Gallons to Grams Conversion

To perform the gallons to grams conversion, we rely on the widely known formula to calculate mass from density and volume:

Mass = Density × Volume

We must use the correct units in this formula. Below we explain a convenient way to do it.

Gallons to grams conversion

The easiest way to convert from gal to g is to multiply the density in grams per gallon (g/gal) by the number of gallons (the volume of substance):

Mass [g] = Density [g/gal] × Volume [gal]

Grams to gallon conversion

To convert from grams to gallons, divide the mass in grams by the density in g/gal:

Volume [gal] = Mass [g]/Density [g/gal]

Expressing density as grams per gallon

The most probable scenario when converting gal to g is that you don't know the density in grams per gallon but in other units. Don't worry! Here are some conversion factors to go from those units to grams per US gallon:

• Density [g/gal] = Density [kg/m³] × 3.78541;
• Density [g/gal] = Density [g/cm³] × 3,785.41;
• Density [g/gal] = Density [g/mL] × 3,785.41;
• Density [g/gal] = Density [lb/in³] × 104,780;
• Density [g/gal] = Density [lb/gal] × 453.592.

For example, if the density is in kg/m³, multiply it by 3.78541 and that will be the density in g/gal (US)
