About Converting Kilograms per Cubic Meter to Grams per Cubic Centimeter
Kilogram per Cubic Meter and Gram per Cubic Centimeter 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. Kilogram per Cubic Meter is typically associated with universal — the official SI unit for density, used throughout physics and engineering worldwide, while Gram per Cubic Centimeter is typically associated with standard density unit in chemistry and materials science worldwide.
Formula
grams per cubic centimeter = kilograms per cubic meter × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic meter equals 1 base unit, and 1 gram per cubic centimeter equals 1000 base units, so dividing one by the other gives the direct kilogram per cubic meter-to-gram per cubic centimeter factor of 0.001.
Simple example
1 kg/m3 × 0.001 = 0.001 g/cm3
1 kilogram per cubic meter = 0.001 grams per cubic centimeter.
Real-world example
1,000 kg/m3 × 0.001 = 1 g/cm3
1,000 kilograms per cubic meter = 1 grams per cubic centimeter.
Conversion table
| Kilogram per Cubic Meter (kg/m3) | Gram per Cubic Centimeter (g/cm3) |
|---|---|
| 0.1 kg/m3 | 0.0001 g/cm3 |
| 1 kg/m3 | 0.001 g/cm3 |
| 10 kg/m3 | 0.01 g/cm3 |
| 100 kg/m3 | 0.1 g/cm3 |
| 1,000 kg/m3 | 1 g/cm3 |
| 10,000 kg/m3 | 10 g/cm3 |
Reverse conversion: Gram per Cubic Centimeter to Kilogram per Cubic Meter
0.001 g/cm3 × 1000 = 1 kg/m3
0.001 grams per cubic centimeter = 1 kilograms per cubic meter.
kilograms per cubic meter = grams per cubic centimeter × 1000

Understanding the Kilogram per Cubic Meter
Kilogram per Cubic Meter (kg/m3) measures density. The SI coherent unit for density — the form all other metric density/concentration units in this catalog are ultimately defined relative to. It is classified as a SI coherent derived unit.
Where it's used: Universal — the official SI unit for density, used throughout physics and engineering worldwide
kg/m³ vs. g/L vs. kg/L. All three are exactly related: 1 kg/m³ = 1 g/L, and 1,000 kg/m³ = 1 kg/L. kg/m³ is the formal SI-coherent form; g/L and kg/L are more commonly used in everyday and laboratory contexts.
Uses of the Kilogram per Cubic Meter today
- Physics and engineering reference density values
- Material property tables in scientific literature
- Fluid dynamics and structural engineering calculations
Understanding the Gram per Cubic Centimeter
Gram per Cubic Centimeter (g/cm3) measures density. Numerically identical to kilograms per liter, since one cubic centimeter equals one milliliter — this is the form most commonly used in chemistry and materials-science textbooks. It is classified as a metric derived density unit.
Where it's used: Standard density unit in chemistry and materials science worldwide
