Do you mean the Earth's crust? If so, typical densities are:
- Continental crust (average): ≈ 2.7 g/cm³ (2700 kg/m³)
- Upper continental crust: ≈ 2.6 g/cm³ (2600 kg/m³)
- Lower continental crust: ≈ 2.8–3.1 g/cm³ (2800–3100 kg/m³)
- Oceanic crust (basaltic/gabbroic): ≈ 2.8–3.0 g/cm³ (2800–3000 kg/m³)
Overall crustal rock densities commonly range roughly 2.2–3.3 g/cm³ depending on lithology (sediments, granites, basalts, etc.) and depth.
If you meant a different crust (e.g., lunar, Martian, or a food crust), tell me which and I’ll give the relevant values.
