In this article, we’ll show you how to convert data transfer rates from megabits per second (Mbps) to terabytes per second (TB/s or TBps). We will cover essential definitions, provide examples, share relevant formulas, and present tables, along with answers to common questions.
Definitions of Mbps and TB/s
Let’s get started by understanding the key definitions and differences between Mbps and TB/s. Understanding these terms will allow you to perform conversions confidently.
Both units use International System of Units (SI) prefixes to simplify measuring and comparing data transfer rates. This standardization aids in conversions and understanding data transfer.
The table below shows all the SI prefixes and the associated symbols, multipliers, and colloquials.
What is Megabits per second (Mbps)?
A Megabit per second (Mbps) is a unit of measurement for data transfer rates used when streaming or transferring data over the internet or network via a high-speed connection such as 4G mobile network, cable, or optical fiber connection.
It is part of the International System of Units (SI)[1] and uses decimal multiples of bits (106). It has symbols or abbreviations such as Mbps, Mb/s, Mbit/s, or Megabit/s.
One megabit per second equals one million bits per second or 1,000,000 bps or 0.000000125 TB/s (1,000,000 ÷ 8,000,000,000,000).
What is Terabytes per second (TB/s)?
A Terabyte per second (TB/s) measures data transfer rates during transfers between internal drives or over a local computer network using high-speed SSDs (Solid State Drives) and terabit networks.
It has symbols or abbreviations such as TBps, TB/s, Tbyte/s, or Terabyte/s.
Since a byte equals eight bits (1B = 8b), a terabyte per second equals eight terabits per second (1 TB/s = 8 Tbps).
In the International System of Units (SI), data storage and transfer rate units uses the decimal multiples of bytes (1012), which means:
1 TB/s = 1012 B/s = 1,000,000,000,000 B/s1 TB/s = 8 × 1012 = 8,000,000,000,000 bps1 TB/s = 8 x 1012 ÷ 106 = 8,000,000 Mbps
Please refer to the FAQs section to find out when 1 TB/s = 8 × 220 = 8,388,608 Mbps.
Mbps to TB/s formula
Let’s take a closer look at the conversion formula so you can carry out these conversions independently, whether you're using a calculator or doing it manually with pencil and paper.
Multiplication formula for converting data transfer rate (R) from Mbps to TB/s: R(TB/s) = R(Mbps) × (1.25 × 10-7)
Or remember one of the following Mbps-to-TBps conversion factors:
1 Mbps = 1/8 × 10-6 TB/s1 Mbps = 1.25 × 10-7 TB/s1 Mbps = 0.000000125 TB/s
Examples
Now, let's take a look at an example that illustrates the calculations required to convert from megabits to terabytes per second (Mbps to TB/s).
Convert 500 Mbps to TB/s
Write down 500 Mbps and multiply it by the Mbps-to-TBps conversion factor: 1/8 × 10-6 or 0.000000125 to get the rate value R in TB/s:
So, 500 megabits per second is equal to 0.0000625 terabytes per second.
Alternatively, you can use our calculator by entering 500 into the Mbps box, and you instantly get the rate in TBps or TB/s, in this case, 0.0000625 TBps.

FAQs
Is 1 Mbps or 1 TB/s faster?
A terabyte per second (TB/s) is 8,000,000 times faster than a megabit per second (Mbps). A bit per second (bps) is the smallest unit for measuring data transfer rates. Here are the relationships between the units.
1 Mbps = 1 × 106 bps = 1,000,000 bps1 TB/s = 8 × 1012 bps = 8,000,000,000,000 bps1 TB/s = 8,000,000,000,000 ÷ 1,000,000 = 8,000,000 Mbps1 Mbps = 1,000,000 ÷ 8,000,000,000,000 = 0.000000125 TB/s
How to convert from Mbps to TB/s?
To convert a data transfer rate from megabits per second (Mbps) to gigabytes per second (TB/s), follow the simple steps below:
- Write down the rate value in
megabits per second (Mbps). - Multiply it by the value of a
Mbps-to-TBpsconversion factor:1/8 × 10-6. - The result from multiplication is the value of the transfer rate in
terabytes per second (TB/s).
Is 1 terabyte per second (TB/s) equal to 1,024 gigabytes or 1,000 gigabytes per second?
1 TB/s can be defined as either 1,000 GB/s (SI convention) or 1,024 GB/s (binary convention), depending on which standard you choose to use.
In the binary system, where used by most computer operating systems (e.g. Windows, macOS, and Linux), units are powered by two instead of 10, which means:
1 TB/s = 1 × 210 Gigabyte/s = 1,024 GB/s1 TB/s = 8 × 210 Gigabit/s = 8,192 Gbps1 TB/s = 8 × 220 Megabit/s = 8,388,608 Mbps1 TB/s = 1 × 240 byte/s = 1,099,511,627,776 B/s1 TB/s = 8 x 240 bit/s = 8,796,093,022,208 bps
To avoid this confusion, the International Electrotechnical Commission (IEC)[2] introduced new prefixes for the binary system.
The table below lists all binary prefixes, their symbols, and multipliers for the byte unit.
So, instead of using Terabyte per second (TB/s), you can use Tebibyte per second (GiB/s or GiBps) to refer to the binary system specifically:
1 TiB/s = 1 × 210 Gibibyte/s = 1,024 GiB/s1 TiB/s = 1 × 220 Mebibyte/s = 1,048,576 MiB/s1 TiB/s = 1 × 240 byte/s = 1,099,511,627,776 B/s1 TiB/s = 8 x 240 bps = 8,796,093,022,208 bps
