Octal to decimal binary hexadecimal converter provided on this web page is an effective tool which can be used to convert octal in to decimal, binary and hexadecimal in a fracture of second.
Decimal :
Decimal is nothing but the number we use in our day to day life. Whatever number we write in our day to day life, we use the ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Since we use one or some of these ten digits in decimal, we say that decimal is having base 10.
Binary:
In digital electronics, we write the numbers using only the two digits "0" and "1". Whatever number we we have in regular, it will be written in digital electronics only by using the two digits "0" and "1".
Since we use only the two digits "0" and "1" in binary, we say that binary is having base 2.
Octal:
Octal is nothing but the number we write using the eight digits 0, 1, 2, 3, 4, 5, 6, 7.
Since we use one or some of these eight digits in octal, we say that octal is having base 8.
Hexadecimal:
Hexadecimal is nothing but the number we write using the sixteen digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F.
Here A =10, B = 11, C = 12, D = 13, E= 14, F = 16
Whatever number we have in regular, it will be written in hexadecimal using these 16 digits.
Since we use one or some of these 16 digits in hexadecimal, we say that hexadecimal is having base 16.
The above explanation of decimal, binary, octal and hexadecimal is more clearly shown in the below picture.
When students do lengthy problems in math which is the part of the syllabus in college level computer courses, they may have to convert octal into decimal, binary and hexadecimal as a part of the math problem.
