Common mistakes and definitions

Pressure is often reported as absolute or gauge. Make sure your source values use the same reference before converting (especially in HVAC and engineering specs).

Confusing absolute pressure with gauge pressure.
Dropping prefixes (Pa vs kPa vs MPa) while comparing values.
Rounding too early before converting between small units.
