Understanding Units and Conversions

Unit conversions are reliable only when the source and target units describe the same quantity.

Unit conversions are reliable only when the source and target units describe the same quantity. Check whether a conversion uses a fixed factor or an offset, as temperature conversions do. Keep the direction explicit, avoid mixing US customary and imperial units, and convert back to the starting unit as a sanity check.

A practical checklist

1. Define the task and the result you need.
2. Check units, definitions, assumptions, and limitations.
3. Test a small example and compare it with a trusted reference.
4. Keep notes of the method when results will be shared or used for decisions.
