How length conversion works
Each length conversion is performed by first expressing the input in a single base unit (Meters) and then scaling to the target unit. Factors are stored to full precision, so a value converted to another unit and back returns the original number. Results here match the formula, worked examples and reference table shown on every individual conversion page.
