The document outlines a project report for a C language program designed to convert physical quantities such as temperature, time, and length. It details the programming techniques used, including functions, conditional statements, and formulas for conversions between different units. The report also includes acknowledgments and a flow chart of the converter program.

Acknowledgements
The whole praise is to Almighty Allah, creator of this universe, who made us
the super creature with great knowledge. We, Zuhaib Ali, Muhammad Shoaib,
as a group of student of Newports Institute of Communication and Economics,
pays great thanks to our teacher Miss Farah Nawaz, who has given us the
golden opportunity to do this wonderful project, that helped us in doing a lot
of research and we came to know about so many new things and ideas.
In last but not the least, we would like to thank our parents and friends who
prayed for our success and encouraged us during this research period and
supporting us throughout our lives.
Introduction
During the fall 2013 semester, our teacher told us to create a program in Turbo
C Compiler using C Language. We decide to create a Converter that can
convert Temperature, Time and Length. Because in creating such a program we
can learn many new techniques about how to make program.
After we complete the program, now we really know many things that we
don’t know previous.
Conversations
In our program we have give three physical quantities to be converter from its
one unit to another. These physical quantities are listed below.

Temperature

Time

Length

Programming
In this section we will describe the program in programming aspect. Like what
is the technique working behind the program? And how the program actually
works?
Header file
In this program we have included only one header file that is Stdio.h.
Stdio.h file is the name of the standard library definition file for all Standard
Input, Output.
Switch case
We used switch case statement to make decisions or choices based on the
value of a conditional expression and specified cases.

If- else statement
Now we have used if-else statement the relational operators for making
comparisons, The if-else statement is used to express decisions,
expression
true Statement1
Next statement
If expression evaluates to false, Statement2 that follows the else keyword is
executed, and the program continues with Next_statement
Custom function
We have created 11 custom functions in our program.

Temperature
o Celsius to all
o Fahrenheit to all
o Kelvin to all

Time
o Day to all
o Hour to all
o Minute to all
o Second to all

Length
o Centimeter to all
o Foot to all
o Inch to all
o Meter to all

Temperature
Temperature is most common physical quantity; it is use to measure how of
hot or cold an object is. It may be measure in any of various units such as
Celsius, Fahrenheit, Kelvin, Rankine, Delisle, Newton, etc. We have given three
frequent used units in our program to converter from one to both others.
These units are listed below

Celsius

Fahrenheit

Kelvin
Formulas
The formulas used for temperature conversations in this program are as given
in below table.
From
Temperature
Fahrenheit
Kelvin
Celsius
=
(Fahrenheit-32)/1.8
Kelvin-273.15
Fahrenheit
Celsius*1.8
=
(Kelvin*1.8)-459.67
Kelvin
To
Celsius
Celsius+273.15
(Fahrenheit+459.67)/1.8

Result
After selecting the input unit program the program ask to enter temperature in
selected unit and calculate the result in other units and print it.
Example
Time
Time is another common physical quantity; the indefinite continued progress
of existence and events in the past, present, and future regarded as a
whole.Time is measured in hours and minute’sseconds, days, weeks, years,
decay, etc. We have given four units in our program to converter from one to
other three units. These units are listed below

Days

Hours

Minutes

Seconds

Formulas
The formulas used for time conversations in this program are as given in below
table.
From
Time
Hours
Minutes
Seconds
Days
=
Hours/24
Minutes/60/24
Seconds/60/60/24
Hours
Days*24
=
Minutes/60
Seconds/60/60
Minutes
Days*24*60
Hours*60
=
Seconds/60
Seconds
Days*24*60*60
Hours*60*60
Minutes*60
=
To
Days
Result
After selecting the input unit program the program ask to enter time in
selected unit and calculate the result in other units and print it.
Example
Length
Length is also another common physical quantity; that is used to measure
distance between two points.It is measured in foot, inch, kilometer, mile,
meter, millimeter, yard, etc. We have given four units in our program to
converter from one to both others. These units are listed below

Centimeter


Foot

Inch

Meter
Formulas
The formulas used for Length conversations in this program are as given in
below table.
From
Length
Foot
Inch
Meter
Centimeter
=
Foot*30.48
Inch/0.3937
Meter*100
Foot
Centimeter*0.033
=
Inch/12
Meter/0.3048
Inch
Centimeter*0.398
Foot*12
=
Meter/0.0254
Meter
Centimeter*100
Foot*0.3048
Inch/39.37
=
To
Centimeter
Result
After selecting the input unit program the program ask to enter Length in
selected unit and calculate the result in other units and print it.
