Question 270General Subjects - 1st Asst/Chief

The correct answer is C) By multiplying the volume by the density of the fuel. To convert a volume measurement to a weight measurement, you need to know the density of the fuel. Density is the mass per unit volume of a substance, typically expressed in units of pounds per gallon or kilograms per liter. By multiplying the volume by the density, you can calculate the weight or mass of the fuel. The other options are incorrect because specific gravity is a dimensionless ratio that compares the density of a substance to the density of a reference material, typically water. Dividing by the specific gravity or density would not yield the correct weight conversion.
