Bit Byte Calculation Tool

The bit is the smallest unit of storage on a computer. The word is derived from the term binary digit, which means a digit that has two possible values, 0 or 1. A computer can normally not operate directly on chunks of data that are smaller than one byte. Historically the number of bits in a byte could vary depending on the computer hardware, but nowadays it is as good as always a synonym for 8 bits. The meaning of kilobyte, megabyte, gigabyte and terabyte are not always obvious. In other fields kilo normally means 1000 but the computer world has traditionally used a different definition where it means 1024. Ever wondered how many terabytes of data you could fit on your hard drive or how many kilobytes are in a gigabyte? This calculator can answer those questions and more. Simply select a unit storage type and the unit that you want it converted and press the Convert button.
