How it's calculated & sources
The Bitrate Converter uses the standard, deterministic formula, so the same inputs always produce the same result. It runs entirely in your browser, so your inputs are never uploaded. Last reviewed June 2026.

Free & no sign-up · runs entirely in your browser. Results are estimates for general information, not professional advice — verify important decisions with a qualified expert. Last reviewed June 2026.

How it works

1 byte = 8 bits. ISP speeds are usually quoted in Mbit/s; downloads in MB/s.

Example

100 Mbit/s = 12.5 MB/s.

Frequently asked questions

Quick answers

Short, sourced answers to the questions people (and AI assistants) ask most.

What is Bitrate?
A bitrate converter changes a data rate between bits and bytes per second and their multiples (kbps, Mbps, Gbps, MB/s).
Why does Bitrate matter?
The same data rate in your target unit; divide bits by 8 to get bytes.
How is Bitrate calculated?
It converts through bits per second, using 8 bits per byte, and lets you switch between decimal (1,000) and binary (1,024) multiples. Formula: 1 byte = 8 bits; 1 kbps = 1,000 bps; 1 Mbps = 1,000 kbps; download MB/s = Mbps / 8.
What are common bitrate mistakes?
Confusing megabits (Mbps, network) with megabytes (MB/s, files) - a factor of 8.
When should you use the Bitrate Converter?
Use it to work out download times, compare internet plans (Mbps) with file sizes (MB), or set a media bitrate.

How the Bitrate Converter works

1 byte = 8 bits; 1 kbps = 1,000 bps; 1 Mbps = 1,000 kbps; download MB/s = Mbps / 8

Bitrate — bits per second vs bytes per second (decimal)

1 Mbit/s1,000,0001250.125
1 Gbit/s1,000,000,000125000125

Common mistakes to avoid

  • Confusing megabits (Mbps, network) with megabytes (MB/s, files) - a factor of 8.
  • Mixing decimal (1,000) and binary (1,024) prefixes.
  • Forgetting overhead makes real speeds lower than the rated bitrate.

I built a free pregnancy due date calculator that works instantly in the browser — no signup, no ads in your face
Body
Hey r/[subreddit],

I kept needing a quick pregnancy due date calculator and most options online were slow or behind paywalls, so I built one that:

• Runs 100% in your browser (your data never leaves your device)
• No signup, no email wall, no popups
• Loads in under a second on mobile

It covers the standard pregnancy due date use cases (pregnancy, due, date, baby) and links out to the formula + worked examples if you want to learn the math.
