The question, as stated, cannot be answered sensibly. A gallon is a measure of volume, with dimensions [L3]. A kilogram is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
As a simple mental exercise consider a gallon of air and of water. They will have very different masses.

This depends on the substance you are measuring. If you are measuring water:1 US gallon weighs 3.78541178 kg1 UK (Imperial) gallon weighs 4.54609118 kg
"Kg" is a unit of mass. "Gallon" is a volume of space. The gallon may be completely empty, with no mass in it. If the gallon of space has any mass at all in it, then the amount of mass depends on what substance is in the gallon.
The conversion of kilograms to gallons depends on what substance you are measuring. If you are referring to water, 1 gallon is approximately equal to 3.785 kilograms. Therefore, 250 kilograms would be roughly equivalent to 66 gallons of water.
Gallon is a unit of volume, Kg is a unit of weight (mass). 1 Gallon = 3.7854118 liters Considering a liter weighing 1 Kg (water for instance), then a gallon weighs 3.7854118 Kg. To convert from one to the other you will need to know what material is being converted and what temperature it is at. There is no universal conversion from gallons to kilograms.
