How to Convert Binary to Decimal Numbers?
If you want to convert binary to decimal then you want to know the calculation. Here we have one example for you with perfect calculation.
Example:
Binary Number = 100101010Here we have 100101010 binary. We want to convert this number to a decimal number. Let’s see how to calculate. Here we have two types of method:
Method 1:
For binary number with n digits:
dn-1 ... d3 d2 d1 d0
The decimal number is equal to the sum of binary digits (dn) times their power of 2 (2n):
decimal = d0×20 + d1×21 + d2×22 + ...
= 100101010=(0 * 20) + (1 * 21) + (0 * 22) + (1 * 23) + (0 * 24) + (1 * 25) + (0 * 26)+ (0 * 27) + (0 * 28) + (1 * 29)
= (0 * 2) + (1 * 2) + (0 * 4) + (1 * 8) + (0 * 16) + (1 * 32) + (0 * 64) + (0 * 128) + (1 * 256)
= 0+2+0+8+0+32+0+0+256
= 298
Binary Number 100101010 = 298 Decimal NumberMethod 2:
= 100101010= First, we split all the Numbers
1 0 0 1 0 1 0 1 0
Now we start with multiply with (0*2) + 1 (Single numbers of the split)
(0*2) + 1 = 1
(1*2) + 0 = 2
(2*2) + 0 = 4
(4*2) + 1 = 9
(9*2) + 0 = 18
(18*2) + 1 = 37
(37*2) + 0 = 74
(74*2) + 1 = 149
(149*2) + 0 = 298
Here is your Answer 298
Binary Number 100101010 = 298 Decimal NumberThese are two types of methods where you can convert binary to decimal.
