How the Unit Converter works

One liter is 1.056688209 US quarts. Both units are defined against the same SI base unit, so the factor is derived from two exact definitions rather than measured. It is exact in principle and does not land on a round number.

Worked through: 2 L x 1.05668821 = 2.11338 qt.

Going the other way, one US quart is 0.946352946 liters.

For mental arithmetic: Add about 6%.

A liter is 1.05669 US quarts, so a liter and a quart are within 6% of each other. That is close enough for recipes and drink sizes to swap them without comment, and far enough that a fuel or chemical measurement should not. The imperial quart is a different size again at 1.1365 liters, so a liter is 0.88 imperial quarts. This is the pair where 'about the same' is true for a jug of milk and false for anything that is being billed.

Precision is worth matching to the input. A measurement given as 0.5 L carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
