We can achieve this by controlling the number of digits, or significant figures, used to report the measurement. . On what measurements do we apply the different and appropriate units? In measuring dimensions, it is proper to use units such as meter, centimeter, millimeters, inches, Feet, and so on. In measuring weight, it is proper to use units such as kilograms and grams. In measuring temperature, units such as Celsius, Fahrenheit, and Kelvin are appropriate. And in measuring time, seconds, minutes, our daily lives? Accuracy on measurements plays a vital role in our daily lives.

Architecture and construction depend heavily on the accuracy of measurement. Chemists and harmonicas also place a great deal of importance on measurements in the medicines or anything that they make or invent. Without accurate measurement, a great deal of humanity's physical accomplishments would not be possible. 4.

What is the difference between accuracy and precision? In definition, Accuracy is the degree of conformity of a measured or calculated quantity to its actual (true) value, while precision is the degree to which further measurements or calculations show the same or similar results.Another difference between the two can be that accuracy can be determined by one measurement while any measurements are needed to determine precision. For example, by Just one arrow fired, one knows if it is accurate or no but a number of arrows have to be fired to know if the result is precise or no. Veil. CONCLUSION After the experiments and researches that I have done, I therefore conclude that measurements are a big and a very important part of our daily lives. Precision and accuracy in measurements also affect our lives because of one mistake, a lot things unexpected might happen.

And as we all know, physics is a subject that includes amputation. Without measurement we won't know distances, height, weight, length, and etc. 'X. PERSONAL REACTION This experiment was fun and exciting for me because of the new tools I used for measuring different objects. This was my first time to measure diameter of a marble and a tube using the fernier caliper, and the thickness of a paper using the micrometer caliper and I was pretty amazed because for the past years we always try measuring the using a ruler but now we found out that there are other tools really intended for measuring those objects.
