Where This Comes Up
Quarts are how Americans buy milk, stock, motor oil and ice cream. Metric equivalents are sold in liters, and the two are close enough that the difference is easy to miss.
A quart of motor oil is 946.353 milliliters, so a 5-quart oil change needs 4.73 liters — a 5-liter jug leaves some over.
What People Get Wrong
A quart is not a liter. Buying a 1-liter carton to replace a quart of stock gives 5.7 percent more, which is enough to thin a sauce noticeably.
