Factors are entered by hand from NIST Handbook 130 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: US quarts to millilitres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
