About Converting Ounces per Cup to Grams per Cubic Millimeter
Ounce per Cup and Gram 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
grams per cubic millimeter = ounces per cup × 0.000119826427317
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cup equals 119.826427317 base units, and 1 gram per cubic millimeter equals 1000000 base units, so dividing one by the other gives the direct ounce per cup-to-gram per cubic millimeter factor of 0.000119826427317.
Simple example
1 oz/cup × 0.0001198264273 = 0.0001198264 g/mm3
1 ounce per cup = 0.0001198264 grams per cubic millimeter.
Real-world example
1,000 oz/cup × 0.0001198264273 = 0.1198264273 g/mm3
1,000 ounces per cup = 0.1198264273 grams per cubic millimeter.

Frequently asked questions
How many grams per cubic millimeter are in 1 ounce per cup?
1 ounce per cup equals 0.0001198264 grams per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per cup to gram per cubic millimeter?
Multiply the ounce per cup value by 0.0001198264273. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic millimeter back to ounce per cup?
Use the reverse factor: 1 gram per cubic millimeter equals 8,345.404452 ounces per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per cup?
Ounce per Cup (oz/cup) is a unit of density.
What is a gram per cubic millimeter?
Gram per Cubic Millimeter (g/mm3) is a unit of density.
Is the ounce per cup to gram per cubic millimeter conversion exact?
Yes. Both ounce per cup and gram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.0001198264273 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.
