About This Converter:
- All conversions use bits per second (bps) as the base unit.
- SI (decimal): 1 Kbps = 1,000 bps; 1 Mbps = 1,000,000 bps. Used by ISPs and network equipment manufacturers.
- IEC (binary): 1 Kibps = 1,024 bps; 1 Mibps = 1,048,576 bps. Used in some technical and OS contexts.
- Bits vs Bytes: 1 byte = 8 bits. Internet speeds are quoted in Mbps (megabits); file sizes are in MB (megabytes).
- All calculations run locally in your browser — your data is never sent to any server.

Common Use Cases for Data Transfer Rate Converter
Understanding Internet Speed Plans
Consumers use the data transfer rate converter to understand their internet plan. ISPs advertise speeds in Mbps (megabits per second), but download speeds in browsers and apps are shown in MB/s (megabytes per second) — 100 Mbps = 12.5 MB/s.
Estimating File Download & Upload Times
Users use the data transfer rate converter to estimate how long a file will take to download or upload. Knowing your connection speed in MB/s and the file size in MB gives an accurate time estimate.
Network Engineering & Infrastructure
Network engineers use the data transfer rate converter to compare bandwidth specifications across equipment. Server NICs, switches, and routers are rated in Gbps, while WAN links may be specified in Mbps or Kbps.
Comparing ISP & Mobile Data Plans
Consumers comparing broadband, fibre, and mobile data plans use the data transfer rate converter to put all speeds on the same basis. 5G speeds (up to 10 Gbps theoretical) vs. fibre (1 Gbps) vs. ADSL (20 Mbps) are easier to compare in a single unit.
Video Streaming & Bitrate Planning
Content creators and streaming engineers use the data transfer rate converter to plan video bitrates. 4K streaming requires ~25 Mbps; 1080p requires ~8 Mbps. Converting between Mbps and KB/s helps configure encoding software.
Storage & Backup Transfer Planning
IT professionals use the data transfer rate converter to estimate backup and data migration times. A 1 TB backup over a 1 Gbps link takes approximately 8,000 seconds (≈ 2.2 hours) — the converter makes these calculations instant.
Understanding Data Transfer Rate Units
What is a Data Transfer Rate Converter?
A data transfer rate converter converts bandwidth and throughput measurements between different units — for example, Mbps to MB/s, Gbps to Mbps, or Kbps to bps. Data transfer rates are measured in bits per second (bps) or bytes per second (B/s), with SI decimal prefixes (Kilo = 1,000; Mega = 1,000,000) or IEC binary prefixes (Kibi = 1,024; Mebi = 1,048,576). Our browser-based data transfer rate converter supports 16 units across all four systems with a grouped all-at-once conversion table and quick-convert buttons.
How Our Data Transfer Rate Converter Works
- Enter a Data Rate Value: Type any data rate value in the input field. The all-at-once conversion table updates instantly as you type — no button click needed. Use the quick-convert buttons to set the most popular unit pairs in one click.
- Select From and To Units: Choose your source unit from the From dropdown and your target unit from the To dropdown. Use the swap button (⇄) to reverse the conversion direction instantly.
- Instant Browser-Based Conversion: Click Convert for the primary result card. All conversions use bits per second (bps) as the base unit and run entirely in your browser — your data is never sent to any server.
Bits vs Bytes — The Key Distinction
- 1 byte = 8 bits. This is the most important conversion in data rates. Internet speeds are advertised in Mbps (megabits per second), but file download speeds in browsers and apps are shown in MB/s (megabytes per second). 100 Mbps ÷ 8 = 12.5 MB/s.
- SI (decimal) prefixes: 1 Kbps = 1,000 bps; 1 Mbps = 1,000,000 bps; 1 Gbps = 1,000,000,000 bps. Used by ISPs, network equipment manufacturers, and most consumer-facing specifications.
- IEC (binary) prefixes: 1 Kibps = 1,024 bps; 1 Mibps = 1,048,576 bps; 1 Gibps = 1,073,741,824 bps. Used in some technical standards and operating system contexts to avoid ambiguity.
- Practical example: A 1 Gbps fibre connection = 1,000 Mbps = 125 MB/s = 119.2 MiB/s. The data transfer rate converter shows all of these simultaneously in the conversion table.
Important Notes
The data transfer rate converter shows theoretical maximum rates based on the unit conversion. Actual real-world throughput is always lower due to protocol overhead, network congestion, hardware limitations, and other factors. For example, a 100 Mbps connection typically delivers 80–95 Mbps of actual throughput. When comparing ISP plans, always check whether the advertised speed is the download speed, upload speed, or both — they are often different.

Frequently Asked Questions About Data Transfer Rate Converter
A data transfer rate converter converts bandwidth and throughput measurements between different units — bps, Kbps, Mbps, Gbps, Tbps, and their byte equivalents. Our data transfer rate converter supports 16 units across SI decimal and IEC binary systems with a grouped all-at-once conversion table — all running locally in your browser with no signup required.
Divide Mbps by 8 to get MB/s. For example, 100 Mbps ÷ 8 = 12.5 MB/s. This is because 1 byte = 8 bits. Internet speeds are advertised in Mbps (megabits), but download speeds in browsers and apps are shown in MB/s (megabytes).
Multiply MB/s by 8 to get Mbps. For example, 50 MB/s × 8 = 400 Mbps. Use the quick-convert button "MB/s → Mbps" in the data transfer rate converter for instant results.
Mbps = megabits per second; MB/s = megabytes per second. Since 1 byte = 8 bits, 1 MB/s = 8 Mbps. ISPs advertise speeds in Mbps, while file transfer speeds are shown in MB/s. This difference often causes confusion — a 100 Mbps plan delivers about 12.5 MB/s of actual file transfer speed.
SI (decimal) prefixes: 1 Kbps = 1,000 bps; 1 Mbps = 1,000,000 bps. IEC (binary) prefixes: 1 Kibps = 1,024 bps; 1 Mibps = 1,048,576 bps. ISPs and network equipment use SI prefixes. Some operating systems and technical standards use IEC binary prefixes to avoid ambiguity.
1 Gbps = 1,000 Mbps = 125 MB/s (SI decimal). In IEC binary, 1 Gbps ≈ 119.2 MiB/s. A 1 Gbps fibre connection can theoretically download a 1 GB file in about 8 seconds.
100 Mbps = 12.5 MB/s. A 1 GB (1,000 MB) file would take approximately 1,000 ÷ 12.5 = 80 seconds (about 1.3 minutes) at maximum theoretical speed. Real-world download times are typically 10–20% longer due to protocol overhead.
