Accuracy
STD on the other hand measures precision.
You can measure some aspects of quantum uncertainty.
accuracy is when you KNOW something and uncertancy is when your not sure
Several factors can contribute to the uncertainty of a tape measure's measurements, including the tape measure's material and thickness, the accuracy of its markings, any wear and tear on the tape, and how tightly the tape is pulled when measuring. These factors can all affect the precision and reliability of the measurements taken with a tape measure.
Accuracy is the distance away in percent of a result (or a measure) from the target. This mathematical definition is from the book "A Mathematical Foundation For Politics And Law"
It is the accuracy in the estimate of the constant or the effect of rounding.
The uncertainty of an oscilloscope can affect the accuracy of electronic measurements by introducing errors or variations in the displayed waveform, leading to inaccuracies in voltage, frequency, and timing measurements.
"3 meters measure water flow90 percent thro meter 1 accuracy of 3 percent8 percent thro meter 2 accuracy 10 percent and2 percent thro meter 3 accuracy 15 percent what is accuracy combined?"if in metre 1 (0.9 X 0.03) = .027and in metre 2 (0.08 X 0.10) = .008and in metre 3 (0.02 X 0.15) = .003then total combined accuracy is 0.027+ 0.008 + 0.003 = 0.038 = 3.8 percent
To calculate the percent uncertainty, divide the absolute uncertainty by the measured value and multiply by 100. Here, the absolute uncertainty is 0.25 m, and the measured value is 3.26 m. The calculation is (0.25 m / 3.26 m) × 100, which equals approximately 7.67%. Thus, the percent uncertainty in the measurement is about 7.67%.

The uncertainty of gravity can affect the accuracy of scientific measurements by causing variations in weight and mass measurements. This can lead to discrepancies in experimental results and hinder the precision of scientific data analysis.
The uncertainty in radius is approx 5.95%.
