1. What is Plastic Density Conversion?

Definition: This calculator converts the density of plastic from kilograms per cubic meter (kg/m³) to grams per cubic centimeter (g/cm³).

Purpose: It helps material scientists, engineers, and manufacturers work with density values in different unit systems.

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 equivalent in g/cm³.

3. Importance of Plastic Density

Details: Plastic density affects material selection, product design, manufacturing processes, and quality control. Different plastics have densities ranging from ~0.9 to 1.4 g/cm³.

4. Using the Calculator

Tips: Enter the plastic density in kg/m³ (typically between 900-1400 kg/m³ for most plastics). The calculator will instantly show the equivalent in g/cm³.

5. Frequently Asked Questions (FAQ)

Q1: What's the density range for common plastics?
A: Most plastics range from 0.9-1.4 g/cm³ (900-1400 kg/m³). For example: PP ~0.9, PE ~0.95, PVC ~1.4.

Q2: Why convert between these units?
A: Different industries use different units - kg/m³ is common in engineering, while g/cm³ is often used in material science.

Q3: How precise should my input be?
A: For most applications, 2-3 decimal places are sufficient, as plastic density can vary slightly.

Q4: Does temperature affect plastic density?
A: Yes, density decreases with temperature increase due to thermal expansion.

Q5: Where can I find density values for specific plastics?
A: Material datasheets from manufacturers or engineering handbooks provide precise values.
