Conversion Formula
$$SG = kg/m³ \times 0.001$$
Multiply the value in Kilogram per Cubic Meter by 0.001 to get Specific Gravity.

kg/m³ to SG in Engineering
Density conversions are critical for fluid mechanics, material selection, concrete mix design, and petroleum engineering. Specific gravity (relative to water at 4°C) is commonly used as a dimensionless density ratio across all disciplines.
Kilogram per Cubic Meter: SI unit of density. Water at 4°C has a density of approximately 1000 kg/m³.
Specific Gravity: Dimensionless ratio of density to water at 4°C (1000 kg/m³). SG = 1.0 for water. Universal engineering reference.
