F = 175°C = Gas Mark 4. The most common baking temperature — full conversion chart in Oven Temperature Conversion Guide.
Why Weight Beats Volume — and When It Actually Matters
A cup of flour can weigh anywhere from 115g to 150g depending on how it's scooped, while a kitchen scale gives the same 120g every time. See Why You Should Weigh Ingredients When Baking for the full case. In practice, weight matters most for structure-critical bakes — bread, macarons, laminated dough — and matters least for forgiving recipes like drop cookies or a rustic crumble, where a 10% flour variance barely changes the result.
The Measuring Mistakes That Actually Ruin Baked Goods
Between Common Baking Measurement Mistakes and Complete Cooking Measurement Guide, a few mistakes account for most baking failures:
Scooping instead of spooning. Dipping the measuring cup directly into the flour bag compacts it and can add 20-25% extra flour — enough to make a cake dense or dry. Spoon flour into the cup, then level with a straight edge.
Treating "1 cup" as identical across ingredients. A cup of flour, a cup of sugar, and a cup of butter are three different weights — see the numbers above, or convert exactly with the Cups to Grams Calculator.
Getting leavening conversions wrong. Baking powder and baking soda aren't interchangeable 1:1 — baking soda needs an acid to activate and is roughly 3-4x stronger by volume. See the Baking Substitutions Calculator for the exact ratio before swapping one for the other.
Not accounting for oven inaccuracy. Most home ovens run 25-50°F off their set point. Converting temperature correctly (°F/°C/Gas Mark) doesn't help if the oven itself is miscalibrated — an oven thermometer is the only way to know for sure.

Frequently Asked Questions
Why does 1 cup of flour not weigh the same as 1 cup of sugar?
Cups measure volume, grams measure weight, and different ingredients pack differently. A cup of flour is about 120g, a cup of sugar is about 200g, and a cup of butter is about 227g — the gap comes from particle size and density.
What's the single biggest source of measuring error in home baking?
Scooping flour or sugar directly from the container instead of spooning it in and leveling off. This can add 20-25% extra ingredient, enough to noticeably change texture — more error than any conversion chart typically introduces.
Which conversions actually need to be exact, and which can be approximate?
Leavening agents and salt need to be close to exact. Flour, sugar, and liquid tolerate more variance, usually within 5-10%. Oven temperature should be treated as exact where possible, since a small error compounds over an entire bake time.
