The two measurements are unrelated in that grams measures weight or mass and gallons measures volume. If the substance is known (i.e. water), a conversion can be made, but the density must be known.
Gallons can't be converted to grams. Gallons measure volume, while grams measure mass.
2-4 grams per litre. Approximately 38 - 76 grams for 5 gallons.
1,211,331.7696 grams
1211331.769 grams
Gallons can't be converted to milligrams. Gallons measure volume, while milligrams measure mass.
The answer is 2.
If its water you are talking about then 1 gallon equals 8.34 pounds. There are 16 oz's in a pound, therefore there are 133.44 oz's. And from being a pothead, I know there are 28.35 grams in an oz. Therefore there are 3783 grams of water in 5 gallons. [note: The above information is correct UNTIL the last line. If you do the math... there are 3783 grams of water in 1 gallon. Multiply by 5... gives 18,915 grams in 5 gallons. km]
18g is a little over 1/2 Oz.
"Gram" is a mass. "Gallon" is a volume of space. The number of grams of mass in 1.03 gallons of space depends on what substance you poured in there. If the gallon is empty, then there are no grams of mass at all in it.

There are 8 quarts in 2 gallons.
