1. What is PMMA Density Calculator?

Definition: This calculator computes the density of polymethyl methacrylate (acrylic) based on its mass and volume.

Purpose: It helps engineers, designers, and material scientists determine the density of acrylic materials for various applications.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of the acrylic sample is divided by its volume to obtain the density.

3. Importance of PMMA Density

Details: PMMA typically has a density range of 1180–1190 kg/m³. Knowing the exact density helps in material selection, quality control, and engineering calculations.

4. Using the Calculator

Tips: Enter the mass in kilograms and volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical density range for PMMA?
A: Polymethyl methacrylate (acrylic) typically has a density between 1180–1190 kg/m³.

Q2: How does PMMA density compare to other materials?
A: PMMA is less dense than glass (~2500 kg/m³) but more dense than many other plastics like polyethylene (~950 kg/m³).

Q3: Why measure density for PMMA?
A: Density affects material properties like strength, light transmission, and buoyancy, making it important for specific applications.

Q4: Does temperature affect PMMA density?
A: Yes, like most materials, PMMA expands when heated (lower density) and contracts when cooled (higher density).

Q5: How precise should my measurements be?
A: For accurate results, measure mass to at least 0.01 kg and volume to 0.0001 m³ (equivalent to 100 cm³).
