How to Calculate & Formula Details

Mathematical Model FormulaDecimal: 1 KB = 1,000 bytes. Binary: 1 KiB = 1,024 bytes.

A data storage converter translates file sizes and storage capacities between bytes, kilobytes, megabytes, gigabytes, and terabytes — useful for understanding hard drive specs, file sizes, and cloud storage plans.

Binary vs. Decimal Standards

Storage manufacturers typically use decimal (base-1000) units, where 1 KB = 1,000 bytes. Operating systems often use binary (base-1024) units, where 1 KiB = 1,024 bytes. This discrepancy is why a "1TB" drive shows less capacity in Windows.

Common Conversions (Decimal)

1 KB = 1,000 bytes
1 MB = 1,000,000 bytes
1 GB = 1,000,000,000 bytes

Frequently Asked Questions

Why does my 1TB drive show less than 1,000GB in Windows?

Windows uses binary (base-1024) calculations while drive manufacturers use decimal (base-1000), so a 1,000,000,000,000-byte "1TB" drive shows as roughly 931 GiB in the OS.

How many MB are in a GB?

Using decimal standard, 1 GB equals 1,000 MB. Using binary standard, 1 GiB equals 1,024 MiB.

What is the difference between a bit and a byte?

A byte consists of 8 bits. Data transfer speeds are often measured in bits (Mbps), while file sizes are measured in bytes (MB).
