Does the conversion factor change for different types of miles or kilometers?
No, the standard international mile and kilometer have fixed lengths. However, some older or regional miles (like the nautical mile) are different, but those are not relevant for simple km to miles conversions.
Is rounding during conversion acceptable for practical use?
Yes, rounding results to 3-4 decimal places is sufficient for most uses such as travel or running distances. Extreme precision is rarely necessary outside scientific contexts.
Why might some calculators give slightly different results?
Differences come from rounding or truncating decimals at different steps. Also, some devices might use fewer decimal places in the conversion factor, causing small variances.
