By the end of eighteenth century, throughout the world, people have
frequently used a range of different units and systems of measurement.
For instance, people measured length in inches, feet, miles, cubits,
spans, hands, palms, furlongs, rods, leagues chains, and so on.
The inadequate common standards resulted in many confusions and
huge ineffectiveness in trade among nations. Hence, at the end of
this century, the French government wanted to get rid of this issue
by formulating a system of measurement to use it throughout the world.
Different Aspects of Measurement Used:
The Decimal System
It is the commonly used system of measurement and calculations. It
is derived from the Latin word Decimus. The key rule of the decimal
system is that 10 is a new unit from where the decimal counting begins
again. Next, people calculate the multiples of 10 by the same systems
as 1 to 9.
The Metric System
It is a French phrase related to the French term for measure. It
is a decimal system of measuring made by French Law during the era
of French Revolution and used by the people throughout the world widely.
This system uses meter as its basic unit, liter as its basic capacity
unit, and grams as its basic mass or weight unit.
Common Computer Measurements:
Hertz & Megahertz
Hertz is the frequency unit. The insignia for hertz is Hz. One hertz
denotes one cycle in a second. The shaft of light behind your PC will
get across the entire monitor at least 60 times each second, if the
monitor is not to flicker. This is described as a 60 Hz of refresh
rate. The velocity of your computer processor is measured in terms
of megahertz. One megahertz denotes one million cycles in a second.
The insignia for megahertz is MHz.
Megabyte and Gigabyte
Your PC's file size and storage capacities are measured in terms
of bytes. A byte has adequate space to save or store one character
or letter. If you follow-up the naming convention for the system of
metric, a kilobyte might represent one thousand byte, similar to kilometer
which represents one thousand meters, whereas a kilogram is one thousand
Generally, this is a fact, because the basic function of a computer
is in twos (the binary system) and not in tens (the metric system).
However, several people contemplated that, it would great to have
byte measurements in handy numbers via the binary system.
Hence, people refer byte measurements as:
- 1 kilobyte is 1,024 bytes or simply one thousand bytes.
- 1 megabyte is 1,048,576 bytes or about one million bytes.
- 1 gigabyte is 1.073,741,824 bytes or one thousand million bytes.
Cold or hot is usually measured in concern with two points: The point
on which a matter or substance transforms from solid to liquid state,
or liquid to solid state is freezing point. The point at which a substance
transforms from liquid to a vapor, or vapor to liquid state is the
boiling point. Every substance transforms at different temperatures,
so one usual base substance used is water.
Centigrade or Celsius scale, as it is widely known is actually a
decimal scale. It scales or measures the freezing point of water at
0 degree and the boiling point at 100 degrees.
Natural Units of Measurement:
Natural units are natural, since the source of their explanation
arrives only from properties of nature and not from any artificial
source. Different varieties of system of natural units are possible
Below is a list of some of the natural units of measurement:
1. Planck units
2. Stoney units
3. Schrodinger units
4. Geometric unit systems
5. Electronic units
6. Quantum electrodynamical units
7. Atomic units
