Five common mistakes
- Mixing units — entering height in centimeters but weight in pounds. Unit Converter can't tell, and gives a confidently wrong answer.
- Forgetting decimals — typing "170" when you mean "1.70m". One extra digit changes everything.
- Rounding inputs too aggressively — small inputs to a sensitive formula amplify error.
- Trusting the output absolutely — a calculation from Unit Converter is a data point. Real decisions need more context.
- Using the wrong formula entirely — there's a closely related formula for almost every calc. Check that Unit Converter is the one you actually need.
