A data-rate conversion — megabits per second to gigabits per second — commonly needed when comparing internet or network speed specifications.
How it works
Dividing Mbps by 1,000 gives Gbps; multiplying Gbps by 1,000 gives Mbps back. Type into either field and the other updates instantly.
What this does not include
This does not include data size (bytes) conversions — for those, use this site’s MB-to-GB or KB-to-MB calculators instead. This tool is specifically for data rate (bits per second), not data size.
How to use this calculator
- Enter a value in either Mbps or Gbps — the other field fills in automatically.
Frequently asked questions
What’s the difference between data rate and data size?
Data rate (Mbps, Gbps) measures how fast data transfers per second; data size (MB, GB) measures a fixed amount of stored data — different quantities entirely, despite similar-looking abbreviations.
Where is this conversion most commonly needed?
Comparing internet service plan speeds, network equipment specifications, and data center connection capacities.
Why lowercase “b” for bits versus uppercase “B” for bytes?
It’s the standard convention distinguishing bits (lowercase b, as in Mbps) from bytes (uppercase B, as in MBps) — 8 bits make one byte.
