About Converting Grams per Fluid ounce to Milligrams per Cubic Millimeter
Gram per Fluid ounce and Milligram 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
milligrams per cubic millimeter = grams per fluid ounce × 0.0338140227018
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 milligram per cubic millimeter equals 1000 base units, so dividing one by the other gives the direct gram per fluid ounce-to-milligram per cubic millimeter factor of 0.0338140227018.
Simple example
1 g/fl oz × 0.0338140227 = 0.0338140227 mg/mm3
1 gram per fluid ounce = 0.0338140227 milligrams per cubic millimeter.
Real-world example
1,000 g/fl oz × 0.0338140227 = 33.8140227 mg/mm3
1,000 grams per fluid ounce = 33.8140227 milligrams per cubic millimeter.

Frequently asked questions
How many milligrams per cubic millimeter are in 1 gram per fluid ounce?
1 gram per fluid ounce equals 0.0338140227 milligrams per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per fluid ounce to milligram per cubic millimeter?
Multiply the gram per fluid ounce value by 0.0338140227. The converter above does this instantly to whatever precision you set.
How do I convert milligram per cubic millimeter back to gram per fluid ounce?
Use the reverse factor: 1 milligram per cubic millimeter equals 29.57352956 grams per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per fluid ounce?
Gram per Fluid ounce (g/fl oz) is a unit of density.
What is a milligram per cubic millimeter?
Milligram per Cubic Millimeter (mg/mm3) is a unit of density.
Is the gram per fluid ounce to milligram per cubic millimeter conversion exact?
Yes. Both gram per fluid ounce and milligram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.0338140227 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.
