- Getting the unit wrong: the classic mix-up. Check the unit marker next to the first field before you calculate, and the tool will agree with you every time.
- Leaving a field empty: blank required fields mean no result — by design. The tool prompts you, you fill it in, done.
- Rushing the result: give the result a once-over before relying on it. The calculation is reliable; the only moving part is the number you typed.
- Remembering an old formula: the formula you remember may not fit this calculation's assumptions. The page shows the exact method, so rely on that.
- Entering values that do not fit the question: a strange answer is often a wrong input wearing a disguise. Re-read the fields and confirm the values match the question.
