About Converting Grams per Cup to Troy ounces per Cubic Millimeter
Gram per Cup and Troy ounce 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
troy ounces per cubic millimeter = grams per cup × 1.358933e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cup equals 4.22675283773 base units, and 1 troy ounce per cubic millimeter equals 31103476.8 base units, so dividing one by the other gives the direct gram per cup-to-troy ounce per cubic millimeter factor of 1.358933e-7.
Simple example
1 g/cup × 1.358933e-7 = 1.358933e-7 oz t/mm3
1 gram per cup = 1.358933e-7 troy ounces per cubic millimeter.
Real-world example
1,000 g/cup × 1.358933e-7 = 0.0001358933 oz t/mm3
1,000 grams per cup = 0.0001358933 troy ounces per cubic millimeter.

What is a gram per cup?
Gram per Cup (g/cup) is a unit of density.
What is a troy ounce per cubic millimeter?
Troy ounce per Cubic Millimeter (oz t/mm3) is a unit of density.
Is the gram per cup to troy ounce per cubic millimeter conversion exact?
Yes. Both gram per cup and troy ounce per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 1.358933e-7 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.
