How to Use the Data Transfer Rate Converter
Internet plans and router specs are usually listed in Mbps (megabits per second), but the download speed shown in your browser or app is often in MB/s (megabytes per second). These two units look similar but differ by a factor of 8, since 1 byte equals 8 bits. So a connection advertised as "100 Mbps" downloads files at a theoretical maximum of about 12.5 MB/s.
This converter lets you enter a value and its unit, then instantly see the equivalent in Mbps, MB/s, GB/s, and Kbps — handy for comparing internet speeds, estimating how long a large file will take to download, or checking upload/streaming requirements.
Frequently Asked Questions
Mbps (megabits per second) is commonly used for internet connection speeds, while MB/s (megabytes per second) is used for file transfer speeds. Since 1 byte equals 8 bits, MB/s is roughly 1/8 of the Mbps value.
Divide the file size in MB by the converted MB/s value to estimate download time in seconds. Actual speed may vary depending on network conditions.
