Convert Between Data Transfer Speed Units
Our Data Transfer Speed Converter helps you translate between different units of digital speed, such as megabits per second (Mbps) and megabytes per second (MB/s).
What is a Data Transfer Speed Converter?
A Data Transfer Speed Converter is a utility for translating the rate of data flow between different units. It clarifies the often-confusing relationship between bits and bytes, allowing you to easily convert from speeds like megabits per second (Mbps), used to advertise internet plans, to megabytes per second (MB/s), which is how download speeds are typically displayed in your browser or applications.
How It Works: Bits vs. Bytes
The calculator is based on the fundamental relationship in digital data:
1 Byte = 8 Bits
When you enter a value, the calculator first converts it to a base unit (bits per second) and then calculates all other equivalent speeds. It uses the decimal prefixes (kilo=1000, mega=1,000,000) which is standard for data transfer rates.
Frequently Asked Questions
What is the difference between megabits (Mb) and megabytes (MB)?
The key difference is that a bit is the smallest unit of data, while a byte is a group of 8 bits. Therefore, megabits per second (Mbps) measures data transfer speed, while megabytes (MB) measures file size. To convert Mbps to MB/s, you divide by 8.
If I have a 1 Gbps internet connection, what is my download speed in MB/s?
A 1 Gigabit per second (Gbps) internet connection is equal to 1,000 Megabits per second (Mbps). To find the speed in Megabytes per second (MB/s), you divide by 8. So, 1000 Mbps / 8 = 125 MB/s. This is the maximum theoretical download speed.
Why are internet speeds advertised in Mbps instead of MB/s?
Internet service providers (ISPs) advertise speeds in megabits per second (Mbps) primarily for marketing reasons—the number is larger and sounds more impressive. Since there are 8 bits in a byte, a 100 Mbps connection is equivalent to a 12.5 MB/s connection.
