SI unit: -
Decimal (SI) vs Binary (IEC):
Networking and telecommunications use SI decimal prefixes: 1 kbit/s = 1,000 bit/s, 1 Mbit/s = 1,000,000 bit/s (powers of 10).
Some hardware engineering and memory contexts use IEC binary prefixes: 1 Kibit/s = 1,024 bit/s, 1 Mibit/s = 1,048,576 bit/s (powers of 2).
ISPs always advertise speeds in SI decimal Mbit/s. Divide by 8 to convert Mbit/s to MB/s.
The dropdowns below group units by standard.

Common Data Transfer Rate Conversions
- 1 B/s = 8 bit/s
- 1 kbit/s = 1,000 bit/s (SI) | 1 Kibit/s = 1,024 bit/s (IEC)
- 1 Mbit/s = 1,000,000 bit/s | divide by 8 to get MB/s (125 KB/s per Mbit/s)
- 1 Gbit/s = 1,000,000,000 bit/s | 1 Gbit/s = 125 MB/s
- 1 Tbit/s = 1012 bit/s | 1 Tbit/s = 125 GB/s
- 100 Mbit/s (typical home broadband) ≈ 12.5 MB/s download speed
- 1 Gbit/s Ethernet = 125 MB/s effective throughput
- SI prefixes (kbit/s, Mbit/s, Gbit/s ...) use powers of 10 - used in networking and ISP specs
- IEC prefixes (Kibit/s, Mibit/s, Gibit/s ...) use powers of 2 - used in some hardware engineering contexts
