Common mistakes
- Wrong direction
Multiplying when you should divide (or vice versa) flips the result. Double-check which unit is the source and which is the target.
- Aggressive rounding
Rounding too early in a multi-step calculation amplifies the error. Keep extra decimals until the final step.
When precision matters
