How to Convert Recipe Measurements for Any Kitchen
Cups to grams, ounces to milliliters, and everything in between — with the exact conversions cooks actually need.
You found the perfect recipe online. Then you read the ingredients: 250 grams of flour, 180 milliliters of milk, 4 ounces of butter. Your measuring cups are in cups and tablespoons. Now what?
Recipe conversion is one of the most common everyday uses of unit conversion — and one of the most frustrating. Here's how to handle it without ruining dinner.
The golden rule: weight beats volume
Professional bakers weigh their ingredients. There's a reason: a cup of flour can weigh anywhere from 120 to 160 grams depending on how you scoop it.
When a recipe gives you weights (grams, ounces), use a kitchen scale. When it gives you volumes (cups, tablespoons), you're at the mercy of your scooping technique.
The essential conversions every cook should know
| Ingredient | 1 cup equals | 1 tablespoon equals |
|---|---|---|
| All-purpose flour | 120 g | 8 g |
| Granulated sugar | 200 g | 12 g |
| Brown sugar (packed) | 220 g | 13 g |
| Butter | 227 g | 14 g |
| Water / milk | 240 ml | 15 ml |
| Honey / syrup | 340 g | 21 g |
Volume conversions (US standard)
- 1 cup = 16 tablespoons = 48 teaspoons
- 1 tablespoon = 3 teaspoons = 15 ml
- 1 fluid ounce = 2 tablespoons = 30 ml
- 1 cup = 8 fluid ounces = 240 ml
- 1 pint = 2 cups = 473 ml
- 1 quart = 4 cups = 946 ml
- 1 gallon = 16 cups = 3.785 liters
Weight conversions
- 1 ounce = 28.35 grams
- 1 pound = 16 ounces = 453.59 grams
- 1 kilogram = 1000 grams = 2.2 pounds
Temperature conversions for cooking
- 325°F = 165°C (slow oven)
- 350°F = 175°C (moderate — the most common)
- 375°F = 190°C (moderately hot)
- 400°F = 205°C (hot)
- 425°F = 220°C (very hot)
- 450°F = 230°C (extremely hot)

The most common recipe conversion mistakes
- Scooping flour directly from the bag. This compacts the flour and adds up to 30% extra weight. Spoon it into the cup instead.
- Converting ounces to fluid ounces. An ounce is weight; a fluid ounce is volume. Different things entirely.
- Rounding liquid measurements. 240 ml of water vs 250 ml is a 4% difference — enough to matter in baking.
- Assuming US and UK cups are the same. A US cup is 240 ml; a UK cup is 250 ml; an Australian cup is 250 ml. Small difference, occasionally significant.
- Forgetting about ingredient density. 1 cup of flour and 1 cup of honey do not weigh the same thing.
The best way to convert recipe measurements
If you cook a lot, a kitchen scale is worth its weight in gold. Set it to grams, tare it between ingredients, and you'll never have to think about conversions again.
If you don't have a scale, or you just need a fast conversion mid-recipe, our free weight converter handles grams, kilograms, ounces, and pounds. Live results, no sign-up, works on your phone while your hands are sticky.
The bottom line
- Weights beat volumes for accuracy — especially in baking
- Know your ingredient densities — 1 cup of flour ≠ 1 cup of sugar
- Don't confuse weight ounces with fluid ounces
- Use a converter when the numbers don't line up
Recipe conversion gets easier with practice, and much easier with the right tools. Between a good kitchen scale and a free weight converter, you'll never ruin a batch of cookies again.
