Mbps Calculator Mb S To Mbps Conversion
Your disk shows MB/s, while a network is sold in Mbps. Multiply MB/s by 8 to compare them.
Quick answer: multiply the speed in MB/s by 8. For example, 1 MB/s is 8 Mbps, 12.5 MB/s is 100 Mbps and 125 MB/s is 1,000 Mbps.
The MB/s to Mbps formula
One MB/s is 8 Mbit/s (Wikipedia: Data-rate units).
So multiply the MB/s by 8 to get Mbps.
Take 1 MB/s. Multiply by 8. The answer is 8 Mbps.
Take 12.5 MB/s. Multiply by 8. The answer is 100 Mbps.
MB/s to Mbps
MB/s means megabytes per second. One MB is 8,000,000 bits (Wikipedia: Data-rate units).
Mbps means megabits per second, or 1,000,000 bits each second (Wikipedia: Data-rate units).
The factor 8 joins the two.
How to convert MB/s to Mbps step by step
- Write down the speed in MB/s.
- Multiply it by 8.
- The answer is in Mbps.
- Check it against the chart above.
Example 1: 1 MB/s
- Start with 1 MB/s.
- 1 × 8 = 8.
- The speed is 8 Mbps.
1 MB/s = 8 Mbps
Example 2: 12.5 MB/s
- Start with 12.5 MB/s.
- 12.5 × 8 = 100.
- The speed is 100 Mbps.
12.5 MB/s = 100 Mbps
Example 3: 125 MB/s
- Start with 125 MB/s.
- 125 × 8 = 1,000.
- The speed is 1,000 Mbps.
125 MB/s = 1,000 Mbps
Multiply megabytes by 8 to get megabits (Wikipedia: Data-rate units).
MB/s to Mbps conversion table

| 12.5 MB/s | 100 Mbps | 0.1 Gbit/s |
| 50 MB/s | 400 Mbps | 0.4 Gbit/s |
| 125 MB/s | 1,000 Mbps | 1 Gbit/s |
| 500 MB/s | 4,000 Mbps | 4 Gbit/s |
The highlighted row, 12.5 MB/s, is the default of the converter. The last column gives Gbit/s.
A quick mental shortcut for MB/s to Mbps
Double three times. 5 MB/s is 10, 20, then 40 Mbps.
Or just times by 8.
What MB/s measures
MB/s means megabytes per second. One MB is 8,000,000 bits (Wikipedia: Data-rate units).
Download bars and disks show MB/s.
What Mbps measures
Mbps means megabits per second, or 1,000,000 bits each second (Wikipedia: Data-rate units).
Internet plans are sold in Mbps.
Disks and networks
A disk moving 125 MB/s needs a link of 1,000 Mbps to match.
A card moving 12.5 MB/s equals 100 Mbps.
Bits and bytes
A byte is 8 bits (Wikipedia: Byte).
That is why the number gets 8 times bigger.
Plan size for a job
To move data at 10 MB/s you need at least 80 Mbps.
Add some room for overhead.
Case matters
A lowercase b means a bit. A capital B means a byte (Wikipedia: Data-rate units).
Mbps is megabits. MB/s is megabytes.
Why multiply by 8
A megabyte holds 8 megabits (Wikipedia: Data-rate units).
So the same speed looks 8 times bigger in Mbps.
Going the other way
To go back, divide the Mbps by 8.
So 100 Mbps is 12.5 MB/s.
Check your answer
Your Mbps number should be 8 times bigger than the MB/s number.
Divide it by 8 and you should get your first number.
More values at a glance
0.5 megabytes per second is 4 megabits per second. 2 megabytes per second is 16 megabits per second. 5 megabytes per second is 40 megabits per second.
10 megabytes per second is 80 megabits per second. 25 megabytes per second is 200 megabits per second. 100 megabytes per second is 800 megabits per second.
Each answer is the input times 8. You can use the same factor for any value that is not listed here.
The unit sizes
One of the megabytes per second equals 8 megabits per second. One of the megabits per second equals 0.125 megabytes per second.
If a result looks very large or very small, compare it with these sizes before you use it.
Checking in reverse
Take 80 megabits per second and divide by 8. You get back 10 megabytes per second. If you do not, one of the numbers was typed or rounded wrongly.

|---|---|
| 1 MB/s | 8 Mbps |
| 5 MB/s | 40 Mbps |
| 12.5 MB/s | 100 Mbps |
| 50 MB/s | 400 Mbps |
| 125 MB/s | 1,000 Mbps |

Round numbers for MB/s and Mbps
Use these round numbers to check your own answer. 5 MB/s is 40 Mbps, 50 MB/s is 400 Mbps and 500 MB/s is 4,000 Mbps.
Going the other way, 50 Mbps is 6.25 MB/s, 500 Mbps is 62.5 MB/s and 5,000 Mbps is 625 MB/s.
A round trip with MB/s
Say you start with 37 MB/s. It becomes 296 Mbps. Divide that by the factor and you land on 37 MB/s again.
Now start from 2,500 Mbps instead. It becomes 312.5 MB/s, and multiplying by the factor returns 2,500 Mbps.
Disk and network examples
A disk that reads 150 MB/s moves 1,200 Mbps, which is 1.2 Gbps.
A copy speed of 50 MB/s is 400 Mbps, and 3 MB/s is 24 Mbps.
Use these to see whether a network link can keep up with your disk.
Capital B and small b
A capital B means bytes and a small b means bits, so MB/s is 8 times Mbps (Wikipedia: Data-rate units).
Mixing them up gives an error of a factor of 8.
Always write the whole unit next to the number.
Where this conversion is used
Download bars and disk speeds show megabytes per second.
Internet plans are sold in megabits per second.
People check plan speeds.
Gamers and streamers size their links.
Common mistakes to avoid
- Mixing Mbps and MB/s. Lowercase b is a bit and capital B is a byte.
- Using the wrong direction. Here 1 MB/s is 8 Mbps, so a correct answer comes out bigger than the number you start with.
- Mixing decimal and binary units. Rates use decimal prefixes.
- Using the inverse factor. The factor is 8. If you divide by it instead of multiplying, 10 MB/s becomes 1.25 Mbps instead of 80 Mbps.
