Complete Guide: Data Rate Converter
Everything you need to know about using this tool effectively
The Data Rate Converter transforms data transfer speeds between eight units: bps, kbps, Mbps, Gbps, B/s, KB/s, MB/s, and GB/s. It handles the bit-to-byte conversion (1 byte = 8 bits) and metric prefixes (kilo, mega, giga). You enter a value in one unit and see the equivalent in all others. All processing happens in the browser.
This tool converts between bits per second and bytes per second with metric prefixes. It first normalizes the input to bits per second, then converts to all other units. The bit-to-byte ratio (8 bits = 1 byte) and metric prefix factors (1000 for kilo, 1,000,000 for mega, 1,000,000,000 for giga) are applied consistently.
Understanding internet speed in download terms
Convert an advertised 100 Mbps connection to 12.5 MB/s to understand actual download speeds.
Estimating file download times
Convert your connection speed to MB/s and divide a file size by that rate to estimate download time.
Comparing network speeds
Convert between Mbps and Gbps to compare fiber, cable, and mobile data speeds on the same scale.
Planning bandwidth requirements
Convert streaming bitrates to Mbps to determine if a connection can handle multiple streams.

Divide Mbps by 8 to get approximate MB/s download speed.
Actual download speeds are typically 80-90% of advertised speeds due to overhead.
1 Mbps is sufficient for SD streaming. 5+ Mbps for HD. 25+ Mbps for 4K.
Internet providers advertise in megabits (Mbps), but file sizes are in megabytes (MB).
What is the difference between Mbps and MB/s?
Mbps is megabits per second. MB/s is megabytes per second. Since 1 byte equals 8 bits, 100 Mbps equals 12.5 MB/s. Internet providers advertise in Mbps, but download speeds are typically shown in MB/s.
How do I estimate download time?
Divide the file size in megabytes by the download speed in MB/s. For a 1 GB file at 12.5 MB/s, the download takes about 80 seconds.
Is my data sent to a server?
No. All conversion happens in your browser. Nothing is transmitted.
What units are supported?
bps, kbps, Mbps, Gbps, B/s, KB/s, MB/s, and GB/s.
Why are actual speeds lower than advertised?
Network overhead, Wi-Fi interference, server limitations, and congestion reduce actual speeds. Expect 80-90% of the advertised rate under good conditions.
