Frequently Asked Questions
What's the difference between US and Imperial gallons?
A US gallon equals 3.785 liters, while an Imperial (UK) gallon equals 4.546 liters. The Imperial gallon is about 20% larger. Most countries that use gallons today use the US measurement.
How many cups are in a liter?
There are approximately 4.227 US cups in one liter. This conversion is particularly useful for cooking when adapting international recipes that use metric measurements to US kitchen tools.
Why do cooking measurements vary between countries?
Different countries developed their measurement systems independently. The US uses customary units (cups, fluid ounces), while most other countries use metric (milliliters, liters).
How accurate should volume measurements be for cooking?
For most cooking, being within 5-10% is fine. However, baking requires more precision - especially for liquids and leavening agents. When converting, round to practical amounts rather than using exact decimal conversions.
What are the common volume conversion formulas?
Key conversions: 1 US gallon = 3.785 L, 1 cup = 236.59 mL, 1 fl oz = 29.57 mL, 1 tbsp = 14.79 mL, 1 tsp = 4.93 mL. These are essential for international recipe adaptation.
How do I convert between metric and US cooking units?
Use our converter for precision, or remember: 1 L ≈ 4.23 cups, 1 cup ≈ 237 mL, 1 tablespoon ≈ 14.8 mL. For baking, always use precise conversions as small differences can affect results.
