About Converting Milligrams per Fluid ounce to Milligrams per Cubic Millimeter

Milligram 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 = milligrams per fluid ounce × 0.0000338140227018

This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per fluid ounce equals 0.0338140227018 base units, and 1 milligram per cubic millimeter equals 1000 base units, so dividing one by the other gives the direct milligram per fluid ounce-to-milligram per cubic millimeter factor of 0.0000338140227018.

Simple example

1 mg/fl oz × 0.0000338140227 = 0.000033814 mg/mm3

1 milligram per fluid ounce = 0.000033814 milligrams per cubic millimeter.

Real-world example

1,000 mg/fl oz × 0.0000338140227 = 0.0338140227 mg/mm3

1,000 milligrams per fluid ounce = 0.0338140227 milligrams per cubic millimeter.

Frequently asked questions

How many milligrams per cubic millimeter are in 1 milligram per fluid ounce?

1 milligram per fluid ounce equals 0.000033814 milligrams per cubic millimeter, using the exact defined conversion factor rather than an estimate.

How do I convert milligram per fluid ounce to milligram per cubic millimeter?

Multiply the milligram per fluid ounce value by 0.0000338140227. The converter above does this instantly to whatever precision you set.

How do I convert milligram per cubic millimeter back to milligram per fluid ounce?

Use the reverse factor: 1 milligram per cubic millimeter equals 29,573.52956 milligrams per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.

What is a milligram per fluid ounce?

Milligram per Fluid ounce (mg/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 milligram per fluid ounce to milligram per cubic millimeter conversion exact?

Yes. Both milligram per fluid ounce and milligram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.0000338140227 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.
