Bandwidth unit conversion
1 Gbps = 1000 Mbps = 1,000,000 Kbps; 1 byte/s = 8 bpsBandwidth is the capacity of the link, and the network is expressed in bits per second.
The network uses 1000 steps (Kbps = 103, Mbps = 106, Gbps = 109 bps), unlike storage mix 1024 and 1000.
Bandwidth (bandwidth) is the maximum rate of transmission in ** bits per second (bps)** and file size ** byte**, 1 Byte = 8 bit. So the theoretical download speed of 100 Mbps is 100 ÷8 = 12.5 MB/s. This eight-fold conversion is the most basic and easy to forget in bandwidth calculations.
However, the theoretical value is not reached,** the actual volume of throughput is about 85 per cent - 95 per cent of the theoretical bandwidth**, and losses are due to: the cost of the front of the agreement (18 bytes with a web frame, the first 20 bytes of the IP, the first 20 bytes of the TCP, which totals about 5 per cent), the delay in the processing of NAT/firewalls in the middle of the chain. Long distance links (e.g., transnational) are also affected by RTT, which is determined by `width time multipliers' -** high bandwidth + high delay, and which is not fully used if the TCP window is not large.**
| bandwidth | Theory Rate | After deduction of expenses | Download 1 GB apparition |
|---|---|---|---|
| 10 Mbps | 1.25 MB/s | Approximately 1.1 MB/s | About 15 minutes |
| 50 Mbps | 6.25 MB/s | About 5.6 MB/s | About 3 minutes |
| 100 Mbps | 12.5 MB/s | About 11 MB/s | About 1.5 minutes |
| 300 Mbps | 37.5 MB/s | Approximately 34 MB/s | About 30 seconds |
| 1 Gbps | 125 MB/s | Approximately 110 MB/s | About 9 seconds |
| 10 Gbps | 1250 MB/s | About 1.1 GB/s | About 1 second |

Frequently asked questions
Why use 1000 instead of 1024?
Network speed follows SI Decimal Prefix; only storage is traditionally used for 1024.
1 Gbps, how many MB/s?
divided by 8:1 Gbps ≈ 125 MB/s.
Bandwidth equals speed?
It is capacity; the actual speed also depends on delay, congestion and agreement.
What's the difference between bandwidth and throughput?
Bandwidth is the chain ** theoretical capacity limit** (how thick the pipe)** and throughput is ** the actual measured transmission rate** (how much water actually flowed). The gap reflects the quality of the links. Iperf, Speedtest measured throughput. If the amount of throughput is much lower than the bandwidth, this indicates bottlenecks: it may be Wi-Fi with weak signals, network failure (over five lines running less than tens of millions), light cats or routers with insufficient performance, or other server speed limits.
What's wrong with going up and down?
Home broadband is usually ** asymmetric** (a legacy of the ADSL era, as well as a cost-saving business strategy for operators): Downline 300M may be 30M or even lower. This has little impact on viewing and downloading, but can affect video calls, live streaming, web backup, and remote access to home NAS. Business lines are generally symmetrical and much higher. In case of frequent videoconferences or uploading of large documents when broadband is selected, an upward rate is specifically identified.
