MassAccuracyCalculator

How to Use the Calculator

1. Enter the Measured Mass in grams (g). This is the mass that was actually measured.
2. Enter the Theoretical Mass in grams (g). This is the expected or known mass.
3. Click the Calculate button to compute the mass accuracy and absolute error.
4. The results will be displayed as Mass Accuracy (%) and Absolute Error (g).

Understanding the Results

The calculator provides two key measurements:

• Mass Accuracy (%): This indicates how accurate the measured mass is compared to the theoretical mass, expressed as a percentage. A lower percentage means higher accuracy.
• Absolute Error (g): This shows the absolute difference between the measured mass and the theoretical mass, measured in grams.

Example

Suppose you measured a sample to be 10.5 grams, but the theoretical mass should have been 10.0 grams:

- Measured Mass = 10.5 g

- Theoretical Mass = 10.0 g

- Absolute Error = |10.5 - 10.0| = 0.5 g

- Mass Accuracy = (0.5 / 10.0) × 100% = 5.0%

In this example, the measurement has an accuracy of 5.0%, with an absolute error of 0.5 grams.

Applications

This calculator is useful in various fields including:

• Chemistry laboratories for weighing samples
• Manufacturing for quality control
• Pharmaceuticals for measuring active ingredients
• Research for precise measurements
