Conversion Formula
The conversion from binary to decimal involves summing the products of each binary digit with 2 raised to the position's power, starting from zero on the right. This works because binary is a base-2 system where each position is a power of 2.
For example, 1001011 can be broken down as:
1×2⁶ + 0×2⁵ + 0×2⁴ + 1×2³ + 0×2² + 1×2¹ + 1×2⁰ = 64 + 0 + 0 + 8 + 0 + 2 + 1 = 75
Conversion Example
- Number: 10110
- Identify each digit from right to left: 0, 1, 1, 0, 1
- Calculate each as digit×2^position: 0×2⁰=0, 1×2¹=2, 1×2²=4, 0×2³=0, 1×2⁴=16
- Sum all: 0+2+4+0+16=22
- Number: 1101
- Digits: 1, 0, 1, 1
- Calculations: 1×2³=8, 0×2²=0, 1×2¹=2, 1×2⁰=1
- Total: 8+0+2+1=11

Conversion Definitions
Binary
Binary is a number system that uses only two digits, 0 and 1, to represent data. It is the foundation of digital electronics and computing, where each digit, called a bit, signifies an on or off state, enabling complex information to be stored and processed with simple binary codes.
Decimal
Decimal is a base-10 number system that uses ten digits from 0 to 9 to represent numbers. It is the standard counting system for humans, where each position in a number indicates a power of 10. It is used for everyday counting, calculations, and numerical representation.
Conversion FAQs
How do I convert binary 1001011 to decimal without a calculator?
To convert manually, write down each binary digit with its corresponding power of 2, starting from right to left. Multiply each digit by 2 raised to its position, then sum all the results. For 1001011, sum 1×2⁶ + 0×2⁵ + 0×2⁴ + 1×2³ + 0×2² + 1×2¹ + 1×2⁰, which totals 75.
Is binary 1001011 a prime number in decimal?
No, the decimal equivalent 75 is not a prime number because it can be divided by numbers other than 1 and itself, specifically 3 and 25. Prime numbers only have two positive divisors, 1 and the number itself.
