Mbps to MB/s Converter
Convert megabits per second (Mbps) to megabytes per second (MB/s). Includes the formula and a clear explanation of the difference.
How it works
Megabits per second (Mbps) and megabytes per second (MB/s) are both data-rate units, but they measure different things. A bit is 1/8 of a byte, so a 100 Mbps connection delivers a maximum of 12.5 MB/s in real terms.
The formula
MB/s = Mbps ÷ 8
For Kbps, first convert to Mbps (÷1,000) or directly to MB/s (÷8,000). For Gbps, multiply by 1,000 first, then divide by 8.
Examples
Common conversions:
- 10 Mbps = 1.25 MB/s
- 50 Mbps = 6.25 MB/s
- 100 Mbps = 12.5 MB/s
- 500 Mbps = 62.5 MB/s
- 1 Gbps = 125 MB/s
Frequently asked questions
Divide the number of megabits per second by 8. Because 1 byte = 8 bits,
MB/s = Mbps ÷ 8. For example, 100 Mbps = 12.5 MB/s.Because the plan is sold in megabits per second, while most download managers report megabytes per second. They are different units: 1 byte = 8 bits. 100 Mbps = 12.5 MB/s, so a 12.5 MB/s reading in your downloader means you are getting exactly the plan's full speed.
They are commonly used interchangeably. Both stand for megabits per second. Note the lowercase “b” in Mbps and Mb/s — that indicates bits, not bytes (which would be MB or MB/s, capital B).
Network speeds always use the decimal definition (1 Mbps = 1,000,000 bits per second). File sizes often use the binary definition (1 MiB = 1,048,576 bytes), but data rates do not. This converter uses the decimal definition.
1 Gbps (1000 Mbps) = 125 MB/s. Gigabit internet can transfer at 125 megabytes per second, which is enough to download a 1 GB file in about 8 seconds.
Yes. Netflix 4K requires about 25 Mbps, so 100 Mbps comfortably supports 4K streaming on multiple devices simultaneously. 100 Mbps = 12.5 MB/s of actual throughput.
