1. What is EN9 Steel Density?

Definition: EN9 is a medium carbon steel with a typical density of about 7.85 g/cm³ or 7850 kg/m³.

Purpose: This calculator converts between kg/m³ and g/cm³ units for EN9 steel density.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density in g/cm³
• \( \rho_{kg/m³} \) — Density in kg/m³

Explanation: Since 1 g/cm³ equals 1000 kg/m³, we divide the kg/m³ value by 1000 to get the g/cm³ value.

3. Importance of EN9 Steel Density

Details: Knowing the density is crucial for calculating weight, designing components, and material selection in engineering applications.

4. Using the Calculator

Tips: Enter the density in kg/m³ (default 7850 for EN9 steel). The calculator will automatically show the equivalent in g/cm³.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard density of EN9 steel?
A: The standard density is 7.85 g/cm³ or 7850 kg/m³.

Q2: Why are there two different units for density?
A: g/cm³ is commonly used in laboratory settings while kg/m³ is more common in engineering calculations.

Q3: Does EN9 density vary with temperature?
A: Yes, like all materials, density changes slightly with temperature, but this is negligible for most practical applications.

Q4: How do I calculate weight using density?
A: Multiply volume by density (Weight = Volume × Density).

Q5: Is EN9 density different from other steels?
A: Most carbon steels have similar densities (7.8-7.9 g/cm³), with minor variations based on alloying elements.
