How power conversion works
Each power conversion is performed by first expressing the input in a single base unit (Watts) 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.
