Meter is also called the SI unit of length or base unit of length.It is important to convert different units of length into one before solving the questions.The measurement of length chart is given below showing the conversion of metric units, imperial units, metric to imperial units, and imperial to metric system units of length. For example, if we know that 1 yard = 36 inches, we can easily convert 3 yards to inches by multiplying 3 by 36. The measurement of length chart helps us to convert a unit to another unit easily. Its value in some other units are given below: As shown in the above chart, the meter is the base unit of length. The SI unit of measurement of length is meter (m). Some of the non-standard units of length are handspan, foot span, finger width, pace, cubit, a thread or a rope, etc. This is because the handspan of a child is usually smaller than an adult. For example, if a child and his father measure the length of a rectangular wall using their handspan, it is most likely that they will get different values. They vary from person to person and from object to object. Non-standard Units of Measuring Length: Such units do not have a fixed measurement in numbers. Look at the chart of units of measuring length under the metric system given below. The relationship of every other unit with the base unit (meters) is given below: Among these units, meters is the base unit. There is a special relationship shared by these units. These units include kilometer, hectometer, decameter, meter, decimeter, centimeter, and millimeter. We also have metric units to measure length. Let us see the unit conversion table for the imperial measurement system of length. Some commonly used units in the imperial measurement systems are. The Weights and Measures Act of 1824 and the Act of 1878 established the British Imperial System on the basis of precise definitions of selected existing units. The imperial system of units is the system of units first defined by the British, to measure different quantities. Standard units can again be divided into two types: Imperial units and metric system units. Some examples of standard units of length are meters, centimeters, inches, feet, yards, etc. If two or more people will measure the length of the same object using any standard unit, say inches, they will get the same result. Standard Units of Measuring Length: Such units are pre-defined and do not change person to person or object to object. Look at the chart below showing units of length. The units of measuring length can be classified into two types: Standard units of measuring length and non-standard units of measuring length. Length can be measured in different units like centimeters, inches, meters, or by using a handspan, foot span, etc. Here, the length of the pencil is 8 centimeters which is one of the units of measuring length. Look at the image given below showing the act of measurement of the length of a pencil using a ruler. Many times, we do not use a particular scale or tool to measure length but only guess it based on our understanding of units of length and observation. Thus, measuring length is an important skill to be used in our everyday life. But if you want to tell the length of that vase to somebody who is not there, how will you do it? We can do that if we know its value in a certain unit, say 4 feet. Imagine going to a store with your friend and observing a beautiful vase to place in your drawing room. The skill of measuring the lengths of objects and understanding the units of length is very crucial as it helps us to interact with our environment in a more organized manner. Measurement of length is defined as the act of measuring the length of objects in some specified units which can be standard or non-standard.
