FAQ
-
What is the difference between a US gallon and an Imperial gallon?
A US gallon equals 3,785.41 mL while an Imperial gallon equals 4,546.09 mL. The Imperial gallon is about 20% larger. This difference traces back to historical measurement standards — the US adopted the older English wine gallon, while the UK later standardized the Imperial gallon based on the volume of 10 pounds of water.
-
Why are US and Imperial fluid ounces different sizes?
A US fluid ounce is 29.5735 mL and an Imperial fluid ounce is 28.4131 mL. Despite the Imperial ounce being smaller, an Imperial pint contains 20 fluid ounces (568.26 mL) compared to the US pint with 16 fluid ounces (473.18 mL), making the Imperial pint larger overall.
-
Is a milliliter the same as a cubic centimeter?
Yes, 1 mL equals exactly 1 cm³. This equivalence was established by definition — the liter was originally defined as the volume of 1 kilogram of water, which occupies 1,000 cubic centimeters. While there was a brief historical discrepancy, the modern definition makes them precisely equal.
-
How do cooking measurements relate to standard volume units?
US cooking measurements follow the customary system: 1 teaspoon = 4.929 mL, 1 tablespoon = 3 teaspoons = 14.787 mL, and 1 US cup = 16 tablespoons = 236.588 mL. Note that metric, Australian, and Japanese cups differ (250 mL), so always check which standard a recipe uses.
