Convert liquid volume measurements between US cups, fluid ounces, tablespoons, teaspoons, milliliters, and liters. Essential for cooking, baking, and beverage preparation.
Volume conversion is essential for cooking, baking, and beverage preparation. Cups, tablespoons, and teaspoons (US imperial) require conversion to or from milliliters and liters (metric) for international recipes, scientific work, and precision baking. Adding to confusion: US cup (8 fl oz, 237 ml) differs from UK cup (10 fl oz, 284 ml) and Australian cup (250 ml). For most US-context use, US measurements assumed; verify when working with international recipes.
Common conversion factors: 1 US cup = 8 fl oz = 16 tbsp = 48 tsp = 236.6 ml. 1 fl oz = 2 tbsp = 6 tsp = 29.6 ml. 1 tbsp = 3 tsp = 14.8 ml. 1 ml = 0.0042 cups = 0.034 fl oz. 1 liter = 33.8 fl oz = 4.23 cups = 1,000 ml. The US system uses 8 fl oz/cup, 16 tbsp/cup, 3 tsp/tbsp — multiples that are awkward but consistent. Metric uses powers of 10 — much simpler for calculation.
This calculator converts between cups, fluid ounces, tablespoons, teaspoons, milliliters, and liters. Use it for: international recipe adaptation, cooking precision, beverage preparation, mixology, or any liquid volume conversion. Important context: cup measurements vary by country (US 237 ml vs. UK 284 ml vs. Australian 250 ml). US recipes assume US measurements; international recipes specify. For precise baking, weight (grams) often more accurate than volume; convert if recipe provides both. Avoid mixing units within a single recipe — convert everything to consistent system before measuring. Standard kitchen measuring cups available in both US (8 oz) and metric (250 ml) sizes; verify which yours is for accuracy.
Recipe calls for 250 ml milk, 200 ml cream, 50 ml vanilla extract. Conversion: 250 ml milk = 1 cup + 1 tbsp (or 1 cup for simplicity) 200 ml cream = 3/4 cup + 1 tbsp (or 7/8 cup) 50 ml vanilla = 3 tbsp + 1 tsp (about 1/4 cup) For practical use in US measuring cups: - 250 ml milk → use 1 cup measure - 200 ml cream → use 7/8 cup measure (mark below 1 cup) - 50 ml vanilla → use 1/4 cup measure (close enough) For precision (especially in baking): use kitchen scale measuring in grams. Many European recipes give g and ml. Modern American recipes increasingly provide both cup and gram/ml measurements.
Standard cocktail recipe: 1.5 oz vodka, 0.5 oz lime juice, 2 oz cranberry juice. Conversion to ml: 1.5 fl oz × 29.6 = 44.4 ml vodka 0.5 fl oz × 29.6 = 14.8 ml lime 2 fl oz × 29.6 = 59.2 ml cranberry Total: 118.4 ml drink Standard jigger 1.5 oz = 44 ml (one jigger of vodka). Or use 2-oz jigger and pour to 3/4 mark. For consistency: use measured jiggers; don't free-pour for precise cocktails. Many home bars stocked with 0.5, 0.75, 1, 1.5, and 2 oz jiggers. Tip: most "shot" containers in bars 1-1.5 oz (varies by region/establishment). Always verify pour size.
Child medication dose: 7.5 ml liquid antibiotic, 2x daily. Convert to cooking measures? Approximately 1.5 teaspoons. But DON'T use kitchen teaspoons: - Kitchen tsp = 4.93 ml (varies by manufacturer 4.5-5.5 ml) - Medical tsp = 5.0 ml exact - Dosing variation could be 10%+ over time For medication: use marked dosing syringe or cup from pharmacy. Most pediatric medication includes appropriate measuring tool. 7.5 ml is unusual amount; usually requires precise measurement. Pharmacy can advise. Adult medication often in pill form with specific mg; liquid more common for children. NEVER use kitchen measuring spoons for medication doses. Tablespoons especially vary (US 14.8 ml; UK 17.7 ml; Australian 20 ml).

Important volume conversion considerations:
1. **Cup sizes vary by country.** US 237 ml; UK 284 ml; Australian 250 ml. Verify recipe origin.
2. **1 cup ≈ 240 ml common rounding.** Sufficient for most recipes; precise is 236.6 ml.
3. **Weight more precise than volume for baking.** Especially flour (varies 15%+ by packing).
4. **Don't use kitchen spoons for medication.** Use marked dosing syringes/cups instead.
5. **US pint = 16 oz; UK pint = 20 oz.** Notably different for beer/beverages.
6. **Tablespoon varies by country.** US 14.8 ml; UK 17.7 ml; Australian 20 ml.
7. **Liquid vs. dry measure technique.** Liquid: at eye level; dry: spoon and level.
8. **Modern recipes increasingly metric.** International accessibility; precision.
9. **Bartender measures standardized.** Jigger 1.5 oz; shot varies but commonly 1.5 oz.
10. **Standard sticks of butter.** 1/2 cup = 1 stick = 4 oz = 113 g.
11. **Specialty measures.** Pinch, dash, glug not precise — convert to standard for accuracy.
12. **Conversion direction matters.** Cups × 240 = ml; ml ÷ 240 = cups.
