What are the units of measure used by early people describe each?
A unit of measurement is a definite magnitude of a physical quantity, defined and adopted by convention and/or by law, that is used as a standard for measurement of the same physical quantity.[1] Any other value of the physical quantity can be expressed as a simple multiple of the unit of measurement.
What is Measurement standard?
I am not sure what is a measurement standard is?
What should a meaningful measurement have?
measurement value (magnitude of the quantity) and a proper unit.
What is an measurement standard?
An exact quantity of people used for a comparison. Their is also scientific notation to standard notation which is changing scientific notation so it would be a standard number.
Who found Pakistan Standard Time?
Sandford Fleming of Canada proposed a world-wide standard of time measurement in 1897, and by 1900 all countries adopted the system, which is used today.

Comparison between an unknown quantity and a standard?
A comparison between an unknown quantity and a standard is known formally as a measurement. In essence, by taking a measurement of a standard against an unknown quantity, you are creating your own system of measurement.
What is meant by unit of physical quantity?
A standard use for a measurement of a physical quantity is called the unit of that physical quantity
What is a fundamental measurement that is defined by a readily reproducible reference standard?
base quantity !!
What is a standard of measurements?
A standard unit of measurement is the unit (size or quantity) that is agreed upon in that nation or trading partnership. In science the standard units of measurement are called SI units. (An international standard). This is the metric system.

What the standard unit used to express a quantity of charges?
The unit of measurement for the quantity of an electrical charge is called an electrometer. The quantity of charge can also be measured in directly by a ballistic galvanmotere.

What is need for measurement of physical quantity?
We come across many things in our daily life that we need to measure. To go to the market in a rickshaw or a taxi we must know its approximate distance from our house. Only then would we have an idea of the expected fare. Similarly, to buy a cloth for our clothes, we should know the approximate length of cloth required. In certain cases we need to know exact values. For example, when we have to buy a pair of shoes, we require the exact size, or when we go to the tailor also requires the exact measurements. Any quantity that we study in physics is known as a physical quantity. Measurement of a physical quantity means comparing it with a known standard quantity. Each accepted standard quantity is a standard of measurement. It is called a unit.The measurement of a particular quantity is the same at all places and at all times. For this purpose, scientists have introduced some standard units for making physical measurements. The standard unit of a physical quantity should have the following characteristics.Fistly it is of a convinient size and secondly Its value dies not change with respect to place or time. A measurement consists of two parts-the magnitude and the units. For example, the length of a cloth is 5 meters. It means that 5 is the magnitude and meter is the standard unit. The study of physics involves measurement of various types. This is why physics is called the science of measurement. To make measurement more scientific, convenient and uniform, in 1791 the French Academy of Science devised the metric system based on the decimal system. In October 1990, the 11th General Conference of Weight and Measures adopted an international system of units known as the SI system of units.
