Bandwidth Converter

Convert digital transfer rates between bits-per-second and bytes-per-second units from bps through Tbps and TB/s, with line-rate equivalents shown at once.

Digital transfer

Convert bandwidth between bit-rate and byte-rate units without losing the 8-to-1 relationship

Compare ISP line rates, storage throughput, and download speeds cleanly across bits per second and bytes per second units from bps through Tbps and TB/s.

Scope note

This page converts line-rate units only. It does not estimate transfer time, account for protocol overhead, or switch between decimal networking labels and binary storage labels.

Quick checkpoints

1 byte per second equals 8 bits per second. A 100 Mbps connection is 12.5 MB/s at line rate, and 1 Gbps is 125 MB/s before protocol overhead.

Bandwidth converter: Mbps, MB/s, Gbps, and TB/s explained

A bandwidth converter lets you compare the same transfer rate in both bit-based and byte-based units. That matters because broadband plans, network equipment, and media bitrates are usually expressed in bits per second, while file managers, storage tools, and copy dialogs often use bytes per second. This page keeps those labels aligned so you can compare line rates cleanly.

Why bandwidth labels cause confusion

The most common mismatch is simple but costly: network speeds are usually advertised in bits per second, while file-transfer tools often display bytes per second. Because one byte equals eight bits, a line advertised at 100 Mbps is only 12.5 MB/s before any protocol overhead is applied.

That is why a user can buy a fast connection and still feel that the transfer window is showing a smaller number than expected. The two readings may both be correct; they are just expressed in different unit families.

1 B/s = 8 bps

A byte-based rate is eight times the matching bit-based rate.

100 Mbps = 12.5 MB/s

How this converter works

The calculator converts the source value into bits per second first, then derives every supported output from that shared line-rate base. That keeps the numbers internally consistent even when you move between very small units such as bps and very large units such as Tbps or TB/s.

The converter uses decimal transfer prefixes, which is the normal convention for networking throughput. It does not switch into binary storage prefixes such as MiB or GiB because those belong to file-size and storage-capacity discussions rather than transfer-rate naming.

When to use a bandwidth converter

Use it when comparing ISP plans, translating switch-port speeds into approximate file-transfer throughput, checking media bitrates, or reconciling performance dashboards that use different labels. It is also useful when a download tool shows MB/s but your service provider advertises Mbps or Gbps.

Use a download-time calculator instead when you want to estimate how long a transfer will take. Bandwidth conversion alone translates the rate label; it does not include file size, latency, retransmissions, or throughput loss from real networks.

Frequently asked questions

Why is 100 Mbps not the same as 100 MB/s?

Because Mbps means megabits per second while MB/s means megabytes per second. Since one byte contains eight bits, 100 Mbps equals 12.5 MB/s at line rate.

Does this converter show real download speed?

It shows the unit-equivalent line rate only. Real throughput can be lower because of Wi-Fi quality, server throttling, congestion, protocol overhead, and storage write limits.

Why are binary units like MiB/s not included here?

This page focuses on transfer-rate naming, which is usually expressed with decimal prefixes in networking contexts. Binary prefixes are more relevant for storage-capacity and file-size discussions.
