Megabytes per second to gigabytes per second converter
Convertersconversion pair
Convert MB/s to GB/s instantly: 1,000 MB/s make 1 GB/s. Storage throughput, fast copies and the point where the disk stops being the bottleneck.
a thousand megabytes a second is one gigabyte, and a very good day.

pro tips
Divide by 1,000, not 1,024. Storage marketing uses decimal prefixes, even when the operating system later shows GiB.
A 3,500 MB/s SSD is 3.5 GB/s. The number did not change; the unit got bigger.
If a copy starts strong and then settles, the first figure was probably cache and the second is the real sustained rate.
what it does
One gigabyte per second is 1,000 megabytes per second, so the conversion is a divide by a thousand. It is the storage-side counterpart to the network prefixes, and it uses the same decimal step.
This scale shows up in NVMe drives, RAID arrays, memory cards and local copies. A drive rated at 3,500 MB/s is 3.5 GB/s, which sounds less dramatic and is exactly the same hardware.
Practical anchors: 500 MB/s is 0.5 GB/s, 2,000 MB/s is 2 GB/s, and 7,000 MB/s is 7 GB/s. A 20 GB file copied at 2 GB/s takes about ten seconds, before the file system has its say.
Enter a megabyte-per-second value and the widget answers in gigabytes per second immediately. Copy the result, or swap to the inverse page when a spec sheet is already in GB/s.
quick answers
Is 1 GB/s the same as 1,000 MB/s?
Yes, in decimal storage units. The operating system may display the same drive in GiB, where the numbers look smaller.
Why do NVMe drives quote MB/s instead of GB/s?
Because the bigger number looks better on a specification sheet. The drive is the same; only the presentation changes.
Does a faster drive make my computer faster?
It makes large reads and writes faster. Boot time, app launches and small random operations depend on other factors too.
