Network speed (bandwidth, rate) measures how fast data is transmitted over networks. Units are split into bit rate (bit/s) and byte rate (Byte/s), where 1 byte = 8 bits. Different products and tools use different units; understanding conversions helps evaluate performance and cost.
Common units and conversions
- bps: base unit.
- kbps: 1 kbps = 1,000 bps.
- Mbps: 1 Mbps = 1,000,000 bps.
- Gbps: 1 Gbps = 1,000,000,000 bps.
- Tbps: 1 Tbps = 1,000,000,000,000 bps.
- Bps: 1 Bps = 8 bps.
- kBps: 1 kBps = 8,000 bps.
- MBps: 1 MBps = 8,000,000 bps.
- GBps: 1 GBps = 8,000,000,000 bps.
- TBps: 1 TBps = 8,000,000,000,000 bps.
Typical usage
- Home broadband: 100/300/500/1000 Mbps → ≈ 12.5/37.5/62.5/125 MBps
- 4G/5G: peaks 100 Mbps–2 Gbps
- Enterprise/DC: 1/10/40/100 Gbps
- Cloud: billed in Mbps or GBps
- Downloads: UI often shows MBps or kBps
- Video streaming: 1080p ~5 Mbps; 4K ≥25 Mbps
- Storage I/O: MBps or GBps
Notes
- ISP uses bits (Mbps); download tools show bytes (MBps). Divide by 8.
- Mind case: B = byte, b = bit.
- Real speeds vary; theoretical only.
- Networking uses decimal (1k=1000); storage may use binary (KiB).
Quick reference
| Unit | Conversion | Typical use |
| 1 Mbps | = 1,000,000 bps = 125,000 Bps = 125 kBps = 0.125 MBps | Home broadband, Wi‑Fi |
| 100 Mbps | = 100,000,000 bps = 12.5 MBps | Mainstream subscription |
| 1 Gbps | = 1,000,000,000 bps = 125 MBps | Gigabit link |
| 1 MBps | = 8,000,000 bps = 8 Mbps | Download display |
| 1 kBps | = 8,000 bps = 8 kbps | Legacy tools |
Tip: To convert Mbps to MBps, divide by 8. E.g., 100 Mbps → 12.5 MBps.
