Measurements are so often taken for granted we sometimes do not appreciate the grand importance measurements play in our lives. On a baseline level, measurements fall into the categories of weight, area, volume, length and even temperature.

NEED FOR MEASUREMENTS:

While we look at these various categories as stoic forms of mathematical measurements a closer examination of things we do in everyday life reveals their clear importance. Taking proper medicine.If you an illness (whether serious or minor) you need to take your medicine and take it in the proper amount. If you take too little or too much then you are not going to get the proper benefit from it.

Cooking properly. Cooking of all forms is based on proper attention to measurement.

Playing sports. The importance of measurements may not necessarily reveal itself when you play sports but it is there in a big way. If you want to throw a runner out at first or make a 30 yard touchdown pass then you really need to be accurate and comes from a clear sense of depth and distance.

Making estimations. If you have to be at school at 9am what time would you have to leave in the morning if you are at your friend's house. Often we do not have an exact answer so we need to make an estimation which is essentially a guess of measurement.

Clothing is all based on size and proper fitting which are, of course, variants of measurement.

The need for units and standards developed at a point in human history when people needed to know how much of something they were buying, selling, or exchanging. A farmer might want to sell a bushel of wheat, for example, for ten dollars, but he or she could do so only if the unit "bushel" were known to potential buyers. Furthermore, the unit "bushel" had to have the same meaning for everyone who used the term.

NEED FOR STANDARD UNIT:

unit of measurement is some specific quantity that has been chosen as the standard against which other measurements of the same kind are made. For example, the meter is the unit of measurement for length in the metric system. When an object is said to be 4 meters long, that means that the object is four times as long as the unit standard (1 meter).

The term standard refers to the physical object on which the unit of measurement is based. For example, for many years the standard used in measuring length in the metric system was the distance between two scratches on a platinum-iridium bar kept at the Bureau of Standards in Sèvres, France. A standard serves as a norm against which other measuring devices of the same kind are made. The meter stick in a school classroom or home is thought to be exactly one meter long because it was made from a permanent model kept at the manufacturing plant that was originally copied from the standard meter in France.

All measurements consist of two parts: a scalar (numerical) quantity and the unit designation. In the measurement 8.5 meters, the scalar quantity is 8.5 and the unit designation is meters.

Measurement of mass

Measurement of mass is most commonly done by a Balance. The unknown mass of a body is compared with a known value of mass. We obtain the value of an unknown mass in terms of a known value of mass. A balance works in space and in places of no gravity as well since changes in gravity affect both the masses on the balance equally.
