Mbps to Gbps formula and what each symbol means
Gbit/s = Mbit/s × 0.001
| Symbol | Meaning |
|---|---|
| Mbit/s | Megabit per second |
| Gbit/s | Gigabit per second |
Mbps to Gbps examples
1 Mbit/s
1 Mbit/s × 0.001 = 0.001 Gbit/s.
10 Mbit/s
10 Mbit/s × 0.001 = 0.01 Gbit/s.
100 Mbit/s
100 Mbit/s × 0.001 = 0.1 Gbit/s.
Mbps compared with Gbps
One Gbit/s is 1,000 times as large as one Mbit/s, so your number gets smaller when you convert mbps to gbps and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About mbps and gbps
Megabit per second (Mbit/s): One million bits per second. Gigabit per second (Gbit/s): One billion bits per second.
Where mbps to gbps conversions are used
Storage interfaces such as SATA, NVMe and USB list rates in MB/s or Gbps. Internet plans are sold in megabits per second, while downloads display megabytes per second.
How to calculate Mbps to Gbps step by step
- Enter the value in Mbit/s (the starting unit).
- Multiply by 0.001, because 1 Mbit/s = 0.001 Gbit/s.
- The product is the value in Gbit/s. To go back, divide by 0.001 or multiply by 1,000.

Common mistakes when calculating Mbps to Gbps
- Mixing decimal (MB/s) and binary (MiB/s) units.
- Dividing when you should multiply: from Mbit/s to Gbit/s multiply by 0.001; from Gbit/s to Mbit/s divide by 0.001.
Mbps to Gbps FAQ
How many Gbit/s are in 1 Mbit/s?
1 Mbit/s equals 0.001 Gbit/s.
How many Mbit/s are in 1 Gbit/s?
1 Gbit/s equals 1,000 Mbit/s.
Is 1 Mbit/s = 0.001 Gbit/s an exact conversion?
Yes. The megabit per second and the gigabit per second are both defined exactly in SI terms, so the ratio has no measurement uncertainty; 0.001 is just that ratio shown to 7 significant figures.
What is a gigabit per second (Gbit/s)?
One billion bits per second.
How can I estimate mbps to gbps in my head?
One Gbit/s is 1,000 times as large as one Mbit/s, so your number gets smaller when you convert mbps to gbps and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
What is 25 Mbit/s in gbps?
25 Mbit/s = 0.025 Gbit/s (since 25 × 0.001).
What is 80 Mbit/s in gbps?
80 Mbit/s = 0.08 Gbit/s (since 80 × 0.001).
What is 500 Mbit/s in gbps?
500 Mbit/s = 0.5 Gbit/s (since 500 × 0.001).
How many decimals should I keep when converting Mbit/s to Gbit/s?
Match the precision of your original measurement. For example, 0.01 Gbit/s rounds to 0.01 Gbit/s at 3 significant figures; keep more digits only for engineering or scientific work.
