bit、Byte、KB、MB、GB、TB、PB、EB、ZB、YB、BB、NB、DB之間的換算關係是什麼？

它們按照進率1024（2的十次方）來計算：   
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 TB = 1,024 GB = 1,048,576 MB 
1 PB = 1,024 TB = 1,048,576 GB 
1 EB = 1,024 PB = 1,048,576 TB 
1 ZB = 1,024 EB = 1,048,576 PB
1 YB = 1,024 ZB = 1,048,576 EB 
1 BB = 1,024 YB = 1,048,576 ZB 
1 NB = 1,024 BB = 1,048,576 YB 
1 DB = 1,024 NB = 1,048,576 BB
