Binary to Decimal Converter

About This Tool

So, you’ve got a string of 1s and 0s and no idea what it means in regular numbers? Yeah, been there. Binary to decimal conversion doesn’t have to be some mysterious computer science ritual. This tool just takes that binary number—like 1010 or 110110—and turns it into the decimal number you actually recognize, like 10 or 54. It’s not magic. It’s math. But instead of making you do the math yourself (because who’s got time for that?), this converter does it in a split second. Whether you’re debugging code, learning how computers think, or just curious about how 1111 becomes 15, this thing’s got your back.

Key Features

• Fast conversion—paste your binary, hit convert, done.
• Handles any length binary number, as long as it’s valid (so no letters or symbols).
• Works right in your browser—no downloads, no sign-ups, no nonsense.
• Shows a quick breakdown if you want to see how the math works (optional, but helpful for learning).
• Mobile-friendly. Yeah, it works on your phone too.

FAQ

What’s the longest binary number this can handle?
As long as your browser doesn’t crash, it’ll take it. Realistically, you’re probably not pasting in a million digits, so you’re fine. Most people use it for 8-bit, 16-bit, or 32-bit numbers—like 11000011 or 1010101010101010. Those convert without a hitch.

Why would I even need this?
Good question. Maybe you’re working with low-level code, configuring hardware, or just stuck on a homework problem. Binary shows up in networking, electronics, and programming all the time. This tool saves you from manually calculating powers of two like it’s 1985.
