At a supplied density of 1,000 kg/m³, 250 cm³ has mass 250 g. At 2,000 kg/m³, the same volume has mass 500 g.

Mass (g) = density (kg/m³) × volume (cm³) ÷ 1,000

Enter these known values and leave the other values blank.

One cubic centimeter is exactly one milliliter. A gram is a unit of mass, so converting grams to cc requires a density.
The model requires positive mass, density and volume and assumes the supplied density applies to the sample.
The example density is illustrative. No water-density value or other material property is automatically assumed. Temperature, pressure and packing may change the applicable density.

No. Their numerical values coincide only when density is 1 g/cm³. They measure different physical quantities.

A gram is 0.001 kg and a cubic centimeter is 0.000001 m³. Dividing those conversion factors gives 1,000 kg/m³.

Bookify uses exact customary mass and volume definitions for density units, replacing rounded factors in the reference.
