Common mistakes

• ✕Applying the conversion factor in the wrong direction (GB → TB vs TB → GB).
• ✕Rounding intermediate steps — always convert once from the exact factor to keep full precision.
• ✕Why a 1 TB drive shows as 931 GB. The manufacturer sells 1 000 000 000 000 bytes (SI terabyte). Windows divides by 1024 three times and calls the result GB, giving 931.32. No storage is missing — the two systems simply label the same bytes differently. macOS and Linux now report in SI units, so the same drive shows as 1 TB there.
