StorageConvert between bytes, KB/MB/GB/TB (decimal) and KiB/MiB/GiB/TiB (binary) — and end the GB-vs-GiB confusion.
Decimal — SI (×1000)
B1,000,000,000
KB1,000,000
MB1,000
GB1
TB0.001
PB1.000e-6
Binary — IEC (×1024)
B1,000,000,000
KiB976,562.5
MiB953.6743
GiB0.9313
TiB9.095e-4
PiB8.882e-7
This is why a “1 TB” disk shows as ~931 GiB: the vendor counts 10¹² bytes, your OS counts 2⁴⁰. 1 TB = 0.9095 TiB.
