How bits are mapped to decimal values
Bits can be mapped into decimal values. Each bit can be either on (1) or off (0). Eight bits create 256
unique combinations of 1s and 0s. Each of the eight bits can be assigned a number corresponding to
its position:
b b b b b b b b
7 6 5 4 3 2 1 0
Also, each bit can be assigned a value corresponding to its number (e.g., the value equals 2 to the
power of the bit):

Converting Bits to Decimal Values
Starting with a string of eight bits, assign each "1" bit a value based on its position. Add the values to
come up with the final decimal value.
Here’s an example of how bits are converted to decimal values:
