Why does a 1 TB hard drive show only 931 GB on Windows?
Drive manufacturers measure 1 TB as 1,000,000,000,000 Bytes (decimal), whereas Windows measures in binary gibibytes (1 TiB = 1024^4 bytes = 931.32 GiB).

Data Storage Converter - Bytes, KB, MB & GB | 1ClickTools
Convert digital data storage units between Bytes, KB, MB, GB, TB, and PB. Binary (1024) and Decimal (1000) standards 100% in browser.
About This Tool
Understanding data storage units is fundamental when sizing hard drives, managing cloud storage subscriptions, optimizing server bandwidth, and calculating file download times. However, confusion often arises due to differing standards: commercial drive manufacturers use Decimal prefixes (1 KB = 1000 Bytes), whereas operating systems like Windows use Binary IEC prefixes (1 KiB = 1024 Bytes). Our browser-native Data Storage Converter allows you to convert any value across the entire digital spectrum instantly. You can toggle between Binary SI standards (base-2: 1024) and Decimal SI standards (base-10: 1000), viewing simultaneous conversions across Bytes, KB, MB, GB, TB, PB, and EB. Because calculation algorithms run 100% locally within client-side browser RAM using native JavaScript arithmetic, inputs execute in under a millisecond with complete privacy.
Frequently Asked Questions
Is my numeric data saved on any web server?
No. 1ClickTools calculates conversions 100% locally in your browser memory.
What is the difference between MB and MiB?
MB (Megabyte) uses base-10 decimal (1,000,000 bytes). MiB (Mebibyte) uses base-2 binary (1,048,576 bytes).
How many Megabytes are in a Gigabyte?
In binary OS calculations, 1 GB = 1,024 MB. In decimal storage standards, 1 GB = 1,000 MB.
