Capacity: The amount that an object can hold is defined as its capacity. Weight: weight is the measure of the heaviness of the object. There are seven base units measurements namely meter m , kilogram kg , second s , ampere a , Kelvin K , mole mol , and candela cd.
Image to be added soon. The most common among these are kilograms, seconds, and meters. Standard units are used in measurement for more accuracy. The measurement should be the same for all. As there needs to be uniformity in the measurement, we must have a common set of units in measurement. These are called standard units. The standard unit is different for different quantities. The standard unit of measurement is a value that is fixed and cannot be changed. It is needed to have uniformity in measurement.
The measurement is measured as feet, inches, and pounds in the United States and meters, centimetres, and kilograms in the metric system. There are two types of measurements, namely Standard and non-Standard. Standard measurement units are those which are used within the measurement system such as ounces, inches, and pounds. It helps everyone to understand measurements in a set of unit systems. For example: they would need to know that 1. They would continue to do practical measuring activities and problem-solving.
They may come across problems where they have to convert units of measurement in order to work out the answer. For example: I am 1. My baby sister is 86cm tall. How much taller am I than my sister? Children would continue this kind of problem-solving in Year 5 and would most likely be required to solve measures problems involving all four operations addition, subtraction, multiplication and division.
In Year 6, they would again continue this kind of problem-solving, but would be required to convert between units using decimals to three places, for example: change 6. More like this. Using non-standard measures: height. What is capacity? Using non-standard measures: length.
Using non-standard measures: weight. Make hand and foot measuring sticks. Now, this unit has been standardized into the Imperial System as 0.
So, the difference between a size 8 shoe and a size 9 is one barleycorn. The Imperial System was derived greatly from the measurements that were used by the Romans. Important concepts taken from the ancient system include uncia , the base unit that became the modern inch, pes , which comprised 12 unciae and became the modern foot, and mille , which was the basis for the modern mile. The measurements for these were determined by using the average foot length of the Roman Centurion. These units had to be altered slightly for incorporation into the Imperial System, but the base of 12 units still remains today.
Royalty had a great impact on the adaptation of these Imperial measurements. For example, it is thought that King Henry I decreed that a yard should be the distance from the tip of his nose to the end of his outstretched thumb, which was approximately three feet.
The Tudor rulers established that a furlong is yards, later encouraging Queen Elizabeth I to declare in the 16 th Century that one mile should be feet, not the traditional Roman feet. This made one mile exactly eight furlongs, creating a convenient relationship between the two. Several royal edicts in the 18 th Century gave England a higher degree of standardization than other nations, which also implanted the Imperial System into its many colonies and territories.
The Metric System was first adopted following the French Revolution. There was a need for measurement standardization, since at the time there were different units that could be used to measure land in France. The Metric System has specific units that are based off of 10, which makes it easy to understand and very convenient for conversions. However, according to History , the Metric System in France did not originally last long in retail, being abolished by Napoleon in , but it was later reinstated in By then, many countries had begun to adopt it.
After near-universal adoption of the Metric System, there were still some nations that initially not abide to the process of metrication.
Other than countries such as the United States, which used the US Customary System, a system that was developed with units similar to that of the Imperial System, some places continued to use their traditional units of measurement that had been around for centuries. For example, prior to its adoption of the Metric System in , China primarily used a unique system of measurement that contained base units of
