flash memory vendors are using decimal arithmetic: 1mb = 1000kb, 1g = 1000mb calculated, but the operating system is using binary arithmetic: 1mb = 1024kb, 1gb = 1024mb. so there are some differences between display capacity and nominal capacity of flash memory products. however, this is allowed to exist. please do not doubt his authenticity. this is calculation difference between manufacturer and our pc; please google 'memory card capacity' to get more information.
