For example, in citations of main memory or RAM capacity, kilobyte, megabyte and gigabyte customarily mean 1024 (2 10), 1 048 576 (2 20) and 1 073 741 824 (2 30) bytes respectively. In the specifications of hard disk drive capacities and network transmission bit rates, decimal prefixes are used. For example, a 500-gigabyte hard drive holds 500 ...

The MMA welterweight class is therefore significantly heavier than the welterweight class of these other sports. For the sake of uniformity, many American mixed martial arts websites refer to competitors between 156 and 170 lb (71 and 77 kg) as welterweights.
