About Converting Grams per Fluid ounce to Pounds per Cubic Millimeter
Gram per Fluid ounce and Pound per Cubic Millimeter 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
pounds per cubic millimeter = grams per fluid ounce × 7.454716e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per fluid ounce equals 33.8140227018 base units, and 1 pound per cubic millimeter equals 453592370 base units, so dividing one by the other gives the direct gram per fluid ounce-to-pound per cubic millimeter factor of 7.454716e-8.
Simple example
1 g/fl oz × 7.454716e-8 = 7.454716e-8 lb/mm3
1 gram per fluid ounce = 7.454716e-8 pounds per cubic millimeter.
Real-world example
1,000 g/fl oz × 7.454716e-8 = 0.0000745472 lb/mm3
1,000 grams per fluid ounce = 0.0000745472 pounds per cubic millimeter.

What is a gram per fluid ounce?
Gram per Fluid ounce (g/fl oz) is a unit of density.
What is a pound per cubic millimeter?
Pound per Cubic Millimeter (lb/mm3) is a unit of density.
Is the gram per fluid ounce to pound per cubic millimeter conversion exact?
Yes. Both gram per fluid ounce and pound per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 7.454716e-8 used above is exact to as many digits as you choose to display.
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.
