How to Convert Megabits Per Second to Gigabytes Per Second
To convert megabits per second to gigabytes per second, divide by 8,000 (or multiply by 0.000125). This conversion accounts for the 8:1 relationship between bits and bytes—network speeds are measured in bits, while file sizes use bytes. Use our how many Mbps in Gigabytes Per Second.
Mbps is a bit-based bandwidth commonly used for Home internet speeds, WiFi connections, streaming video quality. When you see your ISP advertise speeds in Mbps, this is the raw network bandwidth. You might also need: how many Kilobits Per Second in a Mbps.
GB/s is what you actually experience when downloading files. Your browser, torrent client, or download manager shows speeds in GB/s because that's how fast data is being written to your storage. Related: calculate TiB/s to GB/s.
1 Mbps = 0.000125 GB/s — or equivalently, 1 GB/s = 8,000Mbps.
Mbps to GB/s Conversion Formula
// Convert Mbps to GB/s
GB/s = Mbps × 0.000125
// Reverse: Convert GB/s to Mbps
Mbps = GB/s × 8,000
Mbps to GB/s Conversion Examples
10 Mbps = 0.00125 GB/s
50 Mbps = 0.00625 GB/s
100 Mbps = 0.0125 GB/s
500 Mbps = 0.0625 GB/s
1,000 Mbps = 0.125 GB/s
What Is Megabit Per Second (Mbps)?
A megabit per second is 1,000,000 bits per second. The standard unit for home internet speeds. Use our B/s to Eibps conversion rate.
The megabit per second is a bit-based bandwidth unit measuring data transfer speed, network bandwidth, or throughput capacity. You might also need: converting Gigabytes to Kibibytes.
Common uses: Home internet speeds, WiFi connections, streaming video quality Use our Megabits Per Second in Yobibits Per Second.
1 Mbps = 1 × 10⁶ bits per second.
The megabit per second can be abbreviated as Mbps; for example, 1 megabit per second can be written as 1 Mbps.
What Is Gigabyte Per Second (GB/s)?
A gigabyte per second is 1,000 megabytes per second. Used for NVMe SSDs and high-speed storage. Related: bps to GB/s.
The gigabyte per second is a byte-based throughput unit measuring data transfer speed, network bandwidth, or throughput capacity. Learn more: KiB/s to Ebps converter.
Common uses: NVMe SSD speeds, PCIe bandwidth, high-performance computing, GPU memory You might also need: Kib to b calculator.
1 GB/s = 8 × 10⁹ bits per second.
The gigabyte per second can be abbreviated as GB/s; for example, 1 gigabyte per second can be written as 1 GB/s.

Bits vs Bytes: Understanding Network Speed vs Download Speed
The difference between bits and bytes is crucial when working with megabits per second and gigabytes per second:
| Unit Type | Symbol | Used For |
|---|---|---|
| Bits per second | Mbps, Gbps | ISP speeds, network bandwidth, WiFi specs |
| Bytes per second | MB/s, GB/s | Download managers, file transfers, SSD speeds |
Quick Conversion Rule
Divide bits by 8 to get bytes. Your "100 Mbps" internet connection delivers a maximum of 12.5 MB/s actual download speed.
Real-world speeds are typically 70-85% of theoretical maximum due to protocol overhead, network congestion, and other factors.
💡 Storage Engineer Tip
Divide bits by 8 to get bytes. When your ISP advertises "100 Mbps," your maximum download speed is 12.5 MB/s. Real-world speeds are typically 70-85% of theoretical maximum due to protocol overhead.
