What is conversion of numbers?
As we know, the number system is a form of expressing the numbers. In number system conversion, we will study to convert a number of one base, to a number of another base. There are a variety of number systems such as binary numbers, decimal numbers, hexadecimal numbers, octal numbers, which can be exercised.
How do you convert any number?
Step 1 − Divide the decimal number to be converted by the value of the new base. Step 2 − Get the remainder from Step 1 as the rightmost digit (least significant digit) of new base number. Step 3 − Divide the quotient of the previous divide by the new base.

Why is number conversion necessary?
Rather, those words and letters are translated into numbers. This means that computers understand only numbers. By studying other number systems such as binary (base 2), quaternary (base 4), octal (base 8), hexadecimal (base 16) and so forth, we will gain a better understanding of how number systems work in general.
What are the steps in conversion binary numbers to decimal?
Binary to Decimal Conversion Using Doubling Method
- Step 1: Write the binary number and start from the left-most digit. Double the previous number and add the current digit.
- Step 2: Continue the same process for the next digit also.
- Step 3: Continue the same step in sequence for all the digits.
