Common mistakes and definitions

Weight and mass are often used interchangeably in everyday language. For technical work, keep definitions and symbols consistent and round only at the end.

Rounding too early (convert first, then round at the end).
Mixing similar-looking symbols (for example, “m” vs “mm”, or “b” vs “B”).
Copying values without the unit symbol, which makes validation harder.
