Online Data Transfer Converter

Convert Mbps, Gbps, MB/s, and KB/s. Calculate your connection's real download speed.

Transfer speed measures bits or bytes per second. ISPs advertise in Mbps (megabits): since 1 byte = 8 bits, 100 Mbps equals 12.5 MB/s of real download. To know your download in MB/s, divide the Mbps by 8. Reference speeds: HDD ≈ 80–160 MB/s; SATA SSD ≈ 500–600 MB/s; NVMe SSD ≈ 3,000–7,000 MB/s; Gigabit network = 1 Gbps = 125 MB/s; USB 3.0 = 5 Gbps; USB 4.0 = 40 Gbps. This converter covers bps, Kbps, Mbps, Gbps, and their bytes/second equivalents.

Frequently Asked Questions

What is the difference between Mbps and MB/s?

Mbps = megabits/s; MB/s = megabytes/s. Since 1 byte = 8 bits, 100 Mbps ÷ 8 = 12.5 MB/s.

My internet is 100 Mbps. How much do I download per second?

100 Mbps ÷ 8 = 12.5 MB/s maximum theoretical speed.

How many Mbps are in 1 Gbps?

1 Gbps = 1,000 Mbps.

What is the speed of a Gigabit network?

1 Gbps = 125 MB/s maximum theoretical rate.
