FAQ
Frequently Asked Questions
How do you convert text to binary?
For each character in the text: (1) Find its ASCII/Unicode code number. (2) Convert that number to 8-bit binary. For example, 'Hi' → H=72=01001000, i=105=01101001 → 01001000 01101001₂. Spaces are character 32 = 00100000₂.
What is the binary code for 'Hello'?
'Hello' in binary is: 01001000 01100101 01101100 01101100 01101111. Each group of 8 bits represents one character: H=72, e=101, l=108, l=108, o=111. This is the standard ASCII/UTF-8 encoding used by virtually all modern computers.
Can I convert emoji to binary?
Yes, but emoji require more than 8 bits. In UTF-8, emoji use 4 bytes (32 bits). For example, the 😀 emoji (U+1F600) in UTF-8 is: 11110000 10011111 10011000 10000000₂. Our converter handles standard ASCII text; for emoji, a full Unicode encoder is needed.
What is the binary code for numbers 0-9?
The digit characters '0'-'9' have ASCII codes 48-57. In binary: '0'=00110000, '1'=00110001, '2'=00110010, '3'=00110011, '4'=00110100, '5'=00110101, '6'=00110110, '7'=00110111, '8'=00111000, '9'=00111001. Note these are different from the actual binary values of 0-9.
Why does text to binary use 8-bit groups?
8 bits (one byte) is the standard unit of character encoding. ASCII needs only 7 bits (128 characters), but the 8th bit provides an even byte boundary. Extended ASCII uses all 8 bits for 256 characters. UTF-8 builds on this byte-based approach, using 1-4 bytes per character.
How is text stored in computer memory?
Text is stored as a sequence of bytes in memory, each byte representing one character (in ASCII) or part of a character (in UTF-8). A string like 'ABC' occupies 3 bytes in memory: 0x41, 0x42, 0x43. Many programming languages add a null terminator byte (00000000) to mark the end of the string.
