What is Binary to Decimal Conversion?

Binary is a number system that uses only two digits, 0 and 1. It is the foundation of computer systems and digital logic. Decimal, on the other hand, is the number system we use in everyday life, based on 10 digits (0-9).

Converting decimal binary numbers is important because computers work in binary, while humans usually work in decimal.
