Common mistakes to avoid
- Dividing when you should multiply. Because 1 inch = 0.000016 miles, the answer should be smaller than the number you started with.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
For everyday measurements round to the nearest whole unit or to one decimal place. Machining, sewing and construction usually need at least two decimals — and it is worth measuring in the target unit directly when tolerance matters.
How these units are defined
- Inch (in): Exactly 25.4 millimeters; the base small unit of US customary and Imperial length. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
- Mile (mi): The statute mile: 5,280 feet or exactly 1,609.344 meters. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
