Why Does a 1 TB Hard Drive Show as 931 GB in Windows?
Storage makers rate 1 TB as 1,000,000,000,000 Bytes (base 1000). Windows calculates capacities using base 1024 (1,000,000,000,000 ÷ 1024³ = 931.32 GiB), producing the apparent discrepancy without any actual lost capacity.
Overview
Free digital data and file storage converter. Switch between 1000-based decimal (hard drive manufacturers) and 1024-based binary (Windows/OS RAM) standards, calculate file download durations across broadband speeds, and understand disk capacity discrepancies.
Digital Storage & Data Converter Complete Guide
Understanding digital storage units—Bits, Bytes, KB, MB, GB, TB, and PB—is essential for managing files, server hosting, and bandwidth.
Storage manufacturers use base 1000 (1 TB = 1,000,000,000,000 Bytes), whereas operating systems like Windows calculate using base 1024 (GiB), explaining why a 1 TB SSD reads as 931 GB.
Our tool toggles between both standards and calculates file download durations across standard network speeds.

Frequently Asked Questions
2 Q&AsHow many MB are in 1 GB?
In binary computing (Windows), 1 GB = 1,024 MB. In decimal metric standards, 1 GB = 1,000 MB.
What is the difference between a Bit and a Byte?
1 Byte (B) equals 8 Bits (b). Network bandwidth is rated in bits (e.g. 100 Mbps), while file sizes use Bytes (MB/GB).
