Loading Bandwidth Converter…
Bandwidth Converter delivers exactly what its name promises, convert between mbps, gbps, mb/s, and gb/s, fast and free. Because it belongs to ToolsMonk's converters collection, the whole workflow happens on a single page instead of being spread across separate apps or websites.
Typical jobs it handles include working out real download speed (mb/s) from an mbps connection, converting between bits and bytes per second, and estimating transfer or streaming bandwidth. The same page works on desktop, tablet, and mobile, so it is equally quick for a single urgent task and for work you repeat every week.
Bandwidth Converter is designed for people who want a practical, privacy-friendly workflow with instant results inside the larger ToolsMonk library.

Comparing internet plan speeds across units
Bandwidth Converter was built so that anyone, professional or first-time visitor, gets what the page promises (convert between mbps, gbps, mb/s, and gb/s) in seconds. Results are instant and accurate, and nothing needs to be installed or signed up for along the way.
All processing runs locally in your browser, so your files and data never leave your device. Like every tool in the Converters collection, it works across all modern browsers on desktop, tablet, and mobile: same features, same results, on every device.
Bandwidth Converter translates between data-rate units, bits and bytes per second across Kbps, Mbps, Gbps, and MB/s, and crucially clarifies the bits-vs-bytes distinction that confuses almost everyone.
Here's the heart of it: internet speeds are advertised in megabits per second (Mbps), but file sizes and download managers use megabytes (MB), and a byte is 8 bits. So a 100 Mbps connection tops out around 12.5 MB/s, divide by 8. That factor is exactly why downloads feel slower than your plan's headline number, and converting between the two removes the mystery.
Capitalisation is the trap: Mbps (lowercase b, megabits) versus MBps or MB/s (capital B, megabytes) differ by 8×. ISPs quote the bigger bits number; your transfers show the smaller bytes number. Knowing this lets you sanity-check whether you're getting the speed you pay for.
From the MB/s figure you can estimate download times (file size ÷ speed, plus real-world overhead). Conversion runs in your browser with nothing uploaded. Pair it with the Data Storage and other ToolsMonk converters for technical reference.
Divide your Mbps by 8 to get real MB/s download speed, the #1 source of 'slow internet' confusion
Watch capitalisation: Mbps = megabits, MBps = megabytes (8× bigger)
Estimate download time as file size (MB) ÷ (Mbps ÷ 8), then add overhead
