Convert Milliliter to UK Gallon (ml → gal (UK))

Converting milliliters to UK gallons is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in milliliters

   Start with the number of milliliters (ml) you want to convert.
2. 2
   Multiply by 0.00022

   The conversion factor from ml to gal (UK) is 0.00022. Multiply your value by this number.
3. 3
   Read the result in UK gallons

   The result is your value in UK gallons (gal (UK)).

Multiply the value in milliliters by 0.00022. For the reverse direction, multiply by 4,546.09.

• ✓1 ml = 1 cm³ exactly.
• ✓Medicine: teaspoon ≈ 5 ml, tablespoon ≈ 15 ml, shot glass ≈ 25 ml.
• ✓Measuring jugs marked in ml provide 2–5 ml accuracy; use a syringe below 10 ml.

• ✗Dosing liquid medication by kitchen spoon — spoons vary 3–8 ml. Use the supplied syringe.
• ✗Confusing ml (volume) with mg (mass) on medication labels — different units entirely.
• ✗Reading a "cc" measurement as cubic centimetre with different value — it is identical to ml.

What is the Milliliter?

The milliliter equals one thousandth of a liter (0.001 L) and is the standard small-volume unit for cooking, pharmaceuticals, cosmetics, and laboratory work. One milliliter is exactly 1 cubic centimeter (1 cm³), a convenient relationship: 1 mL of pure water weighs 1 gram. The milliliter is the universal unit on medicine bottles (a typical cough syrup dose is 5 mL), cosmetics (a perfume bottle is 50–100 mL), and recipe measurements outside North America (a tablespoon is 15 mL, a teaspoon is 5 mL). Medical syringes are calibrated in mL, and IV drip rates are computed in mL per hour. The milliliter relates to the liter (1,000 mL = 1 L), the cubic centimeter (1 mL = 1 cm³ = 1 cc), the teaspoon (1 tsp = 5 mL), and the US fluid ounce (1 fl oz ≈ 29.57 mL).

• Precise cooking and baking measurements
• Laboratory reagent measurement

What is the UK Gallon?

The UK imperial gallon equals exactly 4.54609 liters and is approximately 20% larger than the US gallon. Established by the British Weights and Measures Act of 1824 to standardize earlier ale and corn gallons, the imperial gallon was designed so that 10 pounds of pure water at 62°F occupied exactly 1 gallon. Although the United Kingdom has officially adopted the liter for fuel sales since 1995, the imperial gallon persists in everyday speech ('miles per gallon' for car fuel economy) and remains the standard unit in some Caribbean and Pacific Commonwealth countries. The imperial gallon relates to the US gallon (1 imp gal ≈ 1.201 US gal), the imperial quart (4 imp qt = 1 imp gal), the imperial pint (8 imp pt = 1 imp gal — the famous British pint of beer), and the liter (1 imp gal ≈ 4.546 L).

• Older British industrial and brewing contexts
• Commonwealth countries that retain imperial measures
