About Imperial gallon (imp gal)
The imperial gallon is a unit of volume defined as exactly 4.54609 liters, used in the United Kingdom, Canada, and some Commonwealth nations. It is approximately 20% larger than the US liquid gallon. Fuel economy in the UK is expressed in miles per imperial gallon. The imperial gallon divides into 8 imperial pints, each of 568 mL. The UK officially metricated fuel sales to liters in the 1980s–1990s, but miles per imperial gallon remains the legal unit for new car fuel economy labels.
UK car fuel economy figures are expressed in miles per imperial gallon. One imperial gallon equals 8 standard UK pints of beer.
About Milliliter (ml)
A milliliter (mL) is one thousandth of a liter (0.001 L), exactly equal to one cubic centimeter (1 cm³). It is the most widely used small volume unit in medicine, cooking, and science. Drug dosages are prescribed in milliliters, soft drink cans are 330 mL, and laboratory pipettes measure in mL. The milliliter bridges the gap between the impractically small microliter and the everyday liter, making it the default unit for liquid measurement in clinical and domestic settings worldwide.
A standard medicine syringe holds 1–20 mL. A teaspoon is approximately 5 mL. A typical espresso shot is 30 mL.
Etymology: From Latin "mille" (thousand) + "liter". The prefix milli- denotes 10⁻³ in the SI system.
Imperial gallon – Frequently Asked Questions
How many liters are in an imperial gallon?
One imperial gallon is defined as exactly 4.54609 liters — approximately 20% more than the US liquid gallon (3.785 L).
Does the UK still use gallons?
The UK switched fuel sales to liters in the 1990s. However, miles per gallon (imperial) remains the legal unit for car fuel economy on new vehicle labels. Road speed is in mph and distances are in miles, so imperial gallons remain embedded in UK motoring.
How does UK MPG differ from US MPG?
UK MPG uses the imperial gallon (4.546 L); US MPG uses the US gallon (3.785 L). Multiply UK MPG by 0.832 to get US MPG. A car rated 40 UK MPG ≈ 33 US MPG.
How many pints are in an imperial gallon?
There are exactly 8 imperial pints in one imperial gallon. Each imperial pint is 568 mL, compared to 473 mL for a US pint.
Is the imperial gallon still used in Canada?
Canada officially metricated in the 1970s and fuel is sold in liters. However, some older Canadians and certain agricultural contexts still reference imperial gallons informally. Canadian and UK imperial gallons are identical (4.54609 L).
Milliliter – Frequently Asked Questions
How many milliliters are in a teaspoon?
One US teaspoon equals approximately 4.93 mL, conventionally rounded to 5 mL in cooking and medicine. An Australian/metric teaspoon is exactly 5 mL. A tablespoon is 15 mL (3 teaspoons).
Why do medicine bottles say "do not use household spoons" for dosing?
Household teaspoons and tablespoons vary wildly — from 3 to 7 mL for a "teaspoon" depending on the design. A parent dosing 2.5 mL of infant paracetamol with a large decorative spoon might accidentally give double the intended dose. Studies have shown dosing errors of 20–50% when using kitchen cutlery. Calibrated oral syringes (marked in 0.1 mL increments) eliminate this problem entirely, which is why the AAP and WHO both recommend them over any spoon for liquid medications.
How many milliliters are in a standard drink can?
A standard soft drink or beer can is typically 330 mL in Europe and 355 mL (12 US fl oz) in the United States. A 500 mL can is common for beer in many markets.
What is a standard medical dose in mL?
Common oral liquid medications are dosed at 2.5, 5, or 10 mL. Injectable medications may be 0.1–2 mL. IV fluid bags are typically 100, 250, 500, or 1,000 mL.
How many milliliters are in a fluid ounce?
One US fluid ounce equals approximately 29.57 mL. One imperial (UK) fluid ounce equals approximately 28.41 mL. The two are close but not identical — important for recipes crossing US and UK sources.
