Megabit/s to Gigabit/s (Megabit/s to Gigabit/s)
Result
0.001 Gigabit/s
Formula
Gigabit/s = Megabit/s × 0.001
1 Megabit/s = 0.001 Gigabit/s, and 1 Gigabit/s = 1,000 Megabit/s.
Storage here uses binary multiples (1 KB = 1,024 bytes, 1 MB = 1,024² bytes), the convention most operating systems use. The IEC names for these are kibibyte (KiB), mebibyte (MiB) and so on. Bandwidth uses decimal SI prefixes (1 Mbit/s = 1,000,000 bit/s).
Worked examples
- 1 Megabit/s × 0.001 = 0.001 Gigabit/s
- 10 Megabit/s × 0.001 = 0.01 Gigabit/s
- 100 Megabit/s × 0.001 = 0.1 Gigabit/s
Common mistakes
- Drive manufacturers use decimal units: a "1 TB" drive holds 10¹² bytes, which an operating system shows as about 931 GB (binary).
- Bits are not bytes: a 100 Mbit/s connection downloads at most 12.5 MB per second (divide by 8), before protocol overhead.

The units
- Megabit/s (Megabit/s)
- 1 Megabit/s = 1,000,000 Bit/s.
- Gigabit/s (Gigabit/s)
- 1 Gigabit/s = 1,000,000,000 Bit/s.
