How to Use the Data Speed Converter

Enter the speed value in the Value field and select the unit you are converting from. All equivalents update instantly. The converter defaults to 100 Mbps — a common broadband speed.

Data Speed Units Explained

Data transfer speed measures how quickly data moves between devices or over a network. The base unit is bit per second (bit/s or bps).

Bit-based units

  • bit/s (bps) — the base unit. Very slow connections.
  • Kilobit/s (Kbps) — 1,000 bps. Old dial-up modems (56 Kbps).
  • Megabit/s (Mbps) — 1,000,000 bps. Standard broadband (10–1,000 Mbps).
  • Gigabit/s (Gbps) — 10⁹ bps. Fiber internet, data center networking.
  • Terabit/s (Tbps) — 10¹² bps. Backbone internet infrastructure.

Byte-based units

  • Byte/s (B/s) — 8 bps. The unit for file transfer rate shown in download managers.
  • Kilobyte/s (KB/s) — 8,000 bps. Old modem downloads.
  • Megabyte/s (MB/s) — 8,000,000 bps. SSD speeds and fast downloads.
  • Gigabyte/s (GB/s) — 8,000,000,000 bps. NVMe SSD speeds (3–7 GB/s).

Key Conversion

MB/s = Mbps ÷ 8  |  Mbps = MB/s × 8  |  1 Gbps = 125 MB/s

Worked Examples

Home internet: 200 Mbps to MB/s

200 ÷ 8 = 25 MB/s. Downloading a 1 GB file takes 40 seconds.

USB 3.0 speed: 5 Gbps to MB/s

5,000 ÷ 8 = 625 MB/s. Practical USB 3.0 speeds are typically 300–400 MB/s.

Streaming: 4K Netflix uses ~25 Mbps

25 Mbps ÷ 8 = 3.125 MB/s = 11.25 GB per hour of 4K content.

NVMe SSD: 3,500 MB/s to Gbps

3,500 × 8 = 28,000 Mbps = 28 Gbps. Top-end NVMe SSDs reach 7,000 MB/s.

Frequently Asked Questions

Why does my download speed look lower than my internet plan?
Internet plans are in Mbps (megabits), but download managers show MB/s (megabytes). Divide by 8: a 100 Mbps plan downloads at ~12.5 MB/s. Overhead and server limits reduce it further.
How fast is 5G?
5G theoretical peak speed is up to 20 Gbps. Real-world speeds range from 100 Mbps to 3 Gbps depending on signal conditions.
How long to download 1 GB at different speeds?
At 10 Mbps: 800 seconds (13 min). At 100 Mbps: 80 seconds. At 1 Gbps: 8 seconds. Formula: seconds = (file size in MB × 8) ÷ speed in Mbps.
What does latency have to do with speed?
Speed (bandwidth) determines how much data flows per second. Latency (ping) is the delay before data starts moving. High bandwidth + high latency is like a wide road with a long traffic light.
