Inverse Formula GB/s = MB/s × 0.001

Mental Math Shortcut

Multiply the value by roughly 1000 to calculate the equivalent amount in your head.

Common Gigabyte per Second to Megabyte per Second Calculations

5 GB/s = 5000 MB/s
10 GB/s = 10000 MB/s
50 GB/s = 50000 MB/s
100 GB/s = 100000 MB/s
500 GB/s = 500000 MB/s

Precision & Practical Use

For example, 10 GB/s = 10000 MB/s — roughly multiple unit increments.

ISPs advertise in bits per second (Mbps); file managers show bytes per second (MB/s). Remember: 1 MB/s = 8 Mbps.

How to Convert Gigabyte per Second to Megabyte per Second

How many megabyte per seconds are in one gigabyte per second?

One Gigabyte per Second (GB/s) equals 1000 Megabyte per Second (MB/s). To convert gigabyte per seconds to megabyte per seconds, multiply the gigabyte per second value by 1000.

How do I convert Gigabyte per Second to Megabyte per Second?

Multiply your gigabyte per second value by 1000 to get the result in Megabyte per Second: MB/s = GB/s × 1000. For example, 5 GB/s = 5000 MB/s.

What is the formula for converting GB/s to MB/s?

The conversion formula is MB/s = GB/s × 1000. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
