Common mistakes to avoid
- Mixing US vs UK systems - gallon, pint, and stone differ between US and UK. Always check your source system before converting.
- Rounding too early - keep the full factor (like 6.35029, not 6.35) until the final display, then round to 2 decimals for daily use.
- Using 1000 instead of 1024 for digital storage - RAM and files use 1024 (binary), drive makers use 1000 (decimal). Use 1024 for exact.
Always double-check your source system and use the exact factor from BIPM or NIST for critical work.
