what is the density of steel
The density of steel is typically around 7.8–7.9 grams per cubic centimeter (g/cm³), which is about 7,850–7,900 kilograms per cubic meter (kg/m³).
Since you asked for a structured “Quick Scoop”, here’s a compact breakdown.
Basic value (short answer)
- Most general-purpose or mild steels: ≈ 7.85 g/cm³.
- In SI units: ≈ 7,850 kg/m³.
- In imperial units: ≈ 490 lb/ft³.
Why it’s a range, not one exact number
Steel is an alloy, so its exact density depends on composition and treatment.
- Typical range for common steels: 7.75–8.05 g/cm³ (7,750–8,050 kg/m³).
- Stainless steels tend to be near the upper end, often close to 8,000 kg/m³.
- Low/medium/high carbon steels are frequently taken as 7.85 g/cm³ in engineering handbooks and weight calculators.
Mini example
If you have a solid steel block of 0.01 m³ (10 liters), using 7,850 kg/m³ gives a mass of:
- 7,850 kg/m³×0.01 m³=78.5 kg7,850\text{ kg/m³}\times 0.01\text{ m³}=78.5\text{ kg}7,850 kg/m³×0.01 m³=78.5 kg.

Tiny “story” to remember it
Engineers often remember steel by comparison: aluminum is roughly one-third as dense and titanium about half as dense, so if you know aluminum is near 2.7 g/cm³, tripling that gets you close to steel at about 7.8–7.9 g/cm³.
TL;DR: For most practical calculations, using 7.85 g/cm³ (7,850 kg/m³) as the density of steel is accurate enough unless you are working with a specialized alloy that specifies otherwise.
