Volume Converter
Volume conversions: 1 liter = 1000 mL = 0.264 US gallons = 33.8 fl oz. 1 US gallon = 3.785 L = 128 fl oz = 16 cups. 1 cubic meter = 1000 L. For example, 2 liters = 0.53 gallons = 67.6 fl oz. Metric: mL → L (÷1000) → m³ (÷1000). Imperial: fl oz → cups (÷8) → gallons (÷16). Common: water bottle 500 mL, milk jug 1 gallon (3.8L), gas tank 15 gallons (57L), swimming pool 20,000 gallons (76,000L).

Frequently Asked Questions
- How do I convert liters to gallons?
- To convert liters to US gallons, multiply by 0.264172. Formula: US gallons = liters × 0.264172. For example, 10 liters = 10 × 0.264172 = 2.64 gallons. To convert gallons to liters, multiply by 3.78541. For example, 5 gallons = 5 × 3.78541 = 18.93 liters. Note: UK imperial gallons differ (1 UK gallon = 4.546 liters). Always verify which gallon standard applies.
- What is the difference between US and UK gallons?
- One US gallon equals 3.785 liters, while one UK (imperial) gallon equals 4.546 liters — about 20% larger. This difference stems from historical definitions. US fluid measurements (gallons, quarts, pints) are based on the wine gallon, while UK measurements used the ale gallon. When converting, always specify US or UK gallons. Most modern recipes and fuel measurements use liters to avoid confusion.
- How many milliliters are in common volume measurements?
- Common conversions: 1 teaspoon (tsp) = 5 mL, 1 tablespoon (tbsp) = 15 mL, 1 fluid ounce (fl oz) = 29.57 mL, 1 cup = 237 mL (US) or 250 mL (metric), 1 pint = 473 mL (US) or 568 mL (UK), 1 quart = 946 mL (US), 1 liter = 1000 mL. These conversions are essential for recipe scaling, medicine dosing, and international cooking.
- How do I convert between cubic meters and liters?
- One cubic meter (m³) equals exactly 1,000 liters. Formula: liters = cubic meters × 1000. For example, 2.5 m³ = 2,500 liters. To convert liters to cubic meters, divide by 1000. For example, 5,000 liters = 5 m³. This conversion is used in engineering, construction (concrete volume), water consumption (utility billing), and shipping (cargo volume). Cubic meters measure large volumes; liters measure everyday quantities.
- What are fluid ounces and how do they convert to milliliters?
- Fluid ounces (fl oz) measure volume, not weight. One US fluid ounce equals 29.5735 milliliters (≈ 30 mL). One UK fluid ounce equals 28.4131 mL. Common conversions: 8 fl oz (1 cup) = 237 mL, 16 fl oz (1 pint) = 473 mL, 32 fl oz (1 quart) = 946 mL. Do not confuse fluid ounces (volume) with ounces (weight) — they measure different properties.
- How do I convert volume for cooking and baking?
- For liquids, use volume conversions directly: cups to mL (1 cup = 237 mL), tbsp to mL (1 tbsp = 15 mL), tsp to mL (1 tsp = 5 mL). For dry ingredients, weight is more accurate than volume (1 cup flour can vary 120-150g depending on packing). Professional recipes specify grams. When adapting recipes, convert liquid volumes but weigh dry ingredients. Use a kitchen scale for best results.
- What is the difference between volume and capacity?
- Volume and capacity are often used interchangeably but have subtle differences. Volume measures the space an object occupies (any substance), while capacity measures how much a container can hold (liquids or substances). Example: a bottle has a capacity of 500 mL (how much liquid it holds) and a volume of 600 cm³ (space the bottle itself occupies). In practice, "volume" is used for both in everyday contexts.
- How do I calculate volume from dimensions?
- For rectangular containers: Volume = Length × Width × Height. Example: 20 cm × 10 cm × 5 cm = 1,000 cm³ = 1 liter (since 1 liter = 1,000 cm³). For cylinders: Volume = π × radius² × height. For example, a cylinder with 5 cm radius and 10 cm height: 3.1416 × 5² × 10 = 785.4 cm³ ≈ 0.785 liters. Ensure all dimensions use the same unit before calculating.
