Data Transfer Rate Converter
Enter a data transfer rate, choose the current unit and select the unit you want to convert to. The calculator uses decimal data-rate prefixes and the exact relationship of 8 bits = 1 byte.

Step-by-Step Calculation
What Is a Data Transfer Rate?
Data transfer rate describes how quickly digital information can be transferred from one place to another. It is commonly expressed in bits per second or bytes per second. Network connections, internet services, storage systems and file-transfer applications use data rates to describe throughput or bandwidth.
Common units include bps, Kbps, Mbps, Gbps and Tbps for bits, and B/s, KB/s, MB/s, GB/s and TB/s for bytes. Understanding the difference between bits and bytes is especially important when comparing internet service speeds with file download speeds.
Data Transfer Rate Conversion Formula
Converted Rate = Input Rate × Source Unit Value ÷ Target Unit Value
Bit-to-byte relationship
1 byte = 8 bits
Mbps to MB/s
MB/s = Mbps ÷ 8
MB/s to Mbps
Mbps = MB/s × 8The calculator first converts the input into a common base of bits per second. It then converts that base value into the selected target unit. This approach keeps conversions consistent across all supported units.
How to Use the Data Transfer Rate Converter
- Enter the data transfer rate you want to convert.
- Select the unit of your input, such as Mbps or MB/s.
- Select the target unit for your result.
- Click Convert.
- Review the converted rate and the equivalent bps and B/s values.
- Use the step-by-step calculation to see how the result was obtained.
Mbps vs MB/s
Mbps means megabits per second, while MB/s means megabytes per second. They are not the same unit. Because one byte contains eight bits, a numerical value in Mbps is eight times the equivalent value in MB/s.
Example: 100 Mbps to MB/s
Input = 100 Mbps
Formula = 100 ÷ 8
Result = 12.5 MB/s
Internet service plans are commonly advertised in Mbps, whereas file downloads may be displayed in MB/s. Converting between the two helps you compare the numbers correctly.
Common Data Transfer Rate Conversions
| Data Rate | Equivalent | Common Use |
|---|---|---|
| 1 Mbps | 0.125 MB/s | Internet bandwidth |
| 10 Mbps | 1.25 MB/s | Internet bandwidth |
| 50 Mbps | 6.25 MB/s | Internet bandwidth |
| 100 Mbps | 12.5 MB/s | Internet bandwidth |
| 500 Mbps | 62.5 MB/s | High-speed internet |
| 1 Gbps | 125 MB/s | Gigabit networking |
| 10 Gbps | 1.25 GB/s | High-speed networking |
Bits per Second and Bytes per Second
A bit is a single binary digit, while a byte consists of eight bits. Data-transfer rates can therefore be expressed using either bit-based or byte-based units.
1 Kbps = 1,000 bps
1 Mbps = 1,000,000 bps
1 Gbps = 1,000,000,000 bps
1 Tbps = 1,000,000,000,000 bps1 KB/s = 1,000 B/s
1 MB/s = 1,000,000 B/s
1 GB/s = 1,000,000,000 B/s
1 TB/s = 1,000,000,000,000 B/sInternet Speed and Download Speed
Internet providers commonly describe connection speeds in Mbps or Gbps. A speed-test application may also report a network rate in Mbps. Download programs, browsers and operating systems can instead show file-transfer throughput in MB/s.
For example, a 1 Gbps connection corresponds mathematically to 125 MB/s under the decimal unit convention used by this calculator. This is a unit conversion, not a promise that every download will reach 125 MB/s.
Why Is My Download Speed Lower Than My Internet Speed?
The mathematical conversion between Mbps and MB/s is exact, but actual download throughput can be lower than the advertised connection rate. Real-world performance depends on the complete network path and the devices involved.
- Wi-Fi signal strength and wireless interference
- Network congestion
- Server and website capacity
- Internet routing and distance
- Network protocol overhead
- Router, modem and cable limitations
- Computer, storage and network-interface performance
Decimal vs Binary Data Units
This calculator uses decimal SI prefixes for data-transfer rates. Therefore, 1 Mbps means 1,000,000 bits per second and 1 GB/s means 1,000,000,000 bytes per second.
Binary storage units such as MiB and GiB use powers of 1,024 and are distinct from decimal MB and GB. They are not used in this converter, keeping the data-rate calculations aligned with the decimal convention.
Data Transfer Rate for Downloading Files
A data transfer rate can be used to estimate how quickly information moves, but file-transfer time also depends on file size and real-world throughput. To estimate transfer duration, the data size and effective rate must be considered together.
For example, converting a network rate from Mbps to MB/s can make it easier to compare the connection with the size and speed figures shown by a file-transfer application.
Data Transfer Rate for Networking
Network interfaces and communication links can be rated in Mbps or Gbps. Comparing these rates helps users and IT professionals understand the nominal capacity of different connections.
The calculator is useful for comparing network specifications, internet plans, speed-test results and software-reported transfer rates without manually performing the bit-to-byte conversion.
Accuracy and Limitations
The unit conversions performed by this calculator are mathematical conversions based on fixed relationships between bits, bytes and decimal prefixes. The result is not a measurement of your network.
Actual transfer performance can differ from a converted theoretical rate because of network conditions, hardware limitations, congestion, protocol overhead and the capabilities of the remote server.
Frequently Asked Questions
How do I convert Mbps to MB/s?
Divide Mbps by 8. For example, 100 Mbps ÷ 8 = 12.5 MB/s.
How many Mbps is 1 Gbps?
Using decimal data-rate units, 1 Gbps equals 1,000 Mbps.
How many MB/s is 100 Mbps?
100 Mbps is mathematically equivalent to 12.5 MB/s.
What is the difference between Mbps and MB/s?
Mbps is megabits per second, while MB/s is megabytes per second. One byte contains eight bits.
Is internet speed measured in Mbps or MB/s?
Internet plans are commonly advertised in Mbps. File-transfer applications may display speeds in MB/s.
