Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.
Understanding the Units
What is a Gallon?
For large-batch cooking, 1 US gallon is approximately 3.8 liters. The imperial gallon (4.5 liters) is no longer commonly used in the UK for cooking, as most modern British recipes use metric measurements.
What is a Pound?
Pounds are the standard weight unit for buying ingredients in the US. A standard bag of flour is 5 pounds (2,268g) and a standard bag of sugar is 4 pounds (1,814g).

The most accurate way is to weigh water on a kitchen scale. If you are measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height. Liquids settle naturally, so volume measurements are already quite consistent.
Very close. Pure liquid densities are consistent across brands, so the gallons to pounds conversion for water typically varies by less than 2-3%.
For liquids like water, volume measurements are already quite accurate since liquids settle to a consistent level. A kitchen scale adds precision but the difference is typically small for liquid ingredients.
