Question 1

How do I convert binary to decimal?

Accepted Answer

Enter your binary number (e.g. 1010) in the Binary field. The decimal, octal, and hex values update automatically. 1010 in binary equals 10 in decimal.

Question 2

What is hexadecimal used for?

Accepted Answer

Hexadecimal (base 16) is widely used in computing for memory addresses, color codes (e.g. #FF5733), and byte representations because it is compact and maps cleanly to binary (each hex digit = 4 bits).

Question 3

What is the highest number this tool supports?

Accepted Answer

This converter uses JavaScript's parseInt which safely handles integers up to 2^53 - 1. For typical computing use cases (32-bit or 64-bit values), this is more than sufficient.

Question 4

What characters are valid in hexadecimal?

Accepted Answer

Hexadecimal uses digits 0–9 and letters A–F (case insensitive). Values like FF, 1A3B, or DEADBEEF are all valid hex numbers.
