Grade 4 Measurement - 4.MD.A.1
What is the Metric System? Ever wondered why is there so much hype about the metrics system? Well, the answer lies in understanding the metrics system. The metrics system is the system of measuring. It is a decimal system that was originally adopted in France first, a system of weights and measures. The system is now widespread universally and used as mandatory in a large number of countries. The basic units that are a part of the metrics system are; 1. Meter (inches) used for measuring length. 2. Grams for measuring mass or weight. 3. Liter used for mostly liquid volume and measuring the capacity. 4. Square yards, square meters, cubic feet. The metric system was modified in the 20th century to have a system of measurements that goes beyond simple length, weight, and volume. This system proved to be very helpful in science and technology. Apart from the above-mentioned units, the metric system has the following units too: m - the meter for length. kg- the kilogram for the mass. sec - the second for time. These worksheets and lessons introduce students to measuring items and converting between metric units.

What Countries Use the Metric System and Which Do Not?
After writing this title, I realized I could have greatly shortened it. This is because only three countries of what the United Nations recognizes as a planet of one-hundred and ninety-five countries do not follow the metric system. The non-followers include Burma, Liberia, and the United States. All one-hundred and ninety-two other countries use the metric system as their standard of measurement. While we say that these three outliers are renegades, they do use slight elements of the metric values. The bigger question should be what is the United States thinking? Get with the program big guy! The United States have official adopted the International System of Units to make things even more complicated. This means that in some walks of life you will see metric units pop their head up. Some industries that involve trade are solely focused on the metric units even American companies; they simply do not have a choice if they want to trade with the rest of the world. This means that many students grow up learning a different form of measures than they will use in their everyday life. There are basically two things holding up the United States from fully adopting the metric system. The first being the costs involved in converting all the gauges and measurement tools we use. Imagine you have a tape measure that measure length in feet and inches. The minute the conversion happens that is useless from here in. Think of all of the other non-metric gauges and tools we all use; we would need to replace all of them. Replacements cost money. The other reason holding the conversion by American is because it is a culture that doesn’t like discomfort. As the baby boomers hand the keys over to younger generations, we slowly begin to understand that we are a softer culture.
