What is the difference between a binary to text translator and a binary to number translator?

Text translation turns 8-bit groups into UTF-8 characters, while the number converter treats the entire binary string as a single base-2 mathematical value.

Can I convert binary to denary and hexadecimal at the same time?

Yes, typing into the Binary field of the Number converter updates Decimal (denary), Hexadecimal, and Octal simultaneously.

What is hexadecimal used for?

Hexadecimal writes bytes in a shorter form using two digits per byte, commonly seen in color codes like #FF8800 and memory addresses.
