Data Transfer Rate formula and what each symbol means

target = value × (factor of starting unit ÷ factor of target unit), where each factor is the unit value in bit/s.

Data Transfer Rate examples

Mbit/s to MB/s

10 Mbit/s = 1.25 MB/s.

Mbit/s to Gbit/s

10 Mbit/s = 0.01 Gbit/s.

Mbit/s to kbit/s

10 Mbit/s = 10,000 kbit/s.

How to calculate Data Transfer Rate step by step

  1. Choose the starting unit and the target unit.
  2. Enter your value.
  3. Read the converted value, plus the conversion factor in both directions.

How to read your Data Transfer Rate result

Internet plans quote bits per second (Mbit/s), while downloads show bytes per second (MB/s). Divide Mbit/s by 8 to get MB/s, for example 100 Mbit/s is 12.5 MB/s.

Common mistakes when calculating Data Transfer Rate

  • Confusing Mb (megabit) with MB (megabyte).
  • Expecting to download at the advertised line speed: protocol overhead lowers real throughput.
  • Mixing decimal (MB/s) and binary (MiB/s) units.

Data Transfer Rate FAQ

How many MB/s is 100 Mbps?

100 Mbit/s is 12.5 MB/s.

How many Mbps is 1 Gbps?

1 Gbit/s is 1,000 Mbit/s.

What is the difference between MB/s and MiB/s?

MB/s is 1,000,000 bytes per second, MiB/s is 1,048,576 bytes per second.

What is the base unit for data transfer rate?

This converter uses bit per second (bit/s) as the common base unit: every value is first converted to it and then to the target unit.

How do I convert between two data transfer rate units?

Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.

How many MB/s are in 1 megabit per second?

1 Mbit/s = 0.125 MB/s.

How many gbps are in 1 megabit per second?

1 Mbit/s = 0.001 Gbit/s.

How many kbps are in 1 megabit per second?

1 Mbit/s = 1,000 kbit/s.

Which data transfer rate units does this converter support?

It covers 12 units: bit per second (bit/s), kilobit per second (kbit/s), megabit per second (Mbit/s), gigabit per second (Gbit/s), terabit per second (Tbit/s), byte per second (B/s), kilobyte per second (kB/s), megabyte per second (MB/s), gigabyte per second (GB/s), kibibyte per second (KiB/s), mebibyte per second (MiB/s), gibibyte per second (GiB/s).

How accurate is the data transfer rate converter?

Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
