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.
Cubic Decimeter (dm³)
A cubic decimeter is defined as 1 liter, since it is the volume of a cube 10 centimeters per side. Though equivalent to the liter, dm³ is often used in engineering and physics because it fits neatly into the SI geometric framework. This unit is convenient when working with densities (kg/dm³), where the equivalence of 1 dm³ and 1 L simplifies many calculations involving fluids and materials. While the liter dominates everyday usage, the cubic decimeter is favored in technical contexts where a strong geometric interpretation is needed—for example, in tank sizing, volumetric flow calculations, or experiments involving water displacement.
