Input meaning and unit policy

Common conversions
Use centimeters or millimeters for small objects, meters for room and furniture dimensions, kilometers or miles for travel distance, and feet or yards when reading plans or sports-field measurements.
Common mistakes to avoid
Do not mix a rounded chart value with an exact conversion factor in the same calculation. If a source already rounded a value, keep that rounding visible in your notes before comparing it with another unit.
Interpretation guidance
The converter keeps exact factors internally and rounds displayed decimals for readability. For a chain of calculations, carry a few extra digits from the table and round only the final value.
