Thread Diameter
0.25 cm
Method: Wrap the thread tightly around a pencil or rod for 'n' turns. Measure the length 'L' of the coiled turns. The diameter of the thread is calculated as D = L/n.
Least Count
0.005 mm
Calculation: Least count = Pitch / Number of divisions. Increasing divisions theoretically improves accuracy, but practical limitations like mechanical play and manufacturing precision eventually limit real-world accuracy.
Mean Diameter
5.02 mm
Standard Deviation
0.12 mm
Explanation: More measurements provide better statistical reliability. The mean becomes more representative of the true value, and we can better estimate measurement uncertainty through the standard deviation.
