Tape this to your fridge: the ultimate kitchen conversion chart for 2026. Whether you're halving a recipe, converting grams to cups, or figuring out what temperature 180°C really is, this kitchen conversion chart has every measurement, temperature, and substitution a home cook needs. Bookmark it, print it, and never Google "how many tablespoons in a cup" again.
Kitchen Conversion Chart: Volume Measurements
The foundation of any measurement guide — volume equivalents every cook should know:
- 1 tablespoon = 3 teaspoons = 15 ml
- ¼ cup = 4 tablespoons = 12 teaspoons = 60 ml
- ⅓ cup = 5 tablespoons + 1 teaspoon = 80 ml
- ½ cup = 8 tablespoons = 120 ml
- 1 cup = 16 tablespoons = 8 oz = 240 ml
- 1 pint = 2 cups = 16 oz = 480 ml
- 1 quart = 4 cups = 32 oz = 950 ml
- 1 gallon = 16 cups = 128 oz = 3.8 liters
Scaling shortcut: To halve ⅓ cup, use 2 tablespoons + 2 teaspoons. To double it, use ⅔ cup. This section alone will save you mid-recipe panic.
For small precise amounts — spices, baking powder, yeast — volume spoons can be inaccurate. A Digital Measuring Spoon Scale weighs ingredients directly in the spoon, eliminating conversion guesswork for anything under a tablespoon. It pairs perfectly with this kitchen conversion chart — the scale handles precision, the chart handles speed.
Weight Conversions: Grams, Ounces & Pounds
Serious bakers weigh everything — and here's why it's worth it:
- 1 oz = 28 grams
- 4 oz (¼ lb) = 113 grams
- 8 oz (½ lb) = 227 grams
- 12 oz (¾ lb) = 340 grams
- 16 oz (1 lb) = 454 grams
Common ingredient weights (the part that actually matters in baking):
- 1 cup all-purpose flour = 120–125g (spooned, not scooped)
- 1 cup granulated sugar = 200g
- 1 cup brown sugar (packed) = 220g
- 1 cup butter = 227g (2 sticks)
- 1 cup honey = 340g
- 1 cup rolled oats = 90g
- 1 cup cocoa powder = 100g
Why weights vary between sources: a "cup of flour" can weigh anywhere from 120g to 150g depending on whether you spoon it in or scoop straight from the bag. Brand grind size matters too — one brand's cocoa powder packs denser than another's. When a recipe gives both cups and grams, always trust the grams. When it only gives cups, spoon flour into the cup and level it off; never scoop, which packs in up to 25% extra.
A Digital Stainless Steel Kitchen Scale makes every kitchen conversion chart calculation automatic — just set the unit to grams and weigh. Once you bake by weight, you'll never go back to cups for flour.
Oven Temperatures: °F to °C
No kitchen conversion chart is complete without a temperature table, since half the internet's recipes are in Celsius:
- 275°F = 140°C (slow roast)
- 300°F = 150°C (egg bites, custards)
- 325°F = 165°C (cakes, slow baking)
- 350°F = 175°C (the all-purpose baking temp)
- 375°F = 190°C (cookies, roasted veg)
- 400°F = 200°C (crispy roasting)
- 425°F = 220°C (pizza, high-heat roast)
- 450°F = 230°C (bread, searing)
Quick mental formula: (°F − 30) ÷ 2 ≈ °C. Close enough for most cooking. Convection adjustment: if your oven has a fan/convection mode, reduce the recipe temperature by 25°F (about 15°C) — the moving air browns faster, and this is the single most common reason convection bakes burn.

Emergency Ingredient Substitutions
The most-used section of any kitchen conversion chart — what to swap when you're missing an ingredient:
- 1 cup buttermilk → 1 cup milk + 1 tablespoon lemon juice or vinegar (rest 5 min)
- 1 cup self-rising flour → 1 cup all-purpose flour + 1½ tsp baking powder + ¼ tsp salt
- 1 teaspoon baking powder → ¼ tsp baking soda + ½ tsp cream of tartar
- 1 cup heavy cream → ¾ cup milk + ⅓ cup melted butter (not for whipping)
- 1 egg → ¼ cup unsweetened applesauce, or 1 tablespoon ground flax + 3 tablespoon water
- 1 cup brown sugar → 1 cup white sugar + 1 tablespoon molasses
- 1 tablespoon cornstarch → 2 tablespoons all-purpose flour
- 1 clove garlic → ⅛ teaspoon garlic powder
- 1 cup wine (cooking) → 1 cup broth + 1 tablespoon vinegar
- 1 cup breadcrumbs → 1 cup crushed crackers or rolled oats
When not to substitute: in delicate bakes like angel food cake or macarons, don't improvise leavening or egg ratios — the chemistry is too precise. Substitutions shine in forgiving dishes: pancakes, quick breads, soups, and sauces. Also, never swap baking soda for baking powder 1:1 (soda is roughly 4x stronger and needs an acid to activate).
For dough-based substitutions where thickness matters, an Adjustable Rolling Pin with Thickness Rings guarantees your swapped-ingredient dough still rolls to the exact thickness the recipe expects.
Handy Ratios to Memorize
Beyond the standard tables, these ratios let you cook without recipes:
- Vinaigrette: 3 parts oil to 1 part vinegar
- Rice: 1 part rice to 2 parts water (white); 1 to 2.5 (brown)
- Pasta: 4 quarts water + 1 tablespoon salt per pound
- Brine: 1 cup salt per gallon of water
- Simple syrup: 1 part sugar to 1 part water
- Pie dough: 3 parts flour, 2 parts fat, 1 part water (3-2-1)
- Pancakes: 2 cups flour, 2 eggs, 1.5 cups milk per batch
- Fresh pasta: 1 egg per 100g flour — scale to any batch size
These ratios turn your kitchen conversion chart from a lookup table into real cooking instinct. Cook with them a few times and you'll stop measuring entirely — which is the whole point of internalizing the numbers.
FAQ: Kitchen Conversion Chart
Q: What's the single most important measurement to memorize?
A: 1 cup = 16 tablespoons = 8 oz. From that single anchor you can derive almost every volume conversion on the fly.
Q: Should I trust a kitchen conversion chart or just buy a scale?
A: Both. A chart handles quick conversions, but a digital kitchen scale is more accurate for baking — flour volume varies wildly by how you scoop. Serious bakers use weight; casual cooks use the chart.
Q: How do I convert Celsius to Fahrenheit quickly?
A: Use the table above, or the quick formula: (°C × 2) + 30 ≈ °F. It's approximate but fine for everyday cooking — your oven's thermostat isn't more precise than that anyway.
Q: Can I use these tables for halving baking recipes?
A: Yes for most recipes — halve every ingredient using the volume table. The exception: leavening. Don't always halve baking powder/soda exactly; reduce by slightly less than half to keep the rise. Eggs: beat and measure half by volume (3 tablespoons = 1 large egg).
Q: What's the substitution for buttermilk?
A: 1 cup milk + 1 tablespoon lemon juice or white vinegar, rested 5 minutes until slightly curdled. It mimics buttermilk's acidity, which is what matters for tender baked goods.
Q: Is there a printable version I can keep?
A: This page is designed for it — bookmark it on your phone for cooking, or print it for the fridge. Pair it with a magnetic air fryer cheat sheet and a digital scale, and you'll rarely need to search conversions again.
