What is 1 Gigabytes equal to?
1 Gigabytes equals 1 GB = 1000000000 B — see the conversion table below for more magnitudes.
What is the formula for gigabytes to bytes?
Use the tool's Gigabytes → Bytes factor shown in the result details. The conversion is a fixed multiplication, so it is exact within the displayed precision.
Why does my 1 TB drive show 931 GB?
The drive is 1,000,000,000,000 bytes (1 TB decimal); the OS divides by 1024³ and reports ≈931 GiB — same bytes, different units.
What is the difference between KB and KiB?
KB (kilobyte) = 1,000 bytes (SI decimal). KiB (kibibyte) = 1,024 bytes (binary, 2¹⁰). The same pattern applies to MB/MiB and GB/GiB.
How many MB in a GB?
1,000 MB in a decimal gigabyte, or 1,024 MB if both are interpreted as binary units (which would properly be written MiB/GiB).
