常见java各种单位换算

linux内存大小换算：

2g(2048mb/1024)=2048mb(2097152kb/1024)=2097152kb(2147483648bytes/1024)=2147483648bytes

各进制转换bit（位）bytes（字节）M、G、TB、PB

1Byte = 8 Bit 

1KB    = 1,024 Bytes

1MB   = 1,024 KB = 1,048,576 Bytes

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

1TB    = 1,024 GB = 1,048,576 MB = 1,099,511,627,776 Bytes

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

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

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

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