Network speed converter

Convert between Mbps, Gbps, MB/s, GB/s — and see exactly how fast your interface actually moves data.

Bits vs bytes: Network speeds are always quoted in bits (Mbps), but file transfers display in bytes (MB/s). Divide Mbps by 8 to get MB/s — a 100 Mbps connection transfers at ~12.5 MB/s. Storage interfaces (SATA, NVMe) are typically quoted in bytes per second.

Maxing out your switch? Multi-gig managed switches (2.5G, 10G) are now accessible at every budget level. Mikrotik and Netgear both have solid options that support VLAN trunking and link aggregation. Browse multi-gig switches →
