Convert internet and transfer speeds between bits per second and bytes per second: kbps, Mbps, Gbps, kB/s, MB/s, MiB/s and more.
| Conversion | Result | Formula |
|---|---|---|
| Megabits per second to megabytes per second | 1 Mbps = 0.125 MB/s | megabytes per second = megabits per second ÷ 8 |
| Megabytes per second to megabits per second | 1 MB/s = 8 Mbps | megabits per second = megabytes per second × 8 |
| Gigabits per second to megabits per second | 1 Gbps = 1,000 Mbps | megabits per second = gigabits per second × 1,000 |
| Megabits per second to gigabits per second | 1 Mbps = 0.001 Gbps | gigabits per second = megabits per second ÷ 1,000 |
| Kilobits per second to megabits per second | 1 kbps = 0.001 Mbps | megabits per second = kilobits per second ÷ 1,000 |
| Megabits per second to kilobits per second | 1 Mbps = 1,000 kbps | kilobits per second = megabits per second × 1,000 |
| Megabits per second to kilobytes per second | 1 Mbps = 125 kB/s | kilobytes per second = megabits per second × 125 |
| Kilobytes per second to megabits per second | 1 kB/s = 0.008 Mbps | megabits per second = kilobytes per second ÷ 125 |
| Gigabits per second to megabytes per second | 1 Gbps = 125 MB/s | megabytes per second = gigabits per second × 125 |
| Megabytes per second to gigabits per second | 1 MB/s = 0.008 Gbps | gigabits per second = megabytes per second ÷ 125 |
| Unit | Symbol | Equal to |
|---|---|---|
| Bit per second | bit/s | 1 bit/s |
| Kilobit per second | kbps | 1,000 bit/s |
| Megabit per second | Mbps | 1,000,000 bit/s |
| Gigabit per second | Gbps | 1,000,000,000 bit/s |
| Terabit per second | Tbps | 1,000,000,000,000 bit/s |
| Byte per second | B/s | 8 bit/s |
| Kilobyte per second | kB/s | 8,000 bit/s |
| Megabyte per second | MB/s | 8,000,000 bit/s |
| Gigabyte per second | GB/s | 8,000,000,000 bit/s |
| Kibibyte per second | KiB/s | 8,192 bit/s |
| Mebibyte per second | MiB/s | 8,388,608 bit/s |
| Gibibyte per second | GiB/s | 8,589,934,592 bit/s |
Internet providers advertise speeds in megabits per second (Mbps), but browsers and download managers show megabytes per second (MB/s). Because a byte is 8 bits, divide Mbps by 8 to get MB/s.
| Connection | MB/s | Time to download 1 GB |
|---|---|---|
| 10 Mbps | 1.25 | about 13 min 20 s |
| 50 Mbps | 6.25 | about 2 min 40 s |
| 100 Mbps | 12.5 | about 1 min 20 s |
| 1 Gbps | 125 | about 8 s |
Real download speeds are usually a little lower than the advertised rate because of network overhead and server limits.
Divide by 8. For example, 100 Mbps equals 12.5 MB/s.
One gigabit per second is 1,000 megabits per second.
Plans are quoted in megabits per second, while downloads show megabytes per second, which is 8 times smaller. Overhead and server speed also reduce the rate.
