NO. But, if you can't reproduce it, it ain't science.

That depends whether the thing you're measuring is closer to 178 inches or 12 feet.However, if you round to the nearest measurement, a measurement of 178 inches can be within 2.54 centimetres of accuracy, while a measurement of 12 feet can be within 15.24 centimetres of accuracy - therefore making inches a much more accurate measurement.
Accuracy, precision, repeatability and so on are terms that have been closely defined for measurement purpose. By folk such as ASTM. and ISO.The true value is the value towards which a large number of different measurements (by different measurement teams, using different measuring systems ... ..) tends.The accuracy of a particular method or measurement is how closely that answer comes to the True Value.The precision of a measurement represents the confidence you have in the measurement. (Generally by making several measurements.)The resolution of a measurement is merely the number of figures in your answer. A number with many places would have greater resolution, but many of those numbers might be meaningless.So, a single measurement of the height of a mountain for example, might be correct, (true value) but you don't necessarily have reason to be confident of the answer.

Measurement is important for tracking progress, evaluating results, making informed decisions, and identifying areas for improvement. It provides quantifiable data that can be used to monitor performance, set goals, and ensure accountability. Additionally, measurement enables organizations to demonstrate their impact and effectiveness to stakeholders.
Accuracy has more to do with the measurement lines on the ruler than the material. In terms of making measurements , however, a steel ruler has several advantages to a plastic ruler of the same accuracy. For starters, steel rulers are often thinner than plastic rulers, positioning the measurement lines closer to the paper. As well as this, many steel rulers feature a backing made of a gripping material such as cork, which keeps the ruler firmly planted while drawing lines and making measurements. Lastly, the measurement lines on steel rulers are frequently embedded into the metal, whereas plastic rulers tend to have the lines painted on. After a while, these marks can be worn away, reducing the accuracy and readability of a plastic ruler.
