When to use this converter
A recipe lists liquid ingredients in cups or fluid ounces but your measuring equipment is marked in milliliters and you need to verify the right amount before pouring.
You are buying a beverage, fuel, or cleaning product sold in liters and want to understand the equivalent in gallons for comparison with a US price or package.
You are scaling a recipe up or down and need to convert tablespoons to milliliters or cups to get exact measurements for larger or smaller batches.
A product specification or medical instruction gives a volume in a unit your measuring tool does not display, and you need the equivalent before dispensing.
Common problems and fixes
The gallon result does not match what I expected from a US source.
This converter uses US gallons (3.785 liters). The imperial gallon used in the UK and some other countries is larger at 4.546 liters. If your source uses imperial gallons, the result will differ.
Teaspoons and tablespoons give unexpected results.
This converter uses US teaspoons (approximately 4.93 mL) and US tablespoons (approximately 14.79 mL). UK metric teaspoons and tablespoons differ slightly. Use the milliliter values as the common reference when precision matters.
I need to convert cubic centimeters or cubic inches.
One milliliter equals one cubic centimeter (cc), so you can use the milliliter unit for cc values directly. Cubic inches are not listed — one cubic inch equals approximately 16.39 mL.
