下面先按顺序给出所有单位：Byte、KB、MB、GB、TB、PB、EB、ZB、YB、DB、NB

1Byte = 8 Bit

1 KB = 1,024 Bytes　

1 MB = 1,024 KB = 1,048,576 Bytes　

1 GB = 1,024 MB = 1,048,576 KB = 1,073,741,824 Bytes

1 TB = 1,024 GB = 1,048,576 MB = 1,073,741,824 KB = 1,099,511,627,776 Bytes

1 PB = 1,024 TB = 1,048,576 GB =1,125,899,906,842,624 Bytes

1 EB = 1,024 PB = 1,048,576 TB = 1,152,921,504,606,846,976 Bytes

1 ZB = 1,024 EB = 1,180,591,620,717,411,303,424 Bytes

1 YB = 1,024 ZB = 1,208,925,819,614,629,174,706,176 Bytes

在现阶段的TB时代，1TB的硬盘的标准重量是670g

1NB＝2的60次方TB＝1152921504606846976TB＝1152921504606846976个1TB硬盘

总重量约为77245740809万吨 目前运载量为56万吨的 诺克耐维斯号 巨型海轮

也就是说 储存1NB的数据的硬盘要 诺克耐维斯号 最少来回拉 1 379 388 229 次 约14亿次才能将这些数据运到地点，估计1000个诺克耐维斯号都要报销。
