Avoid unit-conversion mistakes
Practical example
Converting 1 kilometre gives 1,000 metres, but converting square or cubic units requires a different factor. Temperature also uses an offset rather than simple multiplication.
Interpreting the result
Select the physical quantity first, then the source and destination units. Preserve enough decimal places for the decision you are making and label the result when copying it.
Limits and common mistakes
Rounded display values may be unsuitable for engineering, laboratory or regulated work. Confirm critical conversions with the standard and precision required by your field.
