Convert decimal numbers to binary format.
To convert a decimal number to binary by hand, divide it by 2 repeatedly and write down each remainder; reading the remainders from last to first gives the binary value. For example: 13 ÷ 2 = 6 r1, 6 ÷ 2 = 3 r0, 3 ÷ 2 = 1 r1, 1 ÷ 2 = 0 r1 - so 13 is 1101 in binary. This tool does the whole calculation instantly and also shows octal and hexadecimal equivalents.
Computer science students verifying homework, programmers working with bit flags and low-level data, networking students calculating subnet masks, and electronics hobbyists reading register values. Instead of manual division chains that invite mistakes, you get the answer in every base at once.
