2.2. Number System Conversion
We can convert a number from one number system to another and vice versa.
In the following, we discuss conversions among different number systems.
2.2.1 Decimal to Binary and Binary to Decimal
• Decimal to Binary
To convert a decimal number to binary, we divide the number by 2 and
take quotient and remainder. We continue dividing the quotient by 2 until
we get quotient 0. We write out all the remainders
obtain the value in binary.
Example:
Convert 156
10 (156 in decimal) to binary
Table 2-1 shows the method to solve this
problem. Remainders are taken from bottom to
top to present the binary number. So,
156
10 = 100111002.
Activity 2.1
How many marks did you obtain in the final examination of 8th class? Convert that
figure to binary and discuss the result with your class fellows.
• Binary to Decimal
The conversion of a number from binary number system to decimal
number system is explained below with the help of an example.
Example: Convert (1000001)2 to decimal
= 1 x 26 + 0 x 25 + 0 x 24 + 0 x 23 + 0 x 22 + 0 x 21 + 1 x 2°
= 64 + 0 + 0 + 0 + 0 + 0 + 1
= (65)10
The above conversion is done by the following steps.
Step 1. Write down the binary number which is (1000001)2 in this example.
Step 2. List the powers of two from right to left starting with 0. In this
example, the power of 2 starts from 0 and ends at 6.
Step 3. Multiply 2's corresponding powers to each binary value. In the
above example there are 7 binary values.
Step 4. Compute each value.
Step 5. Add all the values.
Step 6. Write the answer along with its base subscript.

Activity 2.2
Exchange your marks in binary form with your friends and convert them in decimal
to know about their expectations in the board examination of 9th class. Double
check with your class fellows that how much your calculations are accurate.
