Notes
How to use a conversion chart
A chart is best for quick checks and common numbers. If you are copying a measurement into a shipping label, a recipe, or a product listing, use a calculator and match the precision of the original measurement.
When a definition is exact (like inches and centimeters), the chart can be exact too. When a factor creates a long decimal (like kilometers to miles), rounding is normal.
