一GB等于多少兆?

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

1024M

K代表Kilo,千的意思;B代表Byte,字节的意思.
所以KB就是千字节.一般做为计算机中存储容量的大小单位.
1KB=2^10B=1024B
M＝mega 兆，百万
G＝giga 十亿
Gb千兆字节
