How many gallons are in 5.5 kilograms?

Answer 1

That depends on what kind of substance occupies the 55 gallons of space.
If it's 55 gallons of air, then there are very few kilograms of mass in it.
If it's 55 gallons of water, then its mass is about 208 kilograms.
If it's 55 gallons of granite, then its mass is a lot more than 208 kilograms.
If the 55 gallons of space is empty, then there are no (zero) kilograms of mass in it.

Answer 2

To convert kilograms to gallons, you need to know the density of the substance you are measuring. Once you have the density, you can use the formula: volume (gallons) = mass (kg) / density (kg/gallon). Without knowing the density, it is not possible to give an accurate conversion from kilograms to gallons.

Answer 3

A gallon is a unit of capacity. A kilogram is a unit of mass. The two units are therefore incompatible.

Answer 4

Kilograms is a measure of weight and gallons a unit of volume. You cannot directly convert between the two.
