Density % Difference
What is Percentage Difference in Density?
The percentage difference in density is a way to compare how different two density values are relative to their average. It’s commonly used in material science, quality control, and fluid mechanics to assess variations between theoretical and experimental values or between two materials.How to Calculate Percentage Difference in Density
You can calculate the percentage difference using the following formula:- Percentage Difference (%) = |Density 1 – Density 2| ÷ [(Density 1 + Density 2) / 2] × 100
- The result tells you how much the two values differ in percentage terms, regardless of which one is greater.
| Sample Material | Density 1 (kg/m³) | Density 2 (kg/m³) | % Difference |
|---|---|---|---|
| Water at 20°C vs 25°C | 998 | 997 | 0.10% |
| Oil Batch A vs Batch B | 890 | 875 | 1.70% |
| Plastic Sample Test | 1200 | 1180 | 1.69% |
| Experimental Metal vs Spec | 7850 | 8000 | 1.89% |
