Accuracy vs Precision in Weighing
Accuracy and precision are different concepts.
Accuracy
How close the measured value is to the true weight.
Precision
How consistently the same value is repeated.
Example
Actual Weight
100.000 g
Reading 1
100.001 g
Reading 2
100.001 g
Reading 3
100.001 g
This indicates high precision and high accuracy.
Importance
1.) Calibration
2.) Laboratory work
3.) Quality control
4.) Manufacturing
