Mistakes to avoid with data conversions
- Megabits vs megabytes: your '100 Mbps' connection downloads at ~12.5 MB/s — ISPs quote bits, files are bytes.
- Decimal vs binary units: drives are sold in decimal GB (10⁹), so a '1 TB' drive shows ~931 'GB' (GiB) in Windows.
- Assuming video size scales with length only — resolution and bitrate matter more than minutes.
