Convert numbers instantly — type a value, pick your units, and every other common unit updates live below. 100% free, runs entirely in your browser, no sign-up.
Every unit below updates live from the value you enter in the "From" field above.
Computers ultimately store everything in binary (base 2), but binary numbers get long fast, so developers use hexadecimal (base 16) and, less often today, octal (base 8) as compact shorthand — every hex digit maps cleanly to exactly 4 binary digits. This converter works on whole (integer) numbers only; decimals and negative numbers aren't supported.
