Frequently Asked Questions

QWhat is base conversion?

Base conversion is the process of converting a number from one base representation to another. Common bases include binary (Base 2), octal (Base 8), decimal (Base 10), and hexadecimal (Base 16).

QHow to use this base converter tool?

Select the input base, enter the value, and the tool will automatically convert it to other bases in real-time. Supports conversion between binary, octal, decimal, hexadecimal, and more.

QWhat is BCD code?

BCD (Binary-Coded Decimal) is a binary encoding of decimal numbers where each decimal digit is represented by 4 binary bits. For example: decimal 25 is represented as 0010 0101 in BCD.

QWhat is Gray code?

Gray code is a binary encoding system where adjacent numbers differ by only one bit. It's commonly used in encoders and communication systems to reduce errors.

QWhat is two's complement?

Two's complement is the standard method for representing signed integers in computers. Positive numbers have the same representation as their magnitude, while negative numbers are represented by inverting all bits of the absolute value and adding 1.
