Vendors are using Flash memory decimal arithmetic: 1 MB = 1000KB, 1G = 1000 MB;
Calculated, operating system with binary arithmetic: 1 MB = 1024KB, 1 GB = 1024 MB;
128MB = approximately 115MB-125MB
256MB= approximately 230MB-250MB
512Mb = approximately 470MB-500MB
1GB = approximately 950MB-980MB
2GB = approximately 1.7G-1.9G
4GB = approximately 3.6GB-3.8GB
8GB = approximately 7.4GB-7.6GB
16GB = approximately 14GB -15GB
32GB = approximately 28GB -30GB
