What is the actual capacity of 1TB micro sd card?
It's normal to have 931g hard disk with 1TB capacity.
As we all know, binary system is used in the computer, so that the calculation of capacity in the operating system is based on every 1024, 1KB for every 1024 bytes, 1MB for every 1024KB, 1GB for every 1024MB, 1TB for every 1024gb.
IEC standard is adopted under Windows platform,
1GB=1024MB，1MB=1024KB，1KB=1024Byte；
Linux is based on Si standard,
1GB=1000MB，1MB=1000KB，1KB=1000B。
1. 1TB theoretical value: 1TB = 1024g, 1GB = 1024MB.
2. 1TB factory value: 1TB = 1000g, 1g = 1000m.
3. 1TB actual value: 1TB = 1000x0.9313gb = 931g (approximate value), 1g = 931m (approximate value).
