Gallon to Tons Converter: Gallons to Tons Weight Calculator
Convert gallons to metric tons, kilograms, US tons, long tons and pounds in seconds. This free gallon to tons calculator converts US gallons (3.78541 L) and imperial gallons (4.54609 L) to weight using liquid density. The gallons to tons calculator below (also a gallons to tons converter) needs only three inputs: the volume in gallons, the liquid (water, seawater, milk, vegetable oil, crude oil, motor oil, diesel, gasoline, kerosene, ethanol) or a custom kg/L value, and the gallon type. It also works in reverse: enter metric tons to get gallons. A quick gallon to ton table and a full liquid density chart are included for reference.
Gallon to tons calculator
Formula: kilograms = gallons x liters per gallon x density, then metric tons = kilograms / 1000. One US gallon of water is exactly 3.78541 kg.

Real-world context
Fuel, water, and milk are bought by the ton but measured and shipped by the gallon, which is exactly why a gallon to tonne calculator is standard logistics equipment. Typical conversions to keep on hand:
- A standard 55-gallon drum of diesel weighs 176.97 kg, or 0.17697 metric tons of liquid (the steel drum adds roughly 20 kg more).
- A 5,000 US gallon water tanker carries 18.92705 metric tons of water.
- A 9,000 imperial gallon road tanker of water is 40.9148 metric tons.
- One metric ton of water is 264.17 US gallons (219.97 imperial gallons); one metric ton of diesel at 0.85 kg/L is 310.79 US gallons.
- A US gallon is 3.78541 liters; an imperial gallon is 4.54609 liters, about 20.1 percent larger, so always confirm which gallon a quote uses.

Frequently asked questions
What is the formula to convert gallons to tons?
The formula is: metric tons = gallons x liters per gallon x density / 1000, where density is in kilograms per liter (kg/L). For a US gallon use 3.78541 liters per gallon. For example, 5 US gallons of diesel at 0.85 kg/L give 5 x 3.78541 x 0.85 = 16.088 kg, which is 0.016088 metric tons. For the reverse direction, gallons = metric tons x 1000 / density / liters per gallon.
How many tons is a gallon of water?
One US gallon of water weighs 0.00378541 metric tons (3.78541 kg, or 8.3454 lb). One imperial gallon of water weighs 0.00454609 metric tons (10.0224 lb) because the imperial gallon is larger at 4.54609 liters. In US short tons, one US gallon of water is 0.0041727 tons.
How many tons is 100 gallons of water?
100 US gallons of water weigh 0.378541 metric tons. That is 378.541 kg. For 100 imperial gallons of water the weight is 0.454609 metric tons.
How many tons is 1000 gallons of water?
1000 US gallons of water weigh 3.78541 metric tons. That is 3785.41 kg, or about 4.1727 US short tons.
How many tons is a gallon of diesel?
One US gallon of diesel weighs 0.0032176 metric tons at the typical diesel density of 0.85 kg/L. Diesel density varies between about 0.82 and 0.86 kg/L with temperature and grade, so use your fuel data sheet for exact work.
How much does 55 gallons of diesel weigh?
55 US gallons of diesel weigh 176.97 kg, which is 0.17697 metric tons, at 0.85 kg/L. A standard 55-gallon drum is the classic example: the drum itself adds roughly 20 kg of steel on top of the liquid.
How much does a gallon of gasoline weigh?
One US gallon of gasoline weighs 2.8012 kg (6.1756 lb) at the typical density of 0.74 kg/L, which is 0.0028012 metric tons. Gasoline is lighter than water, so it floats: the same gallon of water weighs 3.78541 kg.
How much does a gallon of milk weigh?
One US gallon of milk weighs 3.899 kg (8.5958 lb) at the typical density of 1.03 kg/L. Milk is slightly denser than water because of its dissolved solids and fat content.
What is the difference between a US gallon and an imperial gallon?
A US gallon is 3.78541 liters (231 cubic inches) and an imperial gallon is 4.54609 liters. The imperial gallon is about 20.1 percent larger. Always check which gallon a recipe, fuel quote, or shipping document means: one imperial gallon of water weighs 0.00454609 metric tons versus 0.00378541 for a US gallon.
How do I convert gallons to US tons?
Compute kilograms first (gallons x liters per gallon x density), then divide by 907.18474 to get US short tons. For example, one US gallon of water is 3.78541 kg, which is 3.78541 / 907.18474 = 0.0041727 US tons. A metric ton is about 10.2 percent heavier than a US ton, so check which ton your quote uses.
How many gallons are in a ton of water?
One metric ton of water is 264.17 US gallons (219.97 imperial gallons). For diesel at 0.85 kg/L, one metric ton is 310.79 US gallons, because the lighter liquid needs more volume for the same mass.
How do I use a custom density in this calculator?
Choose the Custom density option and type the density in kg/L from the liquid's data sheet or lab test. For example, a liquid at 1.20 kg/L gives 1 x 3.78541 x 1.20 = 4.5425 kg per US gallon, which is 0.0045425 metric tons. Custom densities are useful for syrups, brines, and chemical solutions that are not in the preset table.
How many tons is a gallon of vegetable oil?
One US gallon of vegetable oil weighs 0.0034826 metric tons (3.4826 kg) at the typical density of 0.92 kg/L. Cooking oils are all close to this value; motor oil at 0.89 kg/L is a touch lighter and crude oil at 0.88 kg/L lighter still.
Why does a gallon to tons converter need density?
Because gallons measure volume and tons measure mass, and density is the link between them. One US gallon of water weighs 0.00378541 metric tons, but one US gallon of gasoline weighs only 0.0028012 metric tons: same volume, different mass. Without density there is no correct answer.
