  1. History of Measurement

  2. The Egyptians were one of the first civilizations to record measurements. They used sundials to tell time and levels. The accuracy of the measurements is demonstrated in their skill of building pyramids and other great monuments that have lasted thousands of years.

  3. During the time of the Roman Empire, a foot was the length of a grown man’s foot. This obviously led to some variation in length as everyone’s foot is different. Nevertheless, this was a monumental step towards the standardization of measuring.

  4. The metric system was created to measure and weigh objects with better accuracy and precision. Because the metric system is based on a power of ten, units in the metric system are extremely simple to convert. The SI, used by the British and US, simply was not practical for many applications.

  5. “The Treaty of the Meter” was a treaty in 1875 that oversees the accuracy and keeping of metric standards. As a result of the meeting in 1875 the “International Bureau of Weights and Measures” was established.

  6. The 18th century brought many new ideas especially to France. They decided to standardize the meter. In 1791 the length of a meter was defined as the length of 1/10,000,000 of the distance between the equator and the North Pole.

  7. In 1983, the length of a meter was redefined as the distance light travels in a vacuum in approximately 1/300,000,000.

  8. The Metric Act of 1866 becomes enacted into law and legalizes the standardization of weight and measurement. Although the metric system had already been created, this legally protected the standardization.

  9. Before measurement was standardized, the human body was used to aid in measurement.

  10. Great Kersten Blunder: • The Vigor Space Probe had a programming error in it’s converting program. This error caused it to miss Venus and the probe was sent hurling into space. Over two billion dollars of technology was lost because of one calculation error.
