About these units
Quart (US) (qt (US))
A US quart equals 32 US fluid ounces or 946 milliliters, exactly 1/4 of a US gallon. It is commonly used for milk, juice, motor oil, and household chemicals. The quart's convenient scale makes it ideal for medium-sized liquid quantities—larger than a pint but smaller than a gallon. It remains widely used in American kitchens, automotive maintenance, and everyday shopping. Like other US customary units, the quart persists because consumers and industries have longstanding infrastructures built around it.
Deciliter (dL)
A deciliter, 1/10 of a liter, appears prominently in medical diagnostics—especially in blood testing. Many laboratory measurements use dL as the denominator, such as mg/dL for blood glucose or cholesterol levels. In Europe, food packaging sometimes lists nutritional values per deciliter, especially for dairy products and soups. The dL is just large enough to be meaningful while still small enough for dietary and medical precision. Though not as common as liters or milliliters, the deciliter serves specialized roles where moderate scale and medical tradition intersect.
