Bandwidth Converter
Convert data transfer speeds — bits per second (bps, Kbps, Mbps, Gbps) and bytes per second (B/s, KB/s, MB/s, GB/s). Critical for understanding internet plans (advertised in Mbps) vs file downloads (shown in MB/s).

📐 Formula & Method
Linear conversion
All units are stored as a multiplier against an internal base unit. To convert, the input is first scaled to the base, then divided by the target factor.
📋 How to Use
-
1
Enter the numeric value you want to convert.
-
2
Pick the source unit in the From dropdown.
-
3
Pick the target unit in the To dropdown.
-
4
Click Calculate. You will see the result, a full conversion table to every supported unit, and a list of common conversions.
💡 Key Insights
-
ISPs advertise in BITS per second (Mbps). Downloads show in BYTES per second (MB/s). Divide Mbps by 8 to get MB/s.
-
"100 Mbps" internet = 12.5 MB/s max real-world download speed.
-
Gigabit Ethernet = 1 Gbps = 125 MB/s theoretical max — overhead reduces real throughput to ~110 MB/s.
🔬 Methodology & Accuracy
Formula: Linear unit conversion with high-precision constants. All math runs client-side in your browser using IEEE-754 doubles.
Data sources: BIPM SI brochure (9th ed.); NIST SP 811 (2008 ed.); ISO 80000-1 quantities and units.
Last reviewed: January 2026 · Accuracy: Results are precise to two decimal places using IEEE-754 double-precision arithmetic. Intended for educational and planning use only.
