Volume Conversion Formulas
Liters to US Gallons
US gallons = liters ÷ 3.78541Example: 10 liters = 10 ÷ 3.78541 = 2.642 US gallons
Milliliters to Fluid Ounces
fl oz = ml ÷ 29.5735Example: 250 ml = 250 ÷ 29.5735 = 8.454 fl oz
Cups to Milliliters
ml = cups × 236.588Example: 2 cups = 2 × 236.588 = 473.176 ml

Understanding Volume Measurements
US vs UK Gallons
The US gallon (3.785 liters) is smaller than the UK gallon (4.546 liters). This difference dates back to different measurement standards adopted in the 19th century. Always specify which gallon you're using to avoid confusion.
Volume vs Weight
Volume measures space (how much room something takes), while weight measures mass. For liquids like water, 1 liter weighs 1 kilogram, but this varies for other substances. Volume is easier for liquids, while weight is more accurate for dry ingredients in cooking.
Cooking Measurements
Cooking uses both volume (cups, tablespoons) and weight (grams, ounces) measurements. Volume is easier for liquids, while weight is more accurate for dry ingredients. Professional bakers prefer weight measurements for precision.
Volume Conversion Tips
- 1 US gallon = 3.785 liters (memorize this for fuel calculations)
- For cooking, 1 cup = approximately 240 ml (close enough for most recipes)
- 1 tablespoon = 15 ml, 1 teaspoon = 5 ml (standard cooking measurements)
- When converting fuel economy, remember: 1 L/100km = 235.21 MPG
- For precise measurements, use weight (grams) instead of volume for dry ingredients
