About Converting Nanograms per Cubic Millimeter to Gram per Cubic inches
Nanogram per Cubic Millimeter and Gram 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
gram per cubic inches = nanograms per cubic millimeter × 0.000016387064
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per cubic millimeter equals 0.001 base units, and 1 gram per cubic inch equals 61.0237440947 base units, so dividing one by the other gives the direct nanogram per cubic millimeter-to-gram per cubic inch factor of 0.000016387064.
Simple example
1 ng/mm3 × 0.000016387064 = 0.0000163871 g/in3
1 nanogram per cubic millimeter = 0.0000163871 gram per cubic inches.
Real-world example
1,000 ng/mm3 × 0.000016387064 = 0.016387064 g/in3
1,000 nanograms per cubic millimeter = 0.016387064 gram per cubic inches.

Frequently asked questions
How many gram per cubic inches are in 1 nanogram per cubic millimeter?
1 nanogram per cubic millimeter equals 0.0000163871 gram per cubic inches, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per cubic millimeter to gram per cubic inch?
Multiply the nanogram per cubic millimeter value by 0.000016387064. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic inch back to nanogram per cubic millimeter?
Use the reverse factor: 1 gram per cubic inch equals 61,023.74409 nanograms per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per cubic millimeter?
Nanogram per Cubic Millimeter (ng/mm3) is a unit of density.
What is a gram per cubic inch?
Gram per Cubic inch (g/in3) is a unit of density.
Is the nanogram per cubic millimeter to gram per cubic inch conversion exact?
Yes. Both nanogram per cubic millimeter and gram per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 0.000016387064 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.
