A milliliter is a metric unit of volume used around the world for measuring small amounts of liquid. It's abbreviated as mL and is defined as one-thousandth of a liter—making it ideal for precise, everyday measurements. One milliliter is equal to 1 cubic centimeter (cm³) and roughly 0.034 fluid ounces (US).
Because of its precision and simplicity, the milliliter is a standard in science, medicine, cooking, and packaging. Whether you're reading a nutrition label, following a recipe, or measuring out a medication dose, the milliliter is a practical and widely accepted unit in both personal and professional settings.
Uses: The milliliter is used globally in a wide range of applications. In the kitchen, it helps measure small liquid quantities like vanilla extract, lemon juice, or oil. On food packaging, beverages, and household products, you'll often see volumes listed in milliliters to indicate serving sizes or total content.
In healthcare, the milliliter is critical for accurately dosing liquid medications, especially in syringes and measuring cups. The milliliter is often seen in labs and industries where accurate volume is expected. It’s also used on packaging, recipe cards, and medicine labels to keep measurements clear and consistent in everyday use.
The imperial gallon is a unit of volume used in the imperial measurement system, and it is historically common in the United Kingdom and several other countries. One imperial gallon is equal to 4.54609 liters, which makes it significantly larger than the US gallon (approximately 3.785 liters). It is abbreviated as gal and traditionally used for measuring liquids in larger quantities.
In the imperial system, a gallon is made up of four quarts, eight pints, or 160 imperial fluid ounces. Though the UK has officially adopted the metric system, the imperial gallon is still recognized in specific contexts and remains part of British measurement history. It's most commonly associated with fuel pricing and older food or drink packaging.
Uses: The imperial gallon is most commonly seen today at fuel stations in the UK, where petrol and diesel are still sold by the gallon for pricing comparisons, even though the actual quantity delivered is measured in liters. Historically, the gallon was used for everything from milk deliveries to beer and cider sales.
While modern recipes and packaging have largely shifted to liters and milliliters, the imperial gallon occasionally appears in traditional instructions or product specs, especially for bulk liquids. For those referencing older materials or converting classic measurements, the imperial gallon remains a useful and historically significant unit.
1 mL = 0.00022 gal (imp)
Let’s say you want to convert 100 mL to gal (imp).
Using the formula:
100 × 0.00022 = 0.022 gal (imp)
So, 100 mL is approximately 0.022 gal (imp).
