One tonne of water equals slightly more than 240 gallons. A tonne is equal to 2,000 pounds, while a gallon contains 8.33 pounds; a gallon measures the liquid volume of a substance, whereas a tonne measures its actual mass.
To determine how many gallons are in one tonne of water, it is necessary to know how many pounds are in a gallon. Since there are 8.33 pounds in a gallon and 2,000 pounds in a tonne, the equation is as straightforward as dividing 2,000 by 8.33. The answer will vary based on the type and volume of liquid being measured; a tonne of a substance with a greater viscosity will frequently measure very differently than a tonne of water.
It is important to note that the gallons and tonnes used in these equations are examples from the United States. The metric system also includes measurements for a gallon and a tonne, but these are slightly different from their U.S. counterparts. Gasoline is the most common liquid in the United States that uses the conversion from gallons to tonnes. It is purchased commercially by the tonne and then sold to consumers by the gallon for use in automobiles.
