Have you ever followed a recipe from another country only to end up with a disaster on your plate? Maybe your cookies spread too thin, your cake didn’t rise, or your soup was far too salty. Often, the culprit isn’t the ingredients or the technique—it’s the measurement system.
Cooking (especially baking!) is a science, and accurate measurement is the foundation. However, kitchen measurements vary significantly between the US, UK, and EU, and misunderstanding them can quickly throw your dish off balance. In this guide, we’ll break down everything you need to know to confidently cook from any recipe—wherever it comes from.
1. Overview of Measurement Systems
Let’s start with a broad look at how different regions measure ingredients:
| Region | System Name | Common Units Used |
|---|---|---|
| US | US Customary | Cups, tablespoons, teaspoons, ounces (oz), Fahrenheit (°F) |
| UK | UK Imperial (historical) / Metric (modern) | Pints, fluid ounces, grams, Celsius (°C), Gas Mark |
| EU | Metric | Grams, milliliters (ml), Celsius (°C) |
- US recipes rely heavily on volume (cups, tbsp), even for dry ingredients like flour.
- UK recipes now often use grams and milliliters, though older recipes use pints and ounces.
- EU recipes are firmly metric, requiring a scale and measuring jug.
2. Liquid Measurements – US vs UK vs EU
Liquid measurements are one of the most common points of confusion, especially when switching between American and British recipes.
💧 Volume Comparison Chart
| Unit | US Volume | UK Volume | Metric Equivalent |
|---|---|---|---|
| 1 teaspoon | 4.93 ml | 5 ml | 5 ml |
| 1 tablespoon | 14.79 ml | 15 ml | 15 ml |
| 1 fluid ounce | 29.57 ml | 28.41 ml | ~30 ml |
| 1 US cup | 240 ml | 284 ml (UK cup) | — |
| 1 pint | 473 ml | 568 ml | 500 ml |
| 1 quart | 946 ml | 1.13 liters | 1 liter |
| 1 gallon | 3.78 liters | 4.54 liters | 4 liters |
📌 Important: In modern UK and EU cooking, volume is usually measured in ml or liters—so a digital measuring jug or cup with ml markers is essential.
3. Dry Measurements – Weight vs Volume
This is where it gets tricky. In the US, dry ingredients are often measured by volume (cups), while in the UK and EU, they’re measured by weight (grams). This can lead to big differences—especially in baking.
🥄 Why It Matters:
- 1 US cup of flour weighs ~120 g
- 1 US cup of sugar weighs ~200 g
- 1 cup of butter = 227 g (½ lb)
Since ingredient density varies (think packed brown sugar vs sifted flour), volume-based measurement can lead to inconsistencies. This is why digital scales are essential in UK and EU kitchens.
4. Oven Temperature Conversions – °F, °C & Gas Mark
Oven temperatures can be confusing when a recipe lists 350°F and your oven uses Celsius—or worse, Gas Mark (used in older UK ovens).
🔥 Oven Temperature Conversion Chart
| °F | °C | Gas Mark | Description |
|---|---|---|---|
| 250°F | 120°C | ½ | Very low |
| 300°F | 150°C | 2 | Low |
| 325°F | 160°C | 3 | Moderate |
| 350°F | 180°C | 4 | Moderate |
| 375°F | 190°C | 5 | Moderately hot |
| 400°F | 200°C | 6 | Hot |
| 425°F | 220°C | 7 | Very hot |
| 450°F | 230°C | 8 | Very hot |
| 475°F | 245°C | 9 | Extremely hot |
🧠 Tip: When converting recipes, always account for oven differences—some run hotter or cooler than the dial.
5. Measuring Tools by Region
Here’s what you’ll commonly find in kitchens around the world:
🇺🇸 United States
- Measuring cups for dry and liquid (¼, ⅓, ½, 1 cup)
- Measuring spoons (tsp, tbsp)
- Less use of kitchen scales
🇬🇧 United Kingdom
- Shifted toward digital scales and ml jugs in modern cooking
- Older recipes may use ounces, pints, and “knob of butter”
🇪🇺 European Union
- 100% metric: grams, milliliters, liters
- Digital scales are standard
- Recipes often call for exact weights—even for herbs and spices
📏 Pro Tip: Always check if your measuring tools are US or metric—some cups sold globally are slightly off.
