Frequently Asked Questions

Binary to decimal conversion is the process of converting a number written in base-2 (binary) system, which uses only 0s and 1s, into a base-10 (decimal) number that humans commonly use. Each binary digit (bit) represents a power of 2, and the decimal value is the sum of all active bits.

To manually convert binary to decimal, multiply each binary digit by 2 raised to its position power (starting from 0 on the right), then add all results. For example, binary 1101 = (1×8) + (1×4) + (0×2) + (1×1) = 13 in decimal.

Binary 11111111 equals decimal 255. This is the maximum value of an 8-bit unsigned integer, commonly used in networking (255.255.255.255) and color values (RGB max per channel).

Computers use binary because electronic circuits have two stable states: on (1) and off (0). Binary simplifies circuit design, increases reliability, and enables logical operations. Every piece of data — text, images, videos — is ultimately stored as binary in computer memory.
