About Converting Pounds per Imperial gallon to Grams per Milliliter
Pound per Imperial gallon and Gram per Milliliter both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
grams per milliliter = pounds per imperial gallon × 0.0997763726631
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 gram per milliliter equals 1000 base units, so dividing one by the other gives the direct pound per imperial gallon-to-gram per milliliter factor of 0.0997763726631.
Simple example
1 lb/imp gal × 0.09977637266 = 0.0997763727 g/mL
1 pound per imperial gallon = 0.0997763727 grams per milliliter.
Real-world example
1,000 lb/imp gal × 0.09977637266 = 99.77637266 g/mL
1,000 pounds per imperial gallon = 99.77637266 grams per milliliter.

Frequently asked questions
How many grams per milliliter are in 1 pound per imperial gallon?
1 pound per imperial gallon equals 0.0997763727 grams per milliliter, using the exact defined conversion factor rather than an estimate.
How do I convert pound per imperial gallon to gram per milliliter?
Multiply the pound per imperial gallon value by 0.09977637266. The converter above does this instantly to whatever precision you set.
How do I convert gram per milliliter back to pound per imperial gallon?
Use the reverse factor: 1 gram per milliliter equals 10.02241285 pounds per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per imperial gallon?
Pound per Imperial gallon (lb/imp gal) is a unit of density.
What is a gram per milliliter?
Gram per Milliliter (g/mL) measures density. Numerically identical to grams per cubic centimeter and to kilograms per liter, since one milliliter equals one cubic centimeter exactly. It is classified as a metric derived density unit.
Is the pound per imperial gallon to gram per milliliter conversion exact?
Yes. Numerically identical to grams per cubic centimeter and to kilograms per liter, since one milliliter equals one cubic centimeter exactly. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