6. Ingredient Conversion Table (Cups to Grams & Milliliters)
This quick-reference chart will help you convert common ingredients between US volume and metric weight—especially useful for baking.
🧁 Common Ingredient Conversions
| Ingredient | 1 US Cup = | Grams (approx.) | Milliliters (ml) |
|---|---|---|---|
| All-purpose flour | 1 cup | 120 g | — |
| Granulated sugar | 1 cup | 200 g | — |
| Brown sugar | 1 cup (packed) | 220 g | — |
| Butter | 1 cup | 227 g (2 sticks) | — |
| Milk | 1 cup | — | 240 ml |
| Water | 1 cup | — | 240 ml |
| Olive oil | 1 cup | — | 215 ml |
| Honey | 1 cup | 340 g | — |
| Rice (uncooked) | 1 cup | 180–200 g | — |
⚠️ Exact weight can vary by brand, humidity, or how ingredients are scooped. Use a scale for best accuracy.
7. Tips for Accurate Measuring
Small habits make a big difference, especially when baking. Here’s how to avoid common mistakes:
✅ Spoon-and-Level Method (for dry ingredients)
- Spoon ingredient into the measuring cup
- Level off with a knife
→ Never scoop directly with the cup—it compacts the ingredient and skews weight.
✅ Use the Right Tool
- Dry measuring cups: Flat-topped, used for flour, sugar, etc.
- Liquid measuring cups: Transparent with spout, used for milk, oil, etc.
- Measuring spoons: Level for precision; use the appropriate size (not everyday silverware).
✅ Use a Scale
- For consistent results, especially with baking, weigh in grams using a digital kitchen scale.
8. Metric vs Imperial – Which Is Better?
Let’s compare the pros and cons of each system:
| System | Pros | Cons |
|---|---|---|
| Metric | Accurate, logical (based on 10s), preferred in professional kitchens | Requires a scale; less familiar in US kitchens |
| US Customary | Fast and convenient for quick cooking | Inconsistent with weight-based recipes |
| UK Imperial | Legacy familiarity for UK cooks | Confusing mix of imperial & metric |
🎯 Verdict: For precision, especially in baking and complex cooking, metric is best. For quick cooking or casual recipes, US volume is faster—but riskier.
9. How to Convert Recipes Like a Pro
Whether you’re translating a British baking recipe or adapting a French classic, converting measurements can feel intimidating—but it doesn’t have to be.
🛠️ Pro Conversion Tips:
- Use a digital scale: This eliminates confusion about volume vs weight.
- Check units carefully: A UK pint ≠ US pint. Double-check the recipe’s origin.
- Use reliable tools: Online converters or apps like ConvertUnits, Paprika, or KitchenPro.
- Be cautious with baking: Always convert by weight, not volume, especially for flour, sugar, and leavening agents.
- Adjust seasoning: Salt measurements may vary—start low and taste as you go.

10. Conclusion
Understanding kitchen measurements across the US, UK, and EU isn’t just for advanced cooks—it’s essential for anyone cooking internationally. From cup-to-gram conversions to oven temperature changes, mastering these differences saves you time, frustration, and failed dishes.
Whether you’re cooking from an American food blog, a British baking book, or a European gourmet site, the key is this: know your measurements, trust your tools, and taste often.
11. FAQ
1. Can I use a coffee mug instead of a measuring cup?
Not reliably. Mugs vary in size. Stick with standardized measuring cups for accurate results.
2. Why are US and UK cups different sizes?
The US uses 240 ml per cup, while the UK historically used 284 ml. However, UK recipes now more commonly use grams or milliliters.
3. Is 1 tablespoon the same everywhere?
Not exactly.
- US tablespoon = 14.79 ml
- UK/Australia = 15 ml
Always check the recipe origin.
4. How do I convert Celsius to Fahrenheit easily?
Use this formula:
°F = (°C × 9/5) + 32
Or, remember rough benchmarks:
- 180°C = 350°F
- 200°C = 400°F
5. What’s the best way to measure butter?
Use a scale (grams or oz). In the US, butter sticks are pre-measured (1 stick = ½ cup = 113g).
