Unsigned binary number (base two) 101 1111 converted to decimal system (base ten) positive integer

How to convert an unsigned binary (base 2):
101 1111(2)
to a positive integer (no sign) in decimal system (in base 10)

1. Map the unsigned binary number's digits versus the corresponding powers of 2 that their place value represent:

    • 26

      1
    • 25

      0
    • 24

      1
    • 23

      1
    • 22

      1
    • 21

      1
    • 20

      1

2. Multiply each bit by its corresponding power of 2 and add all the terms up:

101 1111(2) =


(1 × 26 + 0 × 25 + 1 × 24 + 1 × 23 + 1 × 22 + 1 × 21 + 1 × 20)(10) =


(64 + 0 + 16 + 8 + 4 + 2 + 1)(10) =


(64 + 16 + 8 + 4 + 2 + 1)(10) =


95(10)

Conclusion:

Number 101 1111(2) converted from unsigned binary (base 2) to positive integer (no sign) in decimal system (in base 10):


101 1111(2) = 95(10)

Spaces used to group numbers digits: for binary, by 4.

All the converted unsigned binary numbers, from base two to base ten

How to convert unsigned binary numbers from binary system to decimal? Simply convert from base two to base ten.

To understand how to convert a number from base two to base ten, the easiest way is to do it through an example - convert the number from base two, 101 0011(2), to base ten:

  • Write bellow the binary number in base two, and above each bit that makes up the binary number write the corresponding power of 2 (numeral base) that its place value represents, starting with zero, from the right of the number (rightmost bit), walking to the left of the number, increasing each corresponding power of 2 by exactly one unit each time we move to the left:
  • powers of 2: 6 5 4 3 2 1 0
    digits: 1 0 1 0 0 1 1
  • Build the representation of the positive number in base 10, by taking each digit of the binary number, multiplying it by the corresponding power of 2 and then adding all the terms up:

    101 0011(2) =


    (1 × 26 + 0 × 25 + 1 × 24 + 0 × 23 + 0 × 22 + 1 × 21 + 1 × 20)(10) =


    (64 + 0 + 16 + 0 + 0 + 2 + 1)(10) =


    (64 + 16 + 2 + 1)(10) =


    83(10)

  • Binary unsigned number (base 2), 101 0011(2) = 83(10), unsigned positive integer in base 10
