Why your 1 TB hard drive shows only 931 GB in Windows

Hard drive manufacturers use the decimal (SI) standard where 1 kilobyte = 1,000 bytes, 1 megabyte = 1,000,000 bytes, and 1 terabyte = 1,000,000,000,000 bytes. Operating systems (Windows, macOS, Linux) use the binary (IEC) standard where 1 kibibyte = 1,024 bytes. A drive advertised as 1 TB therefore contains 1,000,000,000,000 bytes ÷ 1,024⁴ = 0.909 TiB, which Windows displays as approximately 931 GB. This discrepancy is not fraud — it is a standards mismatch that has confused consumers since the 1990s. Our converter supports both standards and clearly labels which is which.

Real-world file size reference points

To put sizes in perspective: a typical WhatsApp text message is ~1 KB; a high-quality JPEG photo is 2–5 MB; a 3-minute MP3 song is ~3–5 MB; a 4K movie is 50–100 GB; the entire English Wikipedia (text only) is ~21 GB; the human genome is ~1.5 GB of data. Understanding these anchors helps when planning cloud storage, estimating backup costs or optimising web assets. Pair with our Image Compressor to reduce digital asset sizes before storage or upload.
