Data Size Converter

Developer

Convert data sizes between B, KB, MB, GB and TB with decimal (1000) or binary (1024) base. See every unit at once. Free and instant.

Decimal base matches drive capacities; binary base matches how many operating systems count memory and files.

What is the difference between 1000 and 1024?

Decimal base uses 1 KB = 1000 bytes, which storage manufacturers use. Binary base uses 1 KiB = 1024 bytes, which operating systems often use. Choose the base that matches your situation.

Which base should I use?

  • Decimal (1000) for drive capacity and data plans.
  • Binary (1024) for RAM, memory and file sizes shown by many systems.

Why see every unit at once?

Seeing one size in all units at the same time makes comparisons easy, whether you are checking upload limits, disk usage or email attachment caps.

Can I convert between bytes and TB?

Yes. Every unit from byte to terabyte is listed in one table, and you can enter a value in any of them to see the rest.

Is my data private?

Completely. The conversion is simple multiplication in your browser — nothing is calculated on a server or stored anywhere.
