What is a data transfer rate converter?
A data transfer rate converter converts between units of speed used for networks and storage: bits per second (bps, Kbps, Mbps, Gbps, Tbps) and bytes per second (B/s, KB/s, MB/s, GB/s, TB/s). One byte = 8 bits, so 1 MB/s = 8 Mbps. This tool also shows total data transferred over a given time—enter a speed (e.g. 1 Gbps) and see how much data flows in 1 minute, 1 hour, 1 day, or 1 month (30 days). That makes it useful for capacity planning, backup windows, and understanding ISP or link specs.
SI vs IEC: Byte multiples can use decimal (SI) or binary (IEC). SI: 1 KB/s = 1,000 B/s, 1 MB/s = 1,000² B/s. IEC: 1 KiB/s = 1,024 B/s, 1 MiB/s = 1,024² B/s. A Megabyte (MB) is 1,000² bytes; a Mebibyte (MiB) is 1,024² bytes. The converter lets you switch so you match your OS (often binary) or your provider (often decimal).
Why time-based conversion matters
Knowing “1 Gbps” is less useful than knowing “at 1 Gbps I can transfer about 450 GB in 1 hour.” This converter multiplies your speed by time: data = speed × time. So 1 Gbps × 3,600 seconds = 3.6×10¹² bits = 450 GB (decimal) in one hour. Use it to estimate download times, backup windows, or how much data a link can move in a day or month.
Real-world examples: at 350 Mbps (Starlink V3), you move about 157.5 GB in 1 hour. At 8 Gbps (Google Fiber), about 3.6 TB in 1 hour. At 100 Gbps (AWS Direct Connect), about 45 TB in 1 hour. The time-based view helps you compare ISP tiers, plan migrations, and sanity-check backup or sync windows.
How to convert bps to Mbps, Gbps, or MB/s (step by step)
To convert data transfer rates manually: express the speed in a single base (e.g. bits per second), then divide by the target unit's factor. For bits: 1 Kbps = 1,000 bps, 1 Mbps = 1,000,000 bps, 1 Gbps = 1,000,000,000 bps. So 350 Mbps = 350 × 10⁶ bps. To get bytes per second from bits per second, divide by 8: 1 Gbps = 10⁹ bps = 125 MB/s (decimal). This converter does that for every unit and shows equivalent speeds in one place.
Data transferred = speed × time. 1 Gbps × 3,600 s = 450 GB (decimal) in one hour.
Use the Quick Load dropdown to plug in common link speeds (Starlink, Google Fiber, Wi‑Fi 7, 5G, AWS Direct Connect), then read the Total data transferred section for 1 minute, 1 hour, 1 day, and 30 days. Copy the summary to share or compare plans.
Bits vs bytes: why both?
Bits per second (bps, Kbps, Mbps, Gbps, Tbps) are how network and modem speeds are usually advertised; bytes per second (B/s, KB/s, MB/s, GB/s, TB/s) are how file transfers and storage tools often report throughput. A byte is 8 bits, so 100 Mbps = 12.5 MB/s. This converter supports both so you can go from ISP specs to file-transfer equivalents without mental math.
When you toggle SI (1000) vs IEC (1024), only the byte units change (KB/s vs KiB/s, MB/s vs MiB/s). Bit units are always decimal. Match SI to manufacturer/ISP labels and IEC to OS or binary-oriented tools.
Quick-load presets
Presets load common link speeds in one click: Starlink V3 (350 Mbps), 5G Advanced (1.2 Gbps), Standard Home Fiber (1 Gbps), Google Fiber (8 Gbps), Wi‑Fi 7 (Theoretical Max) (46 Gbps), AWS Direct Connect (100 Gbps). Use them to quickly compare total data over 1 min, 1 hour, 1 day, or 30 days and to calibrate expectations for home, office, or cloud links.
Common use cases: who uses a data transfer rate converter?
Network and sysadmins use it to translate ISP or link specs (e.g. 10 Gbps) into bytes per second and total data over a backup or sync window. Developers and DevOps use it to estimate transfer times for large uploads or migrations. Consumers use it to compare broadband plans (e.g. 350 Mbps vs 1 Gbps) and to see how much data they can move in an hour or a day. Cloud and colo teams use it for Direct Connect or cross-region transfer planning. All calculations run in your browser—no data is sent to a server—so you can use it for internal or sensitive estimates.
Data Transfer Rate FAQ
? How do I convert Mbps to MB/s?
1 byte = 8 bits, so divide megabits per second by 8 to get megabytes per second. 100 Mbps = 12.5 MB/s (decimal). Use the converter and choose bits or bytes; it does the math for any unit.
? What is the difference between MB/s and MiB/s?
MB/s (Megabyte per second) uses 1,000² = 1,000,000 bytes per second (SI). MiB/s (Mebibyte per second) uses 1,024² = 1,048,576 bytes per second (IEC). So 1 MiB/s is about 1.05 MB/s. Toggle SI vs IEC in the tool to match your source.
? How much data can I transfer in 1 hour at 1 Gbps?
1 Gbps = 10⁹ bits per second. In 1 hour (3,600 s): 3.6×10¹² bits = 450 GB (decimal) or about 419 GiB (binary). Enter 1 Gbps in the converter and read the “1 hour” row.
? Why does my OS show different sizes than the converter?
Many operating systems and tools report in binary (KiB, MiB, GiB). ISPs and marketing often use decimal (KB, MB, GB). Switch the converter to IEC (1024) when comparing to OS or binary-based tools.
? Is 1 Gbps the same as 1 gigabyte per second?
No. 1 Gbps = 1 gigabit per second = 10⁹ bits per second. 1 GB/s = 1 gigabyte per second = 8 × 10⁹ bits per second. So 1 GB/s = 8 Gbps. The converter shows both; choose the unit that matches your source (e.g. ISP "1 Gbps" vs file transfer "125 MB/s").
? How do I convert Kbps to Mbps or Gbps?
Divide by 1,000 for each step: 1,000 Kbps = 1 Mbps, 1,000 Mbps = 1 Gbps. So 350,000 Kbps = 350 Mbps. Enter your value in any unit in the converter and select the target unit from the dropdown; it shows the equivalent in all supported units and the total data over 1 min, 1 hour, 1 day, and 30 days.
