Gbps to Mbps formula and what each symbol means
Mbit/s = Gbit/s × 1,000
| Symbol | Meaning |
|---|---|
| Gbit/s | Gigabit per second |
| Mbit/s | Megabit per second |
Gbps to Mbps examples
1 Gbit/s
1 Gbit/s × 1,000 = 1,000 Mbit/s.
10 Gbit/s
10 Gbit/s × 1,000 = 10,000 Mbit/s.
100 Gbit/s
100 Gbit/s × 1,000 = 100,000 Mbit/s.
Gbps compared with Mbps
One Gbit/s is 1,000 times as large as one Mbit/s, so your number gets bigger when you convert gbps to mbps and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About gbps and mbps
Gigabit per second (Gbit/s): One billion bits per second. Megabit per second (Mbit/s): One million bits per second.
Where gbps to mbps 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 Gbps to Mbps step by step
- Enter the value in Gbit/s (the starting unit).
- Multiply by 1,000, because 1 Gbit/s = 1,000 Mbit/s.
- The product is the value in Mbit/s. To go back, divide by 1,000 or multiply by 0.001.

Common mistakes when calculating Gbps to Mbps
- Mixing decimal (MB/s) and binary (MiB/s) units.
- Dividing when you should multiply: from Gbit/s to Mbit/s multiply by 1,000; from Mbit/s to Gbit/s divide by 1,000.
Gbps to Mbps FAQ
How many Mbit/s are in 1 Gbit/s?
1 Gbit/s equals 1,000 Mbit/s.
How many Gbit/s are in 1 Mbit/s?
1 Mbit/s equals 0.001 Gbit/s.
Is 1 Gbit/s = 1,000 Mbit/s an exact conversion?
Yes. The gigabit per second and the megabit per second are both defined exactly in SI terms, so the ratio has no measurement uncertainty; 1,000 is just that ratio shown to 7 significant figures.
What is a megabit per second (Mbit/s)?
One million bits per second.
How can I estimate gbps to mbps in my head?
One Gbit/s is 1,000 times as large as one Mbit/s, so your number gets bigger when you convert gbps to mbps and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
What is 40 Gbit/s in mbps?
40 Gbit/s = 40,000 Mbit/s (since 40 × 1,000).
What is 200 Gbit/s in mbps?
200 Gbit/s = 200,000 Mbit/s (since 200 × 1,000).
What is 3 Gbit/s in mbps?
3 Gbit/s = 3,000 Mbit/s (since 3 × 1,000).
How many decimals should I keep when converting Gbit/s to Mbit/s?
Match the precision of your original measurement. For example, 10,000 Mbit/s rounds to 10,000 Mbit/s at 3 significant figures; keep more digits only for engineering or scientific work.
