About Converting Grams per Cubic Millimeter to Ounce per Cubic inches
Gram per Cubic Millimeter and Ounce per Cubic inch 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
ounce per cubic inches = grams per cubic millimeter × 578.036672001
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic millimeter equals 1000000 base units, and 1 ounce per cubic inch equals 1729.99404439 base units, so dividing one by the other gives the direct gram per cubic millimeter-to-ounce per cubic inch factor of 578.036672001.
Simple example
1 g/mm3 × 578.036672 = 578.036672 oz/in3
1 gram per cubic millimeter = 578.036672 ounce per cubic inches.
Real-world example
1,000 g/mm3 × 578.036672 = 578,036.672 oz/in3
1,000 grams per cubic millimeter = 578,036.672 ounce per cubic inches.

Frequently asked questions
How many ounce per cubic inches are in 1 gram per cubic millimeter?
1 gram per cubic millimeter equals 578.036672 ounce per cubic inches, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic millimeter to ounce per cubic inch?
Multiply the gram per cubic millimeter value by 578.036672. The converter above does this instantly to whatever precision you set.
How do I convert ounce per cubic inch back to gram per cubic millimeter?
Use the reverse factor: 1 ounce per cubic inch equals 0.001729994 grams per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per cubic millimeter?
Gram per Cubic Millimeter (g/mm3) is a unit of density.
What is a ounce per cubic inch?
Ounce per Cubic inch (oz/in3) is a unit of density.
Is the gram per cubic millimeter to ounce per cubic inch conversion exact?
Yes. Both gram per cubic millimeter and ounce per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 578.036672 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.
