Each binary digit represents a power of two, so you add up the powers of two wherever there is a 1, and the total is the decimal value. The browser-based number base converter does this instantly and shows the binary, octal, decimal and hex forms together, all in your browser.
Binary is base 2, so each position is a power of two, doubling from right to left: 1, 2, 4, 8, 16 and so on. To convert to decimal, add the place values wherever the binary digit is 1. For example, 1011 is 8 plus 0 plus 2 plus 1, which equals 11 in decimal. The rightmost digit is the ones place, and every step left is worth twice as much.
The number base converter lets you type a value in binary, octal, decimal or hexadecimal and instantly shows all four representations. That is handy when you are working with byte values, colour codes or low-level data and need to jump between bases. It runs entirely in your browser, so nothing you enter is uploaded.
