What Is A Liter?
A liter is a metric unit of measurement that defines the volume of one kilogram of water at a temperature of 4 degrees Celsius.
One litre (as spelled in British English) is equivalent to 0.264 U.S. gallons or 0.22 Imperial gallons. It is a widely recognized unit of volume measurement used globally to measure liquids such as gasoline, milk, water, and juice, as well as fluids (liquids and gases) in scientific and engineering fields.
What is A Gallon?
A gallon is a unit of measurement of the volume of liquid in U.S. Customary units and Imperial units (links out to Wikipedia pages). There are three types of gallon measurements.
- Imperial gallon - This unit of measurement of volume is used in countries such as the U.K., Canada, Australia, New Zealand, and some nations in the Caribbean Islands.
- US gallon - A standard unit of measuring the volume of liquid in the U.S., as well as in several Latin American countries and a few Caribbean Islands nations.
- US dry gallon - Though not currently in use, this was historically used as a unit of measuring the volume of grains such as corn and wheat, as well as other dry commodities. One US dry gal = ⅛ US Bushel.
What is Imperial Gallon?
Imperial gallon is based on the volume of 10 pounds (i.e., 4.536 kilograms) of water at a temperature of 62 °F (17 °C). It is used as a unit of volume measurement in the United Kingdom and some other Commonwealth countries. Thus 1 Imperial Gallon equals 4.546 liters of water. It is about 20% larger than US liquid gallon (i.e., 1 Imperial Gallon = 1.20 US liquid gallon).
What is US Liquid Gallon?
The US Liquid Gallon (referred commonly as US Gallon) is a volume of 231 cubic inches. At 4 degrees celcius this volume can contain 3.7854 kilogram of water. Thus 1 US liquid gallon equals 3.7854 litres of water at 4 degrees celcius. When compared to Imperial gallon, US liquid gallon is about 16.7% less in volume.
What is US Dry Gallon?
The US Dry Gallon is a volume measurement unit for grains (such as corn, soy beans, and wheat) and other dry commodities. Though this is not widely used in practice, you will still come across its mention since it is connected to the common measurement unit of Bushel. One US dry gallon equals ⅛ Bushel. In numeric terms, 1 US dry gallon equals 268.8 cubic inches (i.e., 1 US dry gallon = 4.404 liters of water).
Thus US liquid gallon is about 14.1% less than US dry gallon, whereas Imperial liquid Gallon is 3.2% larger than US dry gallon.
Conversion Table: US Gallon to Liters and Imperial Gallon to Liters
| Gallon Measurement | US Gallon to Liters | UK Gallon to Liters |
|---|---|---|
| 1 gallon | 3.785 | 4.546 |
| 2 gallons | 7.57 | 9.092 |
| 3 gallons | 11.355 | 13.638 |
| 4 gallons | 15.14 | 18.184 |
| 5 gallons | 18.925 | 22.73 |
The above conversion chart is especially useful when dealing with large volumes of liquids. For example, a tourist may be interested to know how many liters of gasoline (petrol/diesel) was filled up in the fuel tank at a gas station.
Suppose 5 gallon of gasoline was filled up at a gas station in the USA, then this conversion guide immediately allows one to know 18.925 liters of fuel was topped up in the tank.
If you were in UK, and the fuel station reads 5 gallons, then it means 22.73 litres of gasoline was added to the fuel tank of your vehicle.
Conversion from US Gallon to Other Volume Measurements
When dealing with larger volumes of liquids it is useful to know how to convert between US Gallon measurement to other common and popular units of volume meaurement such as Quart, Pint, and Cups. This conversion table will be especially useful in large restaurant kitchens, catering kitchens, and community kitchens.
| US Gallon Measurement | US Gallon to Liters | US Gallon to Quart | US Gallon to Pint | US Gallon to Cup |
|---|---|---|---|---|
| 1 gallon | 3.785 | 4 | 8 | 16 |

Bonus - Popular Liquid Volume Conversions in the Kitchen
Volume measurements in US cups are more commonly used in recipes due to the smaller quantities typically cooked at home compared to a restaurant. Thus the below table may be extremely useful for home cooks (irrespective of your expertise) to convert liquid volume measurements between US cups, Teaspoon (tsp), Tablespoon (tbsp), Milliliters (ml), and Fluid Ounces (fl oz).
I have personally printed and laminated this liquid volume conversion table on a cardstock paper and kept it handy in my kitchen for quick and easy reference.
| US Cups | Teaspoons (tsp) | Tablespoons (tbsp) | Milliliters (ml) | Fluid Ounces (fl oz) |
|---|---|---|---|---|
| 1/16 | 3 | 1 | 15 | 0.5 |
| ⅛ | 6 | 2 | 30 | 1 |
| ¼ | 12 | 4 | 60 | 2 |
| ⅓ | 16 | 5 ⅓ | 80 | 2.67 |
| ½ | 24 | 8 | 120 | 4 |

In the US, 1 gallon equals 128 fluid ounces. 1 Imperial/UK gallon = 160 Imperial/UK fluid ounces in the UK.
In the US, 1 gallon of liquid equals 16 US cups. Similarly, 1 Imperial/UK gallon of fluid = 16 Imperial/UK cups.
In the US, 1 gallon of liquid equals 8 US pints. Similarly, 1 Imperial/UK gallon of fluid = 8 Imperial/UK pints.
1 US gallon of liquid = 4 US quarts of liquid. Similarly, 1 Imperial/UK gallon of liquid = 4 Imperial/UK quarts.
In Australia, 1 Gallon of a liquid equals 4.546 litres. This is the same as the UK.
In Canada, 1 Gallon of a liquid equals 4.546 litres. This is the same as the UK.
However, since 1970 many units of measurement, including the volume of liquids have moved to the metric system. Thus you will find that in Canada, gasoline, milk, and water are sold in litres, however, some beverages like coffee are sold in fluid ounces.
In the UK, 1 Gallon of a liquid equals 4.546 litres.
