Convert 100100 Binary to Decimal

100100 binary to decimal conversion provides the detailed information on what is binary (100100)2 in decimal number system, and the step-by-step work for how to convert the binary (base-2) number 100100 to its decimal (base-10) equivalent.

(100100)₂ binary in decimal is equal to:
100100₂ = (1 x 2⁵) + (0 x 2⁴) + (0 x 2³) + (1 x 2²) + (0 x 2¹) + (0 x 2⁰)
= 32 + 0 + 0 + 4 + 0 + 0,
= 36
100100₂ = 36₁₀

Hence,
100100 binary to decimal is 36.

where,
100100₂ is the given binary number,
2 in 100100₂ represents the base-2 or binary number system,
36 is the decimal equivalent of the binary number 100100,
10 in 36₁₀ represents the base-10 or decimal number system.

Steps to convert 100100 binary to decimal
The below step-by-step solution shows how to convert 111101 binary (base 2) to its equivalent decimal (base 10) number.

step 1 Observe the input parameters, values and what to be found.

Input values:

Important Notes: (100100)2 in Decimal
The below are some of the important notes to be remembered while converting the binary number 100100 into a base-10 number.

The sum of increasing power of 2 (from 0 to number of bits minus 1) for each bit of given binary number 100100, that is 2⁰ multiplied with least significant digit (LSD) to 2(no. of bits - 1) multiplied with the most significant digit (MSD) of the given base-2 number provides the equivalent decimal number.

1. The right most digit in the given base-2 number 100100 is a Least Significant Bit (LSB).
2. The left most digit in the given base-2 number 100100 is a Most Significant Bit (MSB).
3. The LSB of 100100 should be multiplied with 2⁰.
4. The MSB of 100100 should be multiplied with 2^{(no. of bits - 1)}.
