How the Data Storage Converter works
Each value is converted to a base unit using exact, internationally defined factors, then to the unit you want.
Decimal: 1 KB = 1,000 bytes, 1 GB = 10⁹ bytes · Binary: 1 KiB = 1,024 bytes, 1 GiB = 2³⁰ bytes · 1 byte = 8 bits
Step-by-step calculation
- 1Enter the value.
- 2Choose the unit you have and the unit you want.
- 3The value is converted to a base unit with exact factors.
- 4It is converted to your target unit (all others are listed too).
Worked example
A "1 TB" drive holds 10¹² bytes, which Windows shows as about 931.32 GiB ("GB" in Windows).

Why use a Data Storage Converter?
Understand drive sizes, downloads and memory.
Important factors that can affect your results
- Decimal (KB) vs binary (KiB) units.
- Bits vs bytes for internet speeds.
- Formatted capacity is smaller.
Frequently asked questions
Why does my new drive look smaller?
Drive makers use decimal units (1 TB = 10¹² bytes) while Windows reports binary units (GiB) but labels them GB.
Bits or bytes for internet speed?
Internet speeds use bits: 100 Mbps is about 12.5 MB per second.
