How do I convert Mbps to MB/s?

Divide the megabits per second by 8, because one byte is 8 bits. So 100 Mbit/s (Mbps) equals 12.5 MB/s. The converter applies the ÷8 automatically when you go from a bit unit to a byte unit.

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

Mbit/s (megabits per second, often written Mbps) measures bits, while MB/s (megabytes per second) measures bytes. Since a byte is 8 bits, MB/s is one eighth of the same figure in Mbit/s.

What is the difference between kB/s and KiB/s?

kB/s uses the decimal (SI) kilo of 1,000 bytes, while KiB/s uses the binary (IEC) kibi of 1,024 bytes. The same applies to MB vs MiB and GB vs GiB. This converter supports both so you can match whichever your software reports.

How fast can I download a 1 GB file on 100 Mbps?

At 100 Mbit/s the throughput is 12.5 MB/s, so 1 GB (1,000 MB) takes about 80 seconds at the theoretical maximum, before real-world overhead. Use a dedicated download-time calculator for a full estimate.

Is my data sent anywhere?

No. Every conversion runs entirely in your browser with fixed factors. Nothing you type is uploaded or stored.

What is the Data Transfer Rate Converter?

Free data transfer rate converter. Convert between bit/s, kbit/s, Mbit/s, Gbit/s, Tbit/s and byte-based B/s, kB/s, MB/s, GB/s plus binary KiB/s, MiB/s, GiB/s. Handles the 8-bits-per-byte gap correctly. Runs entirely in your browser. It runs free in your browser on Gera Tools, with nothing uploaded.

A data transfer rate converter for internet speeds, disk throughput and network bandwidth. It moves between bit-based units (bit/s, kbit/s, Mbit/s, Gbit/s, Tbit/s) and byte-based units (B/s, kB/s, MB/s, GB/s), including the binary IEC units (KiB/s, MiB/s, GiB/s) — and it handles the two conversions people get wrong: the 8-bits-per-byte gap and the 1000-vs-1024 prefix difference.

How it works

Every rate is expressed in a single baseline of bits per second, then divided into whatever unit you ask for. One byte is 8 bits, so a byte-per-second is 8 bit/s and a megabyte-per-second is 8 megabits-per-second. Decimal prefixes step by 1,000 (kbit, Mbit, Gbit; kB, MB, GB) while the “i” prefixes step by 1,024 (KiB, MiB, GiB), which is why your operating system’s “MB” can differ from a drive maker’s “MB”. Using one bits-per-second pivot keeps the whole grid consistent no matter which pair you pick.

The classic trap is reading an internet plan sold in megabits (Mbps) as if it were megabytes. A 100 Mbit/s line is only 12.5 MB/s, because you divide by 8. This converter does that ÷8 automatically the moment you convert from a bit unit to a byte unit. Everything is computed in your browser with fixed factors, so nothing you type leaves your device.

Worked example

You have a 500 Mbit/s connection and want the byte throughput. Enter 500, set From to Mbit/s and To to MB/s: the tool divides by 8 to give 62.5 MB/s. The grid also shows 0.5 Gbit/s and about 59.6 MiB/s (dividing by 1,024² instead of 1,000,000). Press Swap and 62.5 MB/s reads straight back as 500 Mbit/s.

Conversion reference

From	Equals
1 byte/s	8 bit/s
1 Mbit/s	0.125 MB/s
100 Mbit/s	12.5 MB/s
1 Gbit/s	125 MB/s
1 MB/s	8 Mbit/s
1 MiB/s	8.389 Mbit/s
1 GB/s	8 Gbit/s

All figures use exact factors. For how long a specific file will take at a given speed, use a download-time calculator, which also accounts for real-world overhead.
