Data Transfer Rate Conversion: Mbps, MB/s, Gbps and KiB/s

Published on July 30, 2026

Data Transfer Rate Conversion: Mbps, MB/s, Gbps and KiB/s

Fast reference

TL;DR

To convert Mbps to MB/s, divide by 8. To convert Gbps to Mbps, multiply by 1000. Be careful with binary units such as KiB/s because they use powers of 1024.

Guide

Overview

A clear guide to converting Mbps, MB/s, Gbps and KiB/s without mixing bits, bytes, decimal prefixes and binary prefixes.

Use decimal prefixes for common internet speed labels unless the unit explicitly uses binary notation such as KiB or MiB.

  • Use the chart for fast checks.
  • Use the linked calculator for custom values.
  • Keep the unit definition clear before rounding.
  • Record the source when values enter technical work.

Workflow

How to use this reference

Use the unit spelling as the clue. Lowercase b means bit; uppercase B means byte.

Step 1

Convert bits to bytes by dividing by 8.

Step 2

Convert bytes to bits by multiplying by 8.

Step 3

Treat Mbps and Gbps as decimal network units.

Step 4

Treat KiB, MiB and GiB as binary units.

Quality check

Common mistakes to avoid

Small capitalization errors can create an eight-times mistake.

Do not read MB/s as Mbps.
Do not mix MiB/s with MB/s in storage benchmarks.
Do not estimate download time without accounting for protocol overhead.

FAQ

Common questions

Is Mbps faster than MB/s?

They measure related rates. 8 Mbps equals 1 MB/s before overhead.

Why do downloads look slower than internet speed?

Internet plans are usually sold in bits per second, while browsers often show bytes per second.

What does KiB/s mean?

KiB/s means kibibytes per second, using 1024 bytes per KiB.
