HEXADECIMAL SYSTEM 

 
  The purpose of the hexadecimal number system is 
simply to reduce the number of units necessary for 
representing any given numerical figure, thereby reducing 
the amount of space in memory necessary to retain it. 
 

  Herein, a decimal (normal) number is converted to a 
correct hexadecimal number which consists of fewer 
characters. 
 
  The hexadecimal number system consists of only 16 
characters which are shown below by the boldface 
characters.

  These characters may be arranged in various sequences to produce an infinite number of representations of decimal 
numbers. For example:  6D4C  =  27,980. 
 

CONVERSION OF DECIMAL WHOLE NUMBER TO HEXADECIMAL NUMBER 

 
1.  Divide the decimal number by 16. 
 

  Example:  57420/16 = 3588.75 

 
2.  Multiply only the fractional part of the product by 16 
to arrive at the first character in the hexadecimal 
equivalent. Remember, all numbers produced I this step 
are shown above. Also note that the product may have no 
fraction (.000) which would result in zero as the 
hexadecimal number. 
 

  Example:  .75  x  16  =  12  =  C 

 
3.  Divide the whole number portion of the product by 16 
thereby producing yet another number. 
 

   Example:  3588/16 = 224.25 

 
4.  Repeat steps 2 and 3 in a cyclical fashion until the 
numerator to be divided in Step 3 is less than 16. At that 
point, the numerator represents the final character in the 
hexadecimal sequence. 
 
 

 
EXAMPLE:  Convert 57,420 into a hexadecimal number: 

 
 

 

1.) 

57,420/16 = 3588.75 

 

 

2.) 

.75  X  16  =  12  =  

C

 

 

3.) 

3,588/16 = 224.25 

 
 

2.) 

.25  X  16  =  

4

 

 
 

 

3.) 

224/16 = 14.00 

 

 

2.) 

.00  X  16  =  

0

 

 

3.) 

14  =  

E

 

 
 

 

  57,420
