Data Transfer Rate Converter — Translate internet plan speeds between bps, Kbps, Mbps, Gbps and download rates in B/s, KB/s, MB/s so 100 Mbps = 12.5 MB/s.
1 Gigabits per second = 1,000 Megabits per second
1 Gbps = 1,000 MbpsUnit

A data-transfer-rate converter translates between the way internet speed is advertised (megabits per second, Mbps, Gbps) and the way file downloads actually display progress (megabytes per second, MB/s). This matters because 1 byte = 8 bits, so a '100 Mbps' connection will pull files at only about 12.
Formula
1 byte = 8 bits. MB/s = Mbps ÷ 8. So 100 Mbps = 12.5 MB/s. 1 Gbps = 125 MB/s.Your 100 Mbps PTCL plan should take about 4 minutes to download a 3 GB game patch — if it takes an hour, your ISP is bottlenecking somewhere or your WiFi is dropping signal between the router and your laptop. The single most universally confusing conversion in consumer tech is Mbps (megabits per second, what ISPs advertise) versus MB/s (megabytes per second, what Chrome and Steam show during a download). They differ by a factor of 8 because 1 byte = 8 bits, which means a "100 Mbps" plan downloads at only 12.5 MB/s real speed. ISPs use bits because the bigger number sells better; software uses bytes because files are byte-addressed. Both are technically correct; neither side is going to switch. Real-world Pakistani internet rarely hits its advertised number — peak-hour congestion (7-11pm in most cities), WiFi distance, and source server speed each shave off 10-30 percent. A 100 Mbps Stormfiber connection might do 92 Mbps at 3am and 45 Mbps at 9pm streaming Netflix while someone else is on PUBG. Run a speed test at multiple times of day before deciding your plan is genuinely slow versus just being honest about typical conditions.
A data-transfer-rate converter translates between the way internet speed is advertised (megabits per second, Mbps, Gbps) and the way file downloads actually display progress (megabytes per second, MB/s). This matters because 1 byte = 8 bits, so a '100 Mbps' connection will pull files at only about 12.5 MB/s — a surprise for many users. This tool handles the conversion cleanly so you can estimate realistic download times, compare internet plans, and size network equipment.
Bits and bytes are different units. Network gear and service providers advertise in bits per second because hardware signalling is bit-level. File systems and software display progress in bytes per second because files are byte-addressed. Converting between the two is just dividing or multiplying by 8. In real-world use, protocol overhead (TCP/IP headers, retransmissions) eats 5–15% of raw capacity, so a 100 Mbps plan typically delivers 85–95 Mbps of usable throughput.
Internet and network transfer rates. Remember: 1 byte = 8 bits, so MB/s = Mbps ÷ 8.
| Mbps | MB/s | Gbps | Kbps | Good for |
|---|---|---|---|---|
| 5 | 0.625 | 0.005 | 5,000 | HD (1080p) streaming |
| 10 | 1.25 | 0.01 | 10,000 | Basic home use |

| 100 | 12.5 | 0.1 | 100,000 | Gaming, remote work |

25 Mbps = 3.1 MB/s, enough to stream Netflix 4K comfortably on a single device.
100 Mbps downloads a 1 GB game update in about 80 seconds.
A gigabit (1,000 Mbps / 125 MB/s) connection can fill a typical 32 GB USB drive in 4 minutes.
3G mobile data tops out around 2–7 Mbps; 5G can deliver 200–1,000 Mbps under good conditions.
A 100 Mbps internet plan delivers up to 12.5 MB/s — so a 1 GB file takes at least 80 seconds to download.
A 1 Gbps fiber connection moves data at 125 MB/s peak — allowing an 8 GB game update in about one minute.
Typical 4G LTE in Pakistan delivers 20–50 Mbps, equal to 2.5–6.25 MB/s — enough for 4K streaming but slow for large downloads.
Theoretical 5G peaks near 1 Gbps, but real-world 5G in most cities averages 100–300 Mbps.
Old Wi-Fi (802.11n) tops out at 600 Mbps theoretical; real-world throughput at range is usually 50–100 Mbps.
A USB 3.0 drive moves data at 5 Gbps (625 MB/s theoretical) — roughly 10× faster than USB 2.0.
